Vex Skill Tree Guide in Borderlands 4
There are three action skills available for Vex. These are:
- Phase Phamiliar
- Incarnate
- Dead Ringer
Below are further details on them.
Phase Phamiliar
The first Action Skill for Vex is Phase Phamiliar, where her Minion, Trouble, fights alongside her. One of its standout features is that if Trouble is defeated, it will automatically respawn after a short cooldown.
Additionally, you can press F to manually teleport Trouble to a target location, dealing area damage on arrival. After teleporting, Trouble transforms into a Badass, fully restoring its health and gaining increased damage for a short time. If Trouble is dead when you trigger Phase Phamiliar, it will be revived immediately.
- Trouble Respawn Cooldown: 20 seconds
- Trouble Damage: 18
- Trouble Respawn Damage: 82
- Cooldown: 45 seconds
- Duration: 20 seconds

Incarnate
During the Incarnate skill, Vex unleashes a Phase Explosion to damage nearby enemies and completely restore her health. During its active stages, she gains bonus movement speed and can also use a secondary attack called Eldritch Blast.
To do so, you need to press L1 to fire the move from her offhand, dealing damage to nearby enemies. Additionally, dealing Gun damage during this time reduces Eldrich Blast’s cooldown. You can also press and hold F to manually cancel the skill early, which partially reduces the cooldown.
- Phase Explosion Damage: 151
- Eldrich Blast Damage: 100
- Eldrich Blast Cooldown Reduction: 2.5%
- Movement Speed: +25%
- Cooldown: 55 Seconds
- Duration: 25 Seconds
Dead Ringer
Vex can summon a Phase Clone minion by choosing between two types: Specter or Reaper. These Clones gradually lose health over time, and their damage type matches Vex’s current elemental attunement when spawned. You need to press M1 to summon a Reaper, which taunts nearby enemies and deals melee damage. Also, press M2 to summon a Specter, which uses gun attacks from a fixed position but cannot move.
- Reaper Damage: 29
- Specter Damage: 8 per shot
- Health loss per second: 5%
- Health loss increases per second: +4%
- Cooldown: 35 seconds
