Power: Sweltering Heat - While Cthugha stirs in its slumber, each investigator loses 1 Stamina for each movement point over 3 he spends each turn. Reading Tomes does not count towards this total. In addition, all Weather cards are ignored when drawn - a new card being drawn instead.
Attack: Roll a die. Each investigator must lose a total of that many Clue tokens, Stamina, and/or Sanity or be devoured. Any weapon used in an attack against Cthugha is discarded after the attack is made.

Cthugha first appears in The House on Curwen Street (1944), written by August Derleth.
