Thank you. This has been shaping up nicely. While Affliction looks cleaner and plays more elegantly, I am inclined to go Weaken because of its granularity. It's play by post anyway, so I'm not shying away from bookkeeping.
The fluff is a hearty roar. I am aware that they could partially or totally deafen themselves. Maybe that's a bad idea?
Speaking of bad ideas, how about linking duplicate powers but one hits Will, the other Fort? Been done before? Boring?
