I don't understand how the (4) Wizard bonus is supposed to work. It says "If you trigger the unique non-Wizard race/class skill during the combat round, unlock all of its layers".
I once saw somebody who had apparently done it with Mechs. I tried this too with 3x mech but it didn't work (not with win or lose). Also didn't work with the 3x goblins.
How to use the (4)-wizards correctly?
