Base Attack/Grapple:
/??? rather high
Attack: Unarmed Strike (as this is DnD based, like a monk presumably) not sure how DnD hit chances are calculated but shuld basicaly always hit, 2d20 blunt damage plus 3d20 electric.
Full Attack: most likely using matter manipulation to chese the enimys existance, if no accses to magic then a series of 2d6 mele blows as mentioned abowe, or use of weapon.
Space/Reach: variable depending on form/variable depending on form.
Special Attacks: Spell-like abilities, spells, mater/energy/magic/spacetime manipulation (Examples: create a gigajoule laser beam, create antimatter inside foe, greate graviy wave and somhow attack whit it)
Special Qualities: Change shape, low-light vision, immunity to electricity, loads of minor abilities for the god of magic to give, all the other stuff I've forgoten, and usualy huge amount of varus learned stuff Zyenild is suposed to spesify.
