work in progress
tldr:

• build has 1.4 million peak slash as is, if replace vile for bane (when have external fire rate), can go up too 3.5 million per tick (slash assumes 4 instances (yellow crit), headshot, viral, and stacked merciless/galv aptitude)
• galv ap is bugged and gives multiplicative scaling instead of additive (link for more info) (massive dmg but need to shoot twice - overall worth)
• if have external fire rate use bane over vile
• can add forma for exilus mod (i like terminal velocity but vig. supplies is technically more dps)
• i made a slash calculator that u can copy and use https://docs.google.com/spreadsheets/d/12OeFBa-LNXPRk97FoRe-G2lq8n1pTnZAs45S_APy8h8/edit?usp=sharing

quik math 4 big slash: (bane for vile config)
800 × (1+3.6) × 1.55 = 5704 (base dmg for formula)
0.35 × 6417 (base dmg) × 1.55 (faction bonus) × 6.6 (crit multiplier) × 3.4 (galv ap bug - see below) = 69438.7848
69438.7848 × 4.25 (viral) × 3 (headshot) × 4 (# instances) = 3,541,378.0248 (slash tick dmg)

edit: when i get back from vacation, I will farm sp for 3.5mil bleed (its hard bc u need things to actually live a couple hits with fully stacked conditionals)
