Organian Undead Mob and Necromancy

Skeletal beasts can be: *animated (once killed obviously) *cursed *slept (? Their legs buckle slightly, but I never actually got one asleep) Skeletal beasts cannot be: poisoned weakened slept *disruption-ized**vampiric touched *=This seems buggy ** Vampiric touch doesn't work, which seems right, but it gives no echo. Basically, most of the spells give a message about the beast being undead, but disruption doesn't work. And even though they're undead, their bodies can be animated. Maybe they're supposed to be sort of half-undead in this way, but it seems sort of odd, especially that vampiric touch gives no echo, though it does use mana. Obviously this is all area explore stuff.
