On p. 136 of the Monsters Manual, Evil Eye is an Action that applies damage (or half on a failed Charisma save). The next entry in Actions is the Curse of the Evil Eye, which says:
With a stare, the fomorian uses Evil Eye, but on a failed save, the creature is also cursed with magical deformities. While deformed, the creature has its speed halved and has disadvantage on ability checks, saving throws, and attacks based on Strength or Dexterity.
Does the Curse of the Evil Eye apply when the Evil Eye saving throw is failed, or does it require a seperate Action to apply?
