This guide will show you the locations of all arcanas in Castlevania: Belmont's Curse.
Arcanas are rewards for defeating bosses, and you'll use them as special abilities throughout the game. They're required for specific endings, to access specific areas, and for 100% completion of the game.
Paris Streets
Arcana #1: Cursed Flame
Story-related. This is your first arcana, and you already start the game with it.
Arcana #2: Holy Cross
Obtained after defeating The Fallen at the Gate to the Catacombs.
Arcana #3: Infernal Pyre
Obtained after defeating Joan in the Upper Tower.
Arcana #4: Chains of Justice
You can get this arcana in the Palace of Justice. To do so, you need at least half of all the Health / Mana upgrades. After that, talk to The Judge and it will start draining your health and mana. As a reward, you'll receive this arcana.
Holy Innocents' Cemetery
Arcana #5: Petrifying Gaze
Obtained after defeating Medusa in the Serpents' Lair.
Arcana #6: Mirror Walk
