Living Maximized Disintegrate
Nothing... simply nothing... That is all that is left in the wake of this massive, undulating form of sickening green energy. It has literally left a uniform hole in side of the castle wall, the barn, the burial mound outside of town, and the side of the mountain it came from. Even the trail it leaves behind is a trough a foot deep. And the scary thing that occurs to you is if this thing can burrow right through anything, why hasn't it burrowed all the way through the ground.

Spell Effect (Su): Each time the Living Spell successfully strikes a target with its slam attack, that target is affected by Maximized Disintegrate at Caster Level: 17th (204 points of damage, Fortitude DC 22 for 30 points). If the target has spell resistance, the Living Spell's caster level check is made once per strike, either allowing all spells or no spells to apply to the target.
Engulf (Ex): As per monster rules, Reflex DC: 30. The saving throw DC is Strength-based.
Spell Engulf (Su): Creatures that successfully engulfed are subject to Maximized Disintegrate at Caster Level: 17th (204 points of damage, Fortitude DC 22 for 30 points) each round. If a target has spell resistance, the Living Spell's caster level check is made only once per round per target, either allowing all spells or no spells to apply as appropriate. As the engulfed creatures are considered pinned, this will appropriately alter their saving throws.

This is example of what happens when magic, specifically the Disintegrate spell with the Maximize Spell metamagic feat, becomes twisted and congealed into a Living Spell, via the Living Spell template. Like all oozes, Living Spells are mindless, reactionary and has the standard ooze traits.
