Unholy Pharlan (18 Sorc/22 Blackguard)

I've been wanting to make a Bane Knight for some time but it was giving me quite a few problems. I admit I aint the best builder out there by a long shot but I have always made my own builds. In fact I don't think I have ever looked at other builds on the forums until I decided to make a Bane Knight.

NE ways here is my attempt at what I think is a decent BK build.

Subrace: Pharlan

STR +4, WIS +4, CHA +4
