Okay just to clarify, ONLY the ice ones are weak to a specific spell it does not do any mega damage on the desert or the jungle, only the ice ones. Bring some sort of healing familiar and anti-poisons are a must. Watch out for the dig attack it can hit twice on some rare cases (trust me I know I died)..... Also a EE or SGS will also help. Truly these guys are so weak a whip and a defender rips the apart. Hope that helps.
