Combat Rewards

Pity counter (PotionRewardOdds.CurrentValue): Starts at 40%. After each combat the counter moves ±10% — down 10% if a potion drops, up 10% if not. There is no hard cap in the code (the underlying AbstractOdds.CurrentValue is an unclamped float). The constant targetOdds = 50% is a design target, not an enforced ceiling.

Elite bonus: The source constant eliteBonus = 25% is halved when applied to the roll: currentValue + eliteBonus * 0.5. So the effective Elite bonus is +12.5%, not +25%. That bonus is added to the drop threshold for one roll only — it is never written into the pity counter. The roll is a single check (rng < currentValue + bonus); if it passes you get the potion and pity moves −10%, exactly like any other drop, even when the potion only landed because of the bonus.

Bosses roll just like monsters. The reward switch in RewardsSet.GenerateRewardsFor calls the same RollForPotionAndAddTo path for Monster, Elite, and Boss. Bosses don't get the Elite bonus, so they roll against the bare pity counter, and the result moves the counter ±10% like any other combat.

What the Elite bonus actually does

The bonus shifts where the drop / no-drop line sits; it does not change which way pity moves. In every combat the rule is the same:

bonus is 12.5% for Elites and 0 for Monsters and Bosses. So a drop always lowers pity and a miss always raises it — there is no outcome where a drop leaves pity higher. The Elite's +12.5% only widens the drop side of the line: it makes a potion more likely, but a bonus-driven drop still spends the full −10% of pity, so an Elite borrows against your future drop chance rather than handing out a truly free potion.
