Effect You afflict a creature you can see with a hex of impending doom. The hex lasts for 1 minute. As long as the creature is hexed, when you hit it with a round from the hex blaster, the creature must attempt a DC 28 Will save at the end of your turn; the creature attempts a single Will save regardless of the number of times you hit it.

Critical Success The creature is unaffected.

Success The creature is Frightened 1. It also takes 1d6 persistent mental damage.

Failure The creature is Frightened 2. It also takes 2d6 persistent mental damage.

Critical Failure The creature is frightened 2 and Slowed 1 for 1 minute. It also takes 4d6 persistent mental damage and is cursed with a hex of impending doom. If the target falls Unconscious from damage dealt by this Strike or the persistent mental damage, it remains unconscious for 1 day or until this curse is removed. After 1 day, if the creature is still unconscious, it must succeed at a DC 28 Fortitude save or die; this effect has the death and incapacitation traits.
