105 Enc recasting single target mez, on partial resist

[flatlined785]

My 105 enc keeps recasting Bewilder, the single target mez. The toon casts it on an add, that's fine, but then the mob IS mez'd and the toon keeps recasting it over and over.

I think it might be that this spell has 2 effects, mez and blur. It might be the blur is getting resisted. There does seem to be a partial resist message.
