omg it piss me off! I CAN'T WIN WITHOUT POTIONS! I am disappointing me.
I did the hunt last night. The battlefield was smaller than I was anticipating, and those creatures take up a fair amount of room. Freeze (+2 Royal Weapons + Hypno Crown) put a dent in the Malboros and outright killed their spawn. After switching back to my strength gear, I kept warping around to try to get behind the Malboros and pick them off. Then it was back to the magic setup, another Freeze, and only the Malbodooms were left. A couple of link strikes later, the Armiger finished them off (and the Armiger Chain never gets old). I think I used 3 elixirs - two for Prompto and one for Ignis. Piercer and Regroup helped out, while Tempest (with Break Damage Limit, no less) was much less effective than I thought. (And obviously, 4 Ribbons were, uh, mildly useful).
