Orobas et le Joyau prismatique

L'Ancien Orobas de l'acte 2 a ~8% de chances de proposer le Joyau prismatique — 33% de chances qu'il entre dans le pool, puis 1 chance sur 4 d'être choisi.

When visiting the Ancient Orobas in Act 2, there's a 33% chance the Prismatic Gem is added to Orobas's first relic pool (alongside Electric Shrymp, Glass Eye, and Sand Castle). If it doesn't appear, Sea Glass (from another character's pool) takes its slot instead. Since one relic is randomly picked from the pool of 4, the actual chance of being offered Prismatic Gem is ~8.3% (33% × 25%). This relic makes card rewards include cards from ALL character pools. Orobas also offers starter relic upgrades: Burning Blood becomes Black Blood, Ring of the Snake becomes Ring of the Drake, and so on.
