Well finishing the game as level 42 mage was already quite challenging. It just feels sooooo good to hack and slash through those Verdistis sewers like a hot knife goes through butter. Or to cut through a pesky group of assasins with the easy you would cut the grass in your garden.
To be honnest, I just tested the frost weapon and it is indeed quite handy but with my trusted claymore I get the same result in half the time so for the moment I just keep the frost-weapon for unforeseen heavy resistance (Muriel for example).
