Vex' Incarnate Bleed build specializes in Kinetic Bleed damage, using Jakobs Weapons to trigger the effect.
This Build features Lifesteal and Damage buffs alongside the Bloodletter Bleed Skill, allowing you to deal high amounts of damage against end-game bosses, setting it as currently one of the most overpowered builds available.
Lifesteal Incarnate Bleed Vex Build

This build relies heavily on Dead Ringer, and your minions' damage. With heavy investment in The Fourth Seal, this build specializes in dealing massive single target damage, designed to burst down bosses, regardless of weakness.
For Weapons, we highly recommend having Incendiary, Shock, and Corrosive at least for your guns, to specifically target the different weaknesses of enemies. We also recommend having at least 1 Jakobs Weapon, which you should equip and use to proc your lifesteal, when backed into a corner.

This build centers on the Phase Phamiliar action skill, along with passives that boost survivability and damage. Equip SMGs with Vex to focuse on fast-paced close-range combat, and take advantage of Tediore weapons and accessories for their powerful grenade reloads.
Vex has three distinct skill trees, which allow her to play as a summoner or as an offensive caster. With the right skill investments, Vex has one of the highest DPS available in the game currently, either with Elemental Status, or with her own Bleed.
With Vex' build flexibility, head to the comments and let us know which Vex build you are using for your current playthroughs!
