Well, did my final try on the golden wolves and managed to destroy it even if i messed up.

Deployed Echidna, 3 mages and Solano and they killed the first gold wolves before the other two even reached Bernice. I messed up and forgot to use Karma on the first wolf but since she managed so well i used Karma on one of the two last wolves instead :P

Some serious firepower when you have 4 "mages" and a summoner.
