Ifrit-egi should change to Debuffer, no point for Summoner to have 2 DPS because Garuda will be always most powerful pet Summoner can have (unless Leviathan in future patch prove more useful than Garuda)

Make it able to cast debuffs reduced target P.def and M.def OR P.atk and M.atk in cost of itself low and slow atk so its something usefulness on hard content like Coils of Bahamut

BTW, for Leviathan-egi in future (after Level cap raised and expansion)

I have idea how its work (my guess 100%), Leviathan based on Water element, Its probably something like + max Hp + max Mp and def up stuffs
