Partially updated, returned to the game recently but still haven't looked into everything
This is the standard melee combo build for slash based weapons, as such it is applicable to almost any melee with the following...
Required Weapon Stats (These are rough approximations, if your weapon is very close it's probably fine)
- >=10% Crit Chance
- >=1.5x Multiplier
- >=10% Status Chance
- >=40% slash bias(or stance force procs a lot of slash)
This build is best used with a primer (a weapon to proc a lot of status effects (buffs condition overload), primarily viral which removes the need for it on the melee). Kuva nukor/Cedo are two notable primers.
Mod alternatives
- Primed Smite > Normal Smite
- Primed Fury > Quickening > Gladiator Vice > Fury
- Primed Reach > Spring-Loaded Blade > Normal Reach(or just swap in something else like gladiator might)
- Blood Rush/Weeping Wounds/Berserker/Condition Overload/Berserker(If you don't have any or all of these just get them)
-Other mods: Gladiator Vice
Notes
If you don't like the idea of faction mods cause you'd ideally swap them out for each faction, you can just keep it on grineer all the time and maybe swap for corrupted. Most Infested/Corpus are weak.
Normal Faction Dmg mod is a 1.69x multiplier to status damage. Primed Faction Dmg mod is a 2.4025x multiplier to status damage. (1+0.3)^2 and (1+0.55)^2 respectively since it applies twice to status effects.
If you have any questions regarding this build I encourage you to ask in the Warframe Community Discord(best place to learn how to mod and things about the game in general)
