Council of Ghosts

An Act 2 event where three masked spirits offer their power for half your health.

Council of Ghosts is an event that only appears in Act 2 of Slay the Spire. Black smoke rises around the player and forms three masked shapes, who discuss the player as one of Neow's puppets and offer a share of their power. Accepting gives five Apparition cards (three on Ascension 15 and up) at the cost of half your maximum HP; refusing does nothing.
