I think we can cut out the energy immunities, but leave him immune to disintegration.

Immunities: Ythog-Nthlei is immune to polymorphing, petrification,  or any other attack that alters his form. Any shape-altering powers he might have work normally on himself. He is immune to  mind-affecting effects (charms, compulsions, phantasms, patterns, and  morale effects). His Beyond Nature and Beyond Time and Space abilities means Ythog-Nthlei cannot be affected by effects that imprison or  banish him. Such effects include 
banishment, 
binding, 
dimensional  anchor, 
dismissal, 
imprisonment, 
repulsion, 
soul bind, 
temporal stasis, 
 trap the soul, and turning and rebuking. 
Ythog-Nthlei is not subject to energy drain, ability drain, or ability  damage, disease and poison, stunning, paralysis, and death  effects. Ythog-Nthlei  is also immune to damage from disintegration.
