Burrower

A powerful worm type creature with great Health, Strength and Armor. They can only be found in a unique story portal.

A giant sized, Max Level 5 Burrower will join with Qitou if you recruit her. You won't get much use out of Burrowers, much less the weak one that joins with Qitou, as you should already have end-game set-up and a full party by the time you reach the wasteland.
