Not better than sever artery on a regular hit and gives bonus if target is KD'd . I was thinking about removing an ench if target foe is hexed but maybe that would be too over for pvp.
most people only bring sever to trigger gash. if you could go straight to gash like you could dismember, i highly doubt a lot sword wars would bother with sever anymore.
Lacerating Chop. If target foe is knocked down, you strike for +10...20 Damage and that foe suffers from Deep Wound for 5...20 seconds. This attack cannot be blocked.
