Notes from author
you will have a balder side sword+15 (or 14) and a chaos zweihander in your inventory, as well as a hornet and DWGR for different situations, parry and quickly switch to zweihander and hornet ring and you are guaranteed to at least take out 75% of your enemies hp, if not outright kill them, BDS and DWGR if you need to be fast, change the black knight set for something else, i recomend dark mask+ black cleric robe+ black knight leggins+ gold hemmed black gloves, looks good and will give you at least some poise (20, i think) you can also switch to chaos zweihander as main weapon if you feel it will help you, and of course, you got various pyromancies for different jobs, chaos fireball and power withing are self explanatory, you can use black flame if you riposte or stunlock your opponent for a guaranted 500-1200 damage, and chaos storm for close spaces or ganks (50 poise helps a lot here)
this is one hell of a build.
