I can't escape the mind of Pelagius, because I can't get complete the "Confidence" task. First I zap Anger with the Wabbajack twice to make him small, then he conjures his two pals (upon whom the Wabbajack has not effect), then I zap Confidence with the Wabbajack and he becomes big.

Then...Sheogorath is supposed to chime in and tell me job well done, right? Only he doesn't. The summons keep whaling on Confidence until he's small again, then they disappear. And the whole cycle starts again. Am I missing something, or am I bugged?

Zap confidence twice to make him big, zapping him once will only make him medium sized and the self doubts will beat him back down to small.

ya, when you zap confidence and he gets big the first time that's just 'medium', he can go up one more size. so, from small size there are 2 sizes up to finish it.

Ah, thanks, folks.
