To much work....do you have the mascot dressphere?Equipe two of your characters with it and give them each a speed bracer and whatever raises their HP the most in your inventory.Then do the catnip/gunner thing (make sure your gunners health is low at the start of the battle) then move your X-potions to the top of the inventory list and when the Paragon or trema attacks (even if it doesn't do that much damage) have one of your characters use an X-potion unless it's your gunner thats been attacked.Just use a phonix down on her.
