Great guide, ive been testing nagi sins through sigma and to me its both incredibly tanky and got great damage. Broad is my favorite.

My approach for this build is more ways/broad oriented, as i do believe rainbow damage is the best. Ive tried backstab but its bit unreliable and ive noticed huge part of bonus damage is ever wasted. Ive never used hades gate since im both lazy and for tougher content ive not noticed any speed kill increase (im not interested in chaining cows)
My weapon choice was always zular, its kinda obvious to me. Ive crafted countless nagis and tbh even +skill proc dmg + lasterblade -broad cd just suck comparing to zul.
For Armor choice strong starter for me always was Yaerius set. It got everything broad way sin needs.
I d have two remarks to Your build advice's.
AR is MOST important thing and you cant have enough. Imho ignore def weapon is mandatory for broad but if you dont have it you should stuff AR everywhere (and lets be real adding ignore to zular is kinda ....).
From TTAD (ive not tried knights/albrecht build for that so dunno) to DOOM, CB etc ive tried to increase my build damage and noticeably only DS was worth it. If one can afford, throwing few auches/rogue gloves will boost the damage significantly.
Currently ive got my hands on decent roll of Black Ice, the way how things go its very good, ill post some more feedback after id reach tougher content than cows
