excellent.
i gave some thought to the Alternate Form power. let me know how this looks:
Alternate Form (Su): Amduscias can shift between his humanoid, unicorn, and wolf forms as a standard action. In humanoid form, he cannot use his bleeding wounds, constrict, improved grab, or rake abilities, but he can use his slams and bite attack and can use weapons.
In unicorn form, he cannot use his constrict, improved grab, or rake abilities or make slam, bite, or weapon attacks, but he can use his horn and hoof attacks and his speed is 60 feet (12 squares).
In wolf form he cannot use his bleeding wounds ability, make slam attacks or use weapons, but he can use his constrict, improved grab, and rake abilities, his speed is 50 feet (10 squares), and he gains low-light vision, scent, and a +4 racial bonus on Survival checks when tracking by scent.
(one question – should the alternate form attacks be listed on the main attack line, or under the Alternate Form description?)
Amduscias remains in one form until he chooses to assume a new one. A change in form cannot be dispelled, nor does Amduscias revert to any particular form when killed. A true seeing spell reveals all forms simultaneously.
examples from the MM:
Alternate Form: quasit, imp, dragon (bronze, gold, silver), eladrins, lycanthropes, phasm
Change Shape: aranea, hound archon, barghest, doppelganger, rakshasa, slaad (green, gray, death)
