The Tarot holds 15 numbered Arcana cards, each tied to a character, and the maps mark 37 spots where you gain Arcana, spells and movement abilities or meet people. Most cards come from boss fights, while the Ferryman and Eleanor give you theirs. Each card grants a spell, a movement ability or both: The Shadow gives Soul Harvest and Double Jump, The Artist gives Masterpiece and Aerial Rush, and The Sage gives Mirror Walk.
Paris Streets and Notre-Dame hold 9 spots each, with 5 in the Clock Tower and 4 in the Main Hall. Along the way you meet Trevor, Eleanor and Sypha, and you also cross paths with the Succubus and the Ferryman.
