Petition to Remove Pap's Despell

If u are melee class, you can stay on top platform to avoid dispels.
If u are range class, just stand far enough.

 

If you are fighting it as a bishop, assuming you are pinning it in the left corner: you can stand to the right of the second "pillar" and reach it with angel ray/whatever attack you have while being out of range of its dispel. have your summon out to help clear the little poof balls. To pin it, stand as far from it as possible and slowly inch toward it until you can knock it back, repeat until its pinned.
