If you're new to Slay the Spire 2, the game can feel overwhelming fast. Between deckbuilding, relics, map choices, and brutal bosses, it's easy to lose run after run.
In this guide, I'll walk you through the core strategies every new player should know so you can start winning runs much faster.
Whether you're coming from Slay the Spire or jumping in for the first time, these tips will help you climb the Spire.
First, it's important to understand what kind of game Slay the Spire is.
Slay the Spire is a roguelike deckbuilding game at its core. That means every run through the Spire is completely different, and your progress resets when the run ends.
When you start a run, you begin with a basic deck of cards and very few resources. As you climb the Spire, you'll fight enemies, collect relics, and add new cards to your deck. These choices shape how your deck evolves during that run.
But the key idea of a roguelike is that failure is part of the experience.
If your character dies, the run ends and you start over from the beginning. You don't keep the deck you built, the relics you found, or the upgrades you earned. Instead, the next run begins fresh with a new map layout, different card rewards, and new opportunities.
Because of this, success in Slay the Spire isn't about grinding levels or unlocking stronger stats like other roguelikes. Instead, the real progression comes from learning the game's systems and making better decisions over time.
Each run teaches you things like:
Over time, you start recognizing patterns, synergies, and strategies that help you climb higher.
So the goal isn't to build the perfect deck every run. The goal is to build the best deck you can with the choices you're given.
That's what makes roguelikes like Slay the Spire so engaging: every run is a new puzzle to solve.
At the start of a run in Slay the Spire, you'll choose a character to climb the Spire with. Each character has their own starting deck, relic, and unique set of cards. These differences shape how each character plays and what strategies they tend to favor.
While every character can defeat the Spire, they each approach combat in slightly different ways. Understanding these differences can help you decide which character fits your playstyle best.
While each character in Slay the Spire 2 plays differently, the core skills of deckbuilding, planning your route, and adapting to relics apply to every run. Experimenting with each character is one of the best ways to learn the game's systems and discover new strategies.
Over time, you will discover which of the characters you like playing the most. But to start out, just experiment and try them all out.
The map in Slay the Spire represents your path as you climb the Spire. Instead of moving freely between rooms, you travel along branching paths of connected nodes, choosing your route from the bottom of the map to the boss at the top.
Each node on the map represents a different type of encounter or event, and the path you choose can greatly affect how strong your deck becomes during the run.
Regular enemy fights are the most common nodes on the map. Winning these fights usually rewards you with gold, a card reward, and sometimes a potion. These fights are one of the main ways you build and improve your deck throughout the run.
Elite enemies are much stronger than normal enemies, but they offer much better rewards. Defeating an elite always gives you a relic, which is a powerful passive bonus that lasts for the entire run.
Because relics are so impactful, fighting elites is one of the best ways to grow stronger — but they also carry significant risk if your deck isn't ready.
Campfires give you an opportunity to either rest to recover health or upgrade a card in your deck. Upgrading cards can make them significantly stronger, so campfires are often an important part of preparing for tougher fights ahead.
Shops allow you to spend gold on cards, relics, potions, and card removals. Removing weak starting cards can make your deck more consistent, and shops are often a good place to find powerful relics that can shape your strategy.
Event nodes contain random encounters that usually present you with choices rather than combat. These might give you relics, gold, cards, or other benefits — sometimes at a cost.
Events add variety to each run and can occasionally provide powerful advantages.
At the top of every act is a boss fight. Bosses are much tougher than regular enemies and usually require a well-built deck to defeat. Beating a boss rewards you with a boss relic, which is often one of the most powerful upgrades you can get during a run.
One of the most important skills in Slay the Spire is planning your route through the map.
Before you start climbing, you should take a moment to look at the entire map and think about questions like:
Choosing the right path can mean the difference between a strong deck that defeats the boss or a run that ends early.
Before starting your path on each act, scroll through the map and plan out a route that allows you to receive the most rewards for as little cost as possible. Plan around Campfires before each difficult fight, and shops to help you remove and add cards or relics to your arsenal.
Deckbuilding is the core of Slay the Spire. Every time you win a fight, you'll usually be offered a choice between several cards to add to your deck. Over the course of a run, these decisions shape how your deck functions and determine whether you'll be strong enough to defeat the bosses ahead.
One of the most important things for new players to understand is that you don't have to take a card every time you're offered one. In fact, skipping cards is often the best choice.
A larger deck means it becomes harder to draw the cards you actually need. Because of this, strong decks in Slay the Spire are usually focused and consistent, rather than filled with lots of random cards.
When you're deciding whether to take a card, try asking yourself a simple question:
Does this card solve a problem my deck currently has?
For example, early in a run your deck might struggle with dealing enough damage to enemies quickly. In that case, adding a strong attack card could make fights much easier. Later in the run, you might instead need more defense or a way to scale your power during longer fights.
In general, most successful decks balance three important elements:
Damage — You need reliable ways to defeat enemies before they overwhelm you.
Defense — Blocking damage keeps you alive long enough to reach stronger parts of your deck.
Scaling — Some fights, especially bosses, last long enough that you need ways to grow stronger over time.
Another common mistake new players make is trying to build around too many different mechanics at once. While experimenting can be fun, decks are usually stronger when they focus on a small number of synergies that work well together.
Finally, remember that your deck doesn't have to be perfect right away. Deckbuilding in Slay the Spire is about gradually improving your deck as the run progresses, adapting to the cards, relics, and opportunities the game offers.
The goal isn't to build the perfect deck from the start — it's to build the best deck you can with the choices you're given.
One of the most important skills in Slay the Spire is learning when not to take a card.
After most fights you'll be offered three cards, but adding a card isn't always beneficial. Every card you add increases the size of your deck, which makes it harder to draw the cards that are most important to your strategy.
Because of this, strong players skip card rewards much more often than new players expect.
A good rule of thumb is:
Only take a card if it clearly improves your deck.
For example, if your deck already has enough damage and the offered cards don't improve your defense or scaling, skipping may be the best option. Keeping your deck focused and consistent often leads to much stronger runs.
There isn't a single perfect deck size, but most successful decks tend to stay relatively small and efficient.
Smaller decks allow you to:
Many strong decks end up somewhere around 20–30 cards, though this can vary depending on relics, card draw, and strategy.
If your deck grows too large, it becomes harder to find the cards you need at the right time. This is why card removal at shops can be extremely valuable, especially for removing weak starting cards like basic Strikes or Defends.
Whenever you're deciding whether to add a card to your deck, it can help to ask yourself three simple questions.
If your deck struggles with damage, defense, or scaling, a card that fills that gap may be very valuable.
Some cards become much stronger when combined with certain relics or other cards. If the card supports your existing strategy, it's often a good addition.
Sometimes the best choice is simply to keep your deck the same. If a card doesn't significantly improve your deck, skipping can keep your deck more consistent.
Relics are one of the most important sources of power in Slay the Spire. Unlike cards, relics provide permanent passive effects that last for the entire run. These bonuses can range from small quality-of-life improvements to effects that completely change how your deck functions.
Because relics are always active and don't need to be drawn or played, they provide consistent value in every fight. Over the course of a run, the relics you collect can dramatically increase your strength and open up new strategies.
Relics can be obtained in several ways throughout the game. Defeating elite enemies always rewards a relic, making elite fights one of the most valuable opportunities to grow stronger. You can also find relics in shops, certain events, treasure rooms, and after defeating bosses.
Some relics provide simple bonuses, such as giving you extra gold or improving your starting hand. Others can have much larger effects, such as granting additional energy each turn or triggering powerful effects when certain conditions are met.
Because relics can influence how your deck performs, it's often a good idea to adapt your strategy around the relics you find. For example, if you obtain a relic that rewards playing many cards each turn, you might prioritize cards that generate energy or draw additional cards. If you find a relic that improves defensive play, you may want to build a deck that can stall longer fights.
This is one of the reasons elite fights are so important. While they are more dangerous than normal enemies, the relics they provide can dramatically increase your chances of winning the run.
Over time, you'll start to recognize how powerful certain relics can be and how they interact with different decks. Learning how to take advantage of relics—and when it's worth taking risks to obtain them—is a key part of mastering Slay the Spire.
While many relics provide simple bonuses, some relics are powerful enough to shape your entire strategy for the rest of the run. When you find one of these relics, it's often a good idea to start making deckbuilding decisions that take advantage of its effect.
Instead of forcing a specific deck idea from the beginning, strong players often adapt their deck based on the relics they discover. A relic might encourage you to play more cards each turn, focus on defense, or build around certain types of attacks.
When a relic significantly changes how combat works, try to think about how you can lean into that strength when choosing new cards, relics, and upgrades.
Here are a few examples that show how relics can influence your deckbuilding decisions.
Kunai gives you [[power:Dexterity]] after playing three attacks in a single turn. This encourages building a deck that can play multiple attack cards quickly, allowing you to stack Dexterity and gain stronger block every turn.
If you find Kunai early in a run, you might prioritize:
These help you trigger the relic's effect consistently.
Dead Branch adds a random card to your hand whenever a card is exhausted. This relic can create huge value in decks that already [[keyword:Exhaust]] cards frequently.
If you obtain Dead Branch, cards that exhaust themselves or other cards suddenly become much stronger. Decks that focus on exhausting cards can generate a constant stream of new resources during combat.
Ice Cream allows you to keep unused energy between turns. Normally, unused energy disappears at the end of the turn, but this relic allows you to store it for later.
This opens the door for strategies where you save energy during quiet turns and then unleash many powerful cards in a single explosive turn.
Runic Pyramid prevents your hand from being discarded at the end of your turn. This allows you to hold onto key cards until the perfect moment to play them.
Because of this, decks with Runic Pyramid often focus on:
One of the most important skills in Slay the Spire is learning to adapt your deck based on the relics you find. Sometimes the relics you obtain will naturally push your deck toward a certain playstyle.
Instead of trying to force a specific build every run, pay attention to the tools the game gives you. When a powerful relic appears, adjusting your strategy around it can turn an average deck into a run-winning one.
Over time, you'll begin to recognize which relics can completely change how your deck works—and how to take full advantage of them.
Campfires are one of the most valuable nodes you'll encounter while climbing the Spire. Unlike enemy fights or events, campfires give you a chance to improve your deck without risking damage.
When you reach a campfire, you're usually given two main choices: rest to recover health or upgrade a card in your deck. Both options can be extremely powerful, and choosing the right one at the right time can make a huge difference in the success of your run.
Resting restores a portion of your missing health. This can be crucial if your health is low and you're approaching a difficult fight, such as an elite enemy or the act boss.
Sometimes the safest choice is simply to heal and make sure you survive the next encounter. Even a strong deck can lose a run if you enter an important fight with too little health.
Because of this, campfires often serve as a way to recover from difficult fights and prepare for the challenges ahead.
Upgrading cards is often the more powerful long-term option. Many cards become significantly stronger when upgraded, gaining benefits such as:
Upgraded cards can dramatically increase your deck's effectiveness, and multiple upgrades over the course of a run can make a noticeable difference in difficult fights.
For this reason, experienced players often try to upgrade cards whenever it's safe to do so.
The real challenge of campfires is deciding when to heal and when to upgrade.
If your health is high and your deck needs improvement, upgrading is usually the better choice. However, if you're approaching a dangerous fight and your health is low, resting may be the safer option.
This decision often depends on what's coming next on the map. Before choosing, it's a good idea to look ahead and consider questions like:
Planning around campfires and using them wisely is a key part of climbing the Spire successfully.
Over the course of a run, campfires provide some of the most reliable ways to strengthen your deck. A well-timed upgrade can make your best cards even stronger, while a well-timed rest can keep a run alive when things get dangerous.
Learning when to prioritize upgrades and when to focus on survival is an important skill for new players, and mastering campfire decisions will greatly improve your chances of reaching the top of the Spire.
When visiting a campfire, upgrading a card can make a big difference in how strong your deck becomes. However, not all upgrades are equally valuable. Choosing the right card to upgrade can significantly improve your chances of surviving tougher fights.
A good way to approach upgrades is to focus on cards that give the biggest immediate impact.
Cards that you use in nearly every fight are usually great upgrade targets. Since these cards are played frequently, improving them will benefit you in almost every combat.
For example, upgrading a reliable attack or defensive card that you play regularly can add consistent value throughout the run.
Some cards become dramatically stronger when upgraded. These upgrades might reduce the card's energy cost, greatly increase its damage or block, or add an additional effect.
Upgrades that reduce energy cost are especially powerful because they allow you to play more cards in a single turn. Being able to play an extra card each turn can quickly swing fights in your favor.
If your deck relies on certain cards to start its strategy—such as cards that generate [[power:Strength]], apply powers, or create other long-term advantages—upgrading those cards can make your deck much more reliable.
These upgrades help your deck reach its stronger turns faster.
At the beginning of a run, you'll mostly have basic [[Strike]] and [[Defend]] cards. You will also start with 1-2 Common cards exclusive to your character. If you are in a pinch, upgrading these can still offer a lot of value if you have no other good options.
However, as your deck improves, you'll usually want to prioritize upgrading stronger cards instead of your basic starters.
The best upgrade choice can change depending on the cards and relics you've collected. Sometimes the best upgrade is a powerful attack, while other times it might be a defensive card or an important power.
As a general rule, try to upgrade cards that:
Over time, you'll start recognizing which upgrades provide the biggest improvements to your deck.
Simple rule for new players:
If an upgrade reduces a card's energy cost or significantly increases its effect, it's often one of the best upgrades you can choose.
Potions are single-use items that can provide powerful effects during combat. While they may seem like small bonuses at first, potions can often be the difference between winning and losing a difficult fight.
You can obtain potions in several ways throughout a run, including enemy fights, events, and shops. Your character can only carry a limited number of potions at a time, so deciding when to use them is an important part of the game.
One of the most common mistakes new players make is saving potions for too long. Because potions are limited, it can be tempting to hold onto them for a "perfect" moment. However, many runs are lost simply because players never use the resources they have.
Potions are meant to be used to solve problems in difficult fights. If using a potion prevents a large amount of damage or helps you defeat a dangerous enemy, it's usually worth it.
For example, a potion that helps you defeat an enemy faster may save you far more health than if you had tried to save it for later.
While potions can be useful in almost any fight, they tend to be most impactful in certain situations.
Elite fights are one of the best times to use potions. Elites are much stronger than normal enemies, and using a potion can make these fights significantly safer.
Boss fights are another important moment. Since bosses are often the toughest encounters in each act, using your potions can help your deck overcome their unique challenges.
Potions can also be valuable during dangerous hallway fights, especially if your health is already low.
Instead of thinking of potions as rare items to save forever, it helps to think of them as extra tools for solving combat situations.
Sometimes a potion will provide additional damage to finish an enemy. Other times it might give you extra block, card draw, or another temporary advantage.
Using these tools at the right moment can help stabilize a difficult run and allow you to continue climbing the Spire.
Since your potion slots are limited, it's also important to use potions so you don't miss opportunities to pick up better ones later. If your potion slots are full, you won't be able to take new potions that drop from fights.
Using a potion before a difficult encounter can both improve your chances in that fight and free up space for future rewards.
If using a potion will:
then it's usually the right time to use it.
Learning to use potions effectively is a small habit that can greatly improve your success in Slay the Spire.
At the end of every act in Slay the Spire, you'll face a boss. Boss fights are much tougher than normal enemies and often require your deck to handle longer, more demanding battles. Because of this, it's important to prepare for the boss while progressing through the act.
Boss fights are designed to test whether your deck is balanced and capable of handling sustained combat. While regular enemies might be defeated quickly, bosses usually require you to survive several turns while continuing to build your strength.
One of the most important things bosses test is scaling—your ability to become stronger as the fight continues.
If your deck only deals small, consistent damage each turn without improving over time, boss fights can become very difficult. Many bosses have large health pools or mechanics that make longer fights inevitable.
To handle these fights, your deck should ideally include cards that:
Scaling allows your deck to keep up with the increasing pressure that bosses apply.
Your health going into the boss fight can be just as important as the strength of your deck. Try to avoid taking unnecessary damage in the fights leading up to the boss so you enter the battle with as much health as possible.
Campfires right before the boss can also play a key role. If your health is low, resting may give you the survivability you need to finish the act. If your health is comfortable, upgrading an important card could give your deck the extra power it needs.
Potions can be extremely valuable during boss fights. Since bosses are the most difficult encounter in each act, having a potion available can give you a critical advantage.
For example, potions that provide extra damage, block, or card draw can help stabilize the fight during difficult turns.
If possible, try to enter the boss fight with at least one useful potion available.
Preparation for the boss begins long before the fight itself. As you progress through the act, think about whether your deck will be able to handle a longer fight.
When choosing cards or upgrades, consider questions like:
If your deck is missing one of these elements, it may be worth prioritizing cards that fill that gap before reaching the boss.
Boss fights are meant to test the overall strength of your deck. By building a balanced deck, managing your health carefully, and saving helpful resources like potions, you can greatly increase your chances of defeating them.
Learning how to prepare for bosses is an important step toward consistently climbing higher in the Spire.
Slay the Spire can be challenging when you first start playing, and many early losses come from a few common habits that new players develop. Understanding these mistakes can help you improve much faster and make better decisions during your runs.
One of the most common mistakes new players make is adding a card to their deck after every fight. While it might seem like having more cards would make your deck stronger, the opposite is often true.
Large decks make it harder to draw the cards you actually need during combat. Strong decks are usually focused and consistent, containing cards that work well together rather than a large collection of unrelated effects.
If a card doesn't clearly improve your deck, it's often better to skip the reward and keep your deck streamlined.
Elite enemies are stronger than normal fights, so it's natural for new players to avoid them. However, elites provide one of the most valuable rewards in the game: relics.
Relics provide permanent bonuses that can dramatically improve your deck's strength. Because of this, fighting a few elites during each act is often necessary to keep your deck powerful enough for later challenges.
While elites can be dangerous, learning when your deck is strong enough to take them on is an important skill.
Another common mistake is holding onto potions and waiting for the "perfect" moment to use them.
Potions are meant to help you survive difficult fights. If using a potion prevents a large amount of damage or helps you defeat a dangerous enemy, it's usually worth using right away.
A potion that saves your health now can often make the rest of the run much easier.
Healing at campfires can feel like the safest option, especially when your health is low. However, upgrading cards is often more powerful in the long run.
Upgraded cards improve your deck's performance in every fight, making future battles easier and reducing the amount of damage you take overall.
While resting is sometimes necessary, upgrading whenever it's safe to do so can significantly strengthen your deck.
Some new players focus only on damage cards and neglect defense, while others build too much defense and struggle to defeat enemies quickly.
Strong decks usually contain a balance of three key elements:
Keeping this balance in mind while building your deck can help you handle a wide variety of encounters.
Another mistake beginners make is choosing map paths without looking ahead. Planning your route through the act can help you prepare for difficult fights and take advantage of valuable opportunities.
Looking at the map before you begin climbing can help you:
Careful pathing can often make a run much safer.
Every loss in Slay the Spire is an opportunity to learn. As you gain experience, you'll start recognizing stronger card combinations, better relic synergies, and smarter paths through the map.
Over time, these lessons add up and make each new run more successful than the last.
Climbing the Spire isn't about winning every run—it's about improving your decisions and adapting to the challenges each run presents.
One of the most important skills in Slay the Spire isn't memorizing specific card combinations or strategies—it's learning how to evaluate decisions during a run.
Every run presents a different set of cards, relics, events, and enemies. Because of this, strong players focus less on forcing a specific deck and more on adapting to the options they're given.
When making decisions throughout a run, it helps to think about what your deck currently needs.
At different points in a run, your deck may struggle with different problems. Early on, you might lack enough damage to defeat enemies quickly. Later in the run, your deck might need more defense or ways to scale during longer fights.
When choosing cards, relics, or upgrades, try to ask yourself:
What problem does my deck currently have?
If your deck struggles to block damage, defensive cards may be valuable. If fights are taking too long, adding stronger attacks might be the better option.
Thinking about what your deck needs right now can help guide many of your decisions.
Another helpful mindset is focusing on the next major challenge ahead of you rather than worrying about the entire run.
For example, you might ask yourself questions like:
By preparing for the next obstacle on the map, you can make decisions that keep your run moving forward.
Many runs develop naturally based on the relics and cards you obtain. Instead of trying to force a specific build, it's often better to lean into the strengths your run gives you.
If you obtain relics that reward playing many cards, you might prioritize card draw and low-cost cards. If your relics support defensive play, you might build a deck that can survive longer fights.
Learning to adapt your strategy around what you find is a key part of mastering the game.
Throughout a run, you'll constantly make decisions about cards, upgrades, relics, potions, and map routes. Each of these choices may seem small on its own, but together they shape how strong your deck becomes.
Strong players develop the habit of thinking carefully about each decision and how it will affect their deck moving forward.
If there's one guiding idea to keep in mind while climbing the Spire, it's this:
Build the best deck you can with the choices you're given.
You won't always get perfect card rewards or ideal relics, but by adapting your decisions and focusing on your deck's needs, you can turn many runs into successful climbs.
With practice, this way of thinking becomes second nature—and each run becomes another opportunity to improve and climb higher.
Climbing the Spire for the first time can feel overwhelming. With so many cards, relics, enemies, and decisions to consider, it's normal for early runs to end in defeat. But that's part of what makes the experience so rewarding.
Success in Slay the Spire isn't about memorizing one perfect strategy or building the same deck every run. Instead, it's about learning how the game's systems work together and adapting to the options you're given.
As you continue playing, you'll start to recognize stronger card combinations, understand which relics can shape your strategy, and learn how to plan your route through each act more effectively.
Every run—win or lose—teaches you something new about how the game works.
If there's one thing to remember while climbing the Spire, it's this:
Build the best deck you can with the choices you're given.
With practice, smarter decision-making, and a little bit of experimentation, you'll find yourself climbing higher and higher with each run.
Good luck, and enjoy the climb.
