I really wanna just kill a daedric prince, or princes. It was so fun in the past... and I really want to kill Molag Bal and Boethia... Like... if they both were fighting against each other, and then you came and fought them somehow, that'd pretty awesome, at least to me it would be.
Dragons are great. Daedra are better.

Impossible.

You've never fought a daedric prince in their true forms. The exception was Jyggalag, but by that point you were Sheogorath.
