(Mods still WIP)
Haven't done much testing, but trying to narrow down best melees for [Kullervo].
Community says [Reaper Prime] because it has slash procs, but most melees have the same slash on heavy, and Two handed nikanas have slash and a lift on heavy, and i think they're the only one with the lift.
Among the TH Nikanas, its sort of hard to tell the best out of [Azothane], [Tatsu Prime], or [Tenet Livia], as they all have their own benefits. Azo has higher range but lower base damage but high crit, [Tatsu] has innate rad and status chance, and this has the elemental thing and a balance of crit and status. In classic min max fashion, I chose big number in modded dps.
Further, theres a list somewhere of heavy attack damage multipliiers, which changes depending on weapon type and sometimes others, so i may look into if any are high enough to swap to a different melee type. Theres also other factors I could look at; I read somewhere that [Keratinos] might also be good for inflicting mass slash procs, but i believe anyone you hit would get one no matter what, and optimally you'd have a chain that just kills everyone anyway.
I tried a lot of decent melee's for unmodded advance damage, and [Tenet Livia] performed better than most of them, though some, like [Edun], did significantly more damage, but without that slash proc, and not enough to compare to the total damage including the proc.
If a spreadsheet i found can be trusted, all of the following types have slash procs on heavy:
Claws
Dagger
Dual Daggers
Machete
Nikana
Rapier
Scythe
Tonfa
Two-handed Nikana
Warfan
Whip
I do need to test further if its worth using blood rush and/or [Sacrificial Steel], [Killing Blow], or possibly [Focus Radon]. [Berserker Fury] seems optimal, as getting the first kill is easy enough, but it could be sacked for something else and run no attack speed. Riven would be nice but I'm not including one, i [Hate] smite mods, but could be decent, and melee damage and crit chance are so over saturated that [Sacrificial Pressure] or [Primed Pressure Point] are both not worth it. Update to come.
