I never read much about Balthazar's Spirit being used in W/Mo. Seems to me that this SHOULD BE a great enchantment to use, especially for hammer warriors. Consider: Hammer skills need a lot of adrenaline, however, they are the slowest to attack. This means that adrenaline builds very slowly. Also, warriors have the lowest energy (not using gladiator armor) so BS can provide both much-needed adrenaline and energy.
But like many other skills in GW, does it actually do what it says and is it useful?
I haven't really messed around with BS. I'm going to try it tonight, I just thought I'd ask for opinions first.
