Build Overview

BUILD BREAKDOWN

This vex build leverages Vex's insane firerate and killskill skill prowess by creating clever synergies between all 3 of her skill trees and some fun synergistic combos between the weapons and the skill tree.

Incarnate provides us with the ability to never need to reload via the use of Witchy Trigger Finger, thus optimising her Vexcalation toolkit to shine with the terrifyingly fun and lethal Wombo ComboAR.

The strength in this build lies in the fact it can blow through all tiers of content, doesn't rely on knife crit tech and has absolutely ZERO BLEED. A really welcome and refreshing change of pace when playing Vex!

The backbone of this builds focuses on the synergy between Grave Power, Grave Assault, Grave Implements, Grave Quickening, Grave Sights, the plethora of firerate increase skills and the wide range of flat damage increases we can gain from leaning heavily into overshield tech unlocked by Teen Witch.

Landing critical hits with with Wombo Combo and Mortal Terror means we are often sitting at 4 - 6 killskill activations. This, compounded by the permanent 6 stacks of Witchy Trigger Finger is absolutely HUGE!

Use Incarnate whenever it is off cooldown and you are fighting spam down enemies using your phase explosion and Elditch Blast, weaving shots in between. This becomes incredible when Vibe Check is live as you can spam Elditch Blast indefinitely, keeping our weapons full and our purple action skill bar topped off thanks to Grave Sustenance.

Complex Root absolutely ROCKS large bosses. This is the way to boss!!!
