My first build. It excels both in pvp and pve but in terms of skills its up to you . You just gotta understand how the Iaito and Black Knight GreatSword moves , the stun locking and the angles and stuff and ur good to go. Added Pyromancy to aid you in desperate situation but more for PVE and you will have like 1 or 2 slots i think but just stick with great combustion or the black flame combustion so that you can minus stamina off ur opponents easier which gives u an opening to strike em
