Unless I'm losing my mind, I thought the FAQ listed Frost Axe and Frost Blade with separate profiles. Since the Axe of Morkai states that it can be used as a powerfist or FROST BLADE, my friends and I have been using it with the frost blade profile.Yeah, hopefully they'll fix Grimnar as well. The reason he had the stats for both axe and PF was so he could strike at his base initiative if he needed to, or use the fist against beasties if the situation calls for it.
Then the broke him. It is a ridiculous situation that two of the greatest characters in the game such as Dante and Grimnar strike after hormogaunts.
