My personal [Sobek] build I use with [Saryn]. fitted to deal as much damage so toxic lash initial hit and the following damage over time it does.

Two toxin mods and another from riven to boost the damage of toxic lash.

Primed Chilling Grasp and other elemental mods boost the base damage of Sobek so toxic lash deals more damage on initial hit and therefore bigger DOT.

[Shotgun Barrage] to improve our burst damage if need to hit tougher targets like acolytes.

RIVEN can be replaced with Primed insert anti faction here mod. This again boost our toxic lash damage.

ROAR on Saryn to boost all damage even more.

The following set up above double and triple dips our damage causing Sobek with Acid Shells to melt steelpath enemies with ease.

We do not use Primed Point Blank since we have primary merciless. they do stack but with diminishing returns so we better of with other mods.

Take it for a spin and have fun.
