So Attack of Opportunity doesn’t seem to do anything to spellcasters?

Hmm well does a spell require a manipulate action? I don't know the types of actions that well yet. on the plus side interrupting the action as part of your reaction does seem kind of nice. It just depends on what counts as a manipulation action.

Actually, Mark explicitly answered this back in the fighter preview thread.

So, the blog might not have made it clear, but most spells require the kind of fine manipulation that triggers an AoO (somatic gestures, material components).
