Dark Mania

As an action, you speak beguiling words at a creature, forcing it to make an Intelligence saving throw. Succeeding the saving throw causes nothing to happen. Failing the saving throw twists the reality of the creature, warping it`s perception and feelings. The afflicted creature has their Passive Perception reduced by -5, their AC score reduced by 2, their sight is reduced to 30 feet and it takes additional damage equal to the caster`s casting ability modifier when the creature suffers damage.
