This is the snow monster correct??.....In your party you want Sarah, Random, Cocka (if levels are high enough), and Wendala! With Random Metallist Curse, attack up, and wail away! Sarah use pitiute calling if levels are high enough! That should be the best party line up! The walkthrough goes into the battle strategies more in depth so you can always check out the walk through and see what strategies and levels are needed to concur this beast!

side note: Cocka is used to help kill the Millipuves that appear towards the end of the battle!
