I have no problem whatsoever with Cha 21. Go for it!
Isn't ray of enfeeblement 1st level in 3e?
How about shapechange for its 9th level spell, horrid wilting for its other 8th level spell, insanity, contagion, and extract water elemental (from Spell Compendium)?
We don't really use anything from Spell Compendium, but GrayLinnorm's other suggestions sound good. That is: shapechange, horrid wilting, insanity, & contagion.
Ray of enfeeblement still hasn't made it all the way to 1st level.![]()
Good point on those.
How about wail of the banshee? There's something appealing about a blob of slime mold suddenly screeching like crazy.
I like your suggestions for 6th and 7th level. That leaves us one more for each of those two levels. How about freezing sphere, as we don't use that often? Perhaps finger of death at 7th level?
I must have miscounted there somehow. Or read the numbers as those remaining.
I think I like polymorph best of your 4th level suggestions, but that duplicates the 8th level selection a bit. Wall of Ice might work at 4th level instead. I actually don't like illusions (hallucinatory terrain, for ex) as much for this, because they sort of imply some kind of mind in the victim, but I guess a glamer works on animals, so it's ok if you want to keep it.
