Gazal Machete/Djinn Build
This build focused entirely on Gazal Machete/Djinn synergy. Each kill increase damage of Fatal Attraction, meanwhile Djinn will give you Corrosive damage buff. This way there are four different status effects, so Condition Overload gives you 320% damage buff (almost twice more than Primed Pressure Point). Carnis Mandible buffs Slash damage so it have biggest value overall and also increase Status Chance. Using lvl 1 Vicious Frost and Virulent Scourge instead of Carnis Mandible isn't an option because it will make Slash and Viral have same value.

Mods:

Condition Overload - Main damage buff

Vicious Frost/Virulent Scourge - Viral damage buff

Berserker Fury - Attack Speed increase

Primed Smite Grineer - 1.55x damage buff, could be also swapped for Primed Smite Infested too.

Primed Reach - range buff, especially important due to stances circular attacks

Molten Impact - Fire damage buff

Carnis Mandible - Slash damage buff and Status Chance buff. Set bonus rarely used (if used at all). This mod is better choice than Jagged Edge or Buff Kill due to its Status Change increase.
