I have never seen a regular monster dispel, some bosses do. As mentioned forgot about the daamn sharks.
I can only think of pap and horntail off the top of my head... And as mage, you won't be the dispel target at horntail (unless your host is an idiot). I think pianus dispels too... Not entirely sure.
thanks for the replies all, just trying to see what I should be trying to avoid as a mage haha. and yes learnt that sharks can dispel while fighting cold sharks for Elquines T_T @jessyjinx may I ask what's this "dispel mule" you've mentioned?
