Fjorm the wall

This team clears the map fairly easely. Note that the healer must have Physic+ to work efficently. For the rest they all have their base sets. Just start the battle by going into the green manakete's range on the right with Fjorm and watch the whole enemy force going wasted against Fjorm. Fjorm must have Distant Def 3 SS (i have her +1 merged neutral IV S summoner supported too but i think any Fjorm can do it as long as they use their base setup). Only BK will be the other one that's gonna do something as he'll tank the green mage while almost killing it leaving the kill to Fjorm
