If you are truly worried, make a weak party with whoever you want but it must have Mog
Give Mog a spear, the Paladin Shield and the snow scarf...
Give him his charm until you run into a dragon, then switch to the Dragon Horn+Boots
If your Mog is even a decent lvl, he can solo every Dragon alone this way, for all physical attacks do 1 and he absorbs/blocks every spell except flare
