Dibs..... why the **** is every single one of your characters ****ing broken?
It's not broken, he's level thirteen and he can barely take down someone with 50ish hit points, and he could only do that if he sticks and moves. He needs his skirmish/sneak attack to do it if you give him the DR. The one that is broken is just about every single high level caster. But luckily they do have a few *****s in the old armor, first if they run out of spells, second in places where magic is useless, and if they are in melee.
