The term “enemies” refers to Cultists, monsters, and the Elder One (once it’s summoned to the board). Any enemy that’s not a Cultist or the Elder One is a “monster”. Anything that refers to Cultists affects Cultists only. Anything that refers to monsters affects monsters only. Anything that refers to the Elder One affects the Elder One only.
Enemy cards show their health, the dice they use when attacking, and a special ability that may come into effect in different circumstances.
