On paper the cra "buff" looks op, but I've played them on the beta and it's not as strong as you'd think. Both of the powers from the spells last only until the end of your turn, so you would need to spend 7 ap at least to get the effects, and even then it doesn't last for spells such as Poisoned Arrow, or Tyrannic Arrow. Plus there's the -100mp you would need to deal with xD
They did give a nerf to cha osas, Slimy Toad's attacks don't trigger if cast on an ally now which is a pretty big nerf if you've ever played them.
I do agree with Consolation though, that was a dumb change.
