When this spell is cast upon a construct, it takes on more of the qualities of a living creature. The construct gains the full benefit of spells from the healing subschool. In addition, the construct becomes subject to critical hits, sneak attacks, nonlethal damage, stunning, ability damage, ability drain, death effects, and necromancy effects. Further, an ironborn affected by this spell loses its racial fortification against critical hits and sneak attacks (including any improvements to that fortification).
The spell counters and dispels lesser construct essence and construct essence. If this spell is cast on a creature under the effect of lesser construct essence, the latter spell is automatically ended. if this spell is cast on a creature under the effect of construct essence, both spells are dispelled and have no effect. It has no effect if cast on a creature under the effect of greater construct essence.
