If I am not mistaken, you can only put area effect spells into a living spell.
You are. You can put Area
or Effect spells in there. (Enervation/Energy Drain works because it has an Effect: Ray.) Still rules out Drown, though (Target).
You could toss on Glitterdust, Stinking Cloud, and Wings of Flurry-- Will save or blind, Fort save or sickened, Reflex save or dazed. Web's another cheap fun one, if they don't have Freedom of Movement yet.
MDJ would be terrifying, if cruel.
