Change Shape [>] (concentrate, polymorph, primal, transmutation) The shadow yai takes on the appearance of a shadow giant. This doesn't change its Speed or Strike attack and damage.

Shadow Touch A shadow yai's touch harms their target's spiritual essence in addition to its body. A creature hit by the shadow yai's fist Strike must attempt a DC 36 Will save. Critical Success The creature is unaffected.Success The creature takes 2d6 negative damage.Failure The creature becomes drained 1 and takes 3d6 negative damage. As long as the creature is drained as a result of this ability, it loses the ability to speak above a whisper. When the creature attempts to Cast a Spell with a verbal component, it must succeed at a flat check or the spell is disrupted. The DC of this flat check is equal to 5 plus the creature's drained value (for example, DC 7 if the creature is drained 2).Critical Failure As failure, but the creature becomes drained 2 and takes 6d6 negative damage.
