The first two new tiles are curses: Doomed and Stand up. If a player is cursed with Doomed, they cannot escape from the temple until lifting the curse. If a player is cursed with Stand up, they must remain standing until lifting the curse.

The third new tile is a treasure: Counterspell. Counterspell can be used to discard one curse card.
