Slow (Su): Any creature drained of at least 1 point of Strength by A'azzatz must succeed on a DC 24 Fortitude save or be slowed (as the spell) for x minutes (or maybe until the Strength is restored?). The save DC is Constitution-based.
I'd say we could do that, if Str is restored before the minute is up. But I wouldn't want to make someone wait until they're back to full Str; that might take a while, and I don't think he's quite that tough.
