Raggis

Raggis is a large virmen found at the Ki-Han Brewery on the Wandering Isle. He's preventing the farmers from working on the brewery. Dai-Lo Recess Mallet can be found sitting on a barrel near him.

Strategy
Raggis can burrow underground and keep attacking. Ranged characters should have no issues with this mob, melee however should use caution and stay away from Raggis while he's burrowed. A couple of Dai-Lo Farmers will aid you should you get close to them as well.
