So in a sea faring campaign I will soon be taking place in I was wanting to use this weapon. I was going to flavor it as swinging an anchor around.
Any ideas on how to use it in a build.
Most reach builds that emphasise enemies drawing attacks of opportunity from you are what you're looking for here. (Well, that, and the juicy sound of an anchor smashing into an enemy.) Also don't forget that AoOs are even more important to you here--as they're at +2 to your attack while normal mundane combat is -2. I don't know if Power Attack would be a good idea on this sort of thing given that.
