Vex Infinite Damage Build
Vex infinite damage build Borderlands 4: stacks Phase Leech, status DoTs, and Skull Orchid / Directive 0 to keep damage windows rolling without dropping clone uptime.
Playstyle
Keep Dead Ringer marks refreshed, rotate elemental DoTs so Phase Leech never idles, and only swap guns between clone casts. The goal is continuous damage ticks rather than single burst magazines.
Skill path
- Phase Leech first - ammo and health on status kill
- Incarnate DoT amp and elemental chance nodes
- Spectre clone duration, then Dead Ringer refresh
- Ignore pure burst nodes that break the DoT loop
Recommended weapons
Gear
- Class mod with status chance and clone duration
- Shield with elemental resist (fight lasts longer)
- Repkit that refunds action skill cooldown on kill
- Ordnance with corrosive or radiation DoT
Alternatives
- Hot Slugger swap if Skull Orchid rolls are dry
- Standard Best Vex Build for shorter boss phases
- Kaidos Fang for vault guardian crit pockets
Farm notes
Skull Orchid farms from Dominion chest loops; Directive 0 rotates through Order bunker guaranteed legendaries. Practice the DoT rotation on Bio-Bulkhead before Timekeeper.
