When I use my sword, I only use the charge attack. I love my ascended calibur because of it's 360 degree hit and it's knock back. I'm looking for another sword though with a great charge attack. Something that knocks enemies back and doesn't just hit the locked-on enemy. For example, forward striking weapons only are not for me.
The Troika series has amazing knockback on charge, a chance to stun upon impact, and has surprising range capable of striking multiple enemies. Unfortunately the general area of effect is forward.
