Best Specialization For Best Vex Build
Below are the best specializations to invest the points in for the best Vex bleed build in Borderlands 4.
| Specialization | Points | Perk |
|---|---|---|
| Brute | 20 | Riddle You This |
| Sharpshooter | 10 | In The Zone |
| Killer | 10+ | Contamination Compounding Afflictions |
Add 20 points at least in Brute for the gun damage, and to get Riddle You This to stack 505 extra gun damage. After that, add 10 points into Sharpshooter to unlock Killer and slot in the zone for the additional gun damage and crit damage. Then pump Killer as far as you can. Slot in Contamination to boost your status effect chance, making you bleed things. And Compounding Affliction for that extra damage when things have statuses on them.
Brute is the best specialization to invest in due to multiple reasons, but mainly the enhancement in gun damage. Boost your reload speed and accuracy by investing points in Sharpshooter. Only 10 points are enough to boost critical damage and gun damage in Sharpshooter. Boost the damage based on the elemental effect applied due to Compounding Afflictions in Killer.
Best Firmware For Vex Bleed Build

| Huge Caliber | 2 | Projectile Speed is increased by +25%. Gun Damage increased by +10% Bullets Pierce enemies |
Invest points in Deadeye to gain 25% crit damage, then every crit gives you 155 for five stacks. You get another massive crit damage buff, stacking with that knife. So, Deadeye level three is a must-have in my opinion. Allocate two points in High Caliber for the additional projectile speed and a 10% increase in gun damage. You can put in whatever you like for these two slots. Oscar Mike is also the best option to invest your points for additional reload speed by 10% and gun damage up to 20%.
