Maybe make it also do X (or some multiple thereof) damage per round to anything it grapples, and it's ok. I find myself wishing for some way to make it more "chaosy" though.
Well the dissolution is in additional to the normal constriction/tentacle damage, right?
Revising...
Dissolution (Ex): The touch of a nameless limbo thing can convert any sort of matter into the random stuff of Limbo. Any time the thing hits with a tentacle or grapples an opponent (regardless of whether the grapple succeeds) it does an additional X damage by partially disintegrating its target, halved with a successful DC Y Fortitude save. This special attack does full damage to objects and ignores hardness. If a dissolution touch kills a creature its body dissolves into chaos, the remains are not sufficient for a raise dead spell to bring back to life. A nameless limbo thing can suppress its dissolution power if it wishes to keep a creature or object intact.
