When this spell is cast upon a living construct, it takes on more of the qualities of a true construct. The living construct gains the moderate fortification armor special quality, negating critical hits and sneak attacks 75% of the time. As well, the living construct gains low-light vision and immunity to nonlethal damage and stunning.

This spell counters and dispels lesser humanoid essence. If this spell is cast on a creature under the effect of lesser humanoid essence, both spells are dispelled and have no effect. It has no effect if cast on a creature under the effect of humanoid essence or greater humanoid essence.
