The Prophetess is Medusa’s Arcana card in Castlevania: Belmont’s Curse. It gives Rose the Petrifying Gaze spell, and the same fight also hands over one of the keys to the Catacombs.
Quick answer: Defeat Medusa in her flooded arena beneath Holy Innocents’ Cemetery, entered through the Serpents’ Lair. Then hold E (R1 on PlayStation) until absorption finishes, about ten seconds.
Where to get The Prophetess
Medusa holds The Prophetess. Her door is in the Serpents’ Lair under Holy Innocents’ Cemetery, and her arena is a flooded hall where you fight her across walkways above the water.
The Ancient Sewers Mirror of Life is close to her door, so save there before you go in. The route to the door and the fight itself are covered in how to beat Medusa.

Seeing both cards means the absorption worked. The Prophetess is yours, and Petrifying Gaze is ready to use.
What Petrifying Gaze does
The spell card reads “Petrify enemies in front of Rose.” In practice, it turns enemies standing in front of her to stone.
If that sounds familiar, it should. Medusa uses the same kind of attack on Rose during the fight, firing a beam from her eyes. Absorbing the card puts that power on your side.
What else Medusa leaves behind
The fight also awards THE PROPHETESS’S KEY, a key item. Its description reads “One of three keys needed to open the sealed door to the Catacombs. Obtained by defeating Medusa.”

The key goes into the Gate to the Catacombs together with The Fallen’s Key and The Warrior’s Key. To place all of them, follow our guide on how to open the Gate to the Catacombs.
If this is your third key, Rose says: “Medusa was absorbed into the ‘Prophetess’ card, and now I have the last key to the door.”
- Defeating Medusa earns the achievement: “Snakes speared in the ruins” (Defeat the Prophetess).
- Objective: GET TO THE GATE OF THE CATACOMBS replaces your current goal after the fight.
