Use grabs to increase Melinoë's passive perks
Complete Arcana Card Guide for Hades 2! | Haelian
by Ari Notis and Ryan Gilliam
Arcana cards are a crucial component of Hades 2, which is fitting, since the game turns you into a literal witch.
Like Keepsakes (accessories), Arcana Cards give you passive benefits, based on how much you hold. Some cards increase your stats. Some are even more helpful, going so far as to revive you from death. Unlike Keepsakes, though, think of Arcana Cards more like a skill tree. As you unlock more cards, you get access to even better cards.
