Build Overview

Gun Gal Vex!

40s BLOOMREAPER KILL UVH6 TRUE MODE

This is a Vex gunslinger style build that has a flexible focus on bleed and general gunplay.

The build has very potent baseline damage for just about anything. It abdicates most kill skills in favor of stacking passive damage boost to hit big numbers without needing to play around Mortal Terror.

The main focus is on the shoot-reload loop of strong, bursty weapons, but all kinetic weaponry is valid here, from the slow and precise to the fast-firing, or any mix of the two.

A video guide is also available! For PC players: here's a decrypted save file.

Interested in a kill skill build? I recommend LDKSVB.

Strengths And Weaknesses

  • High damage
  • Decent weapon variety
  • Kinetic focus. Can use elemental weapons but ideally through quick swaps

Build Variants

Very specific setup. Not tailored to general play. It's specifically tweaked for UVH6 Bloomreaper platinums, even on True Mode, using specific gear.

It also makes platinums on lower difficulties/scaled UVH6 even easier.

If you want a setup that can do this but still play the game well using other things, check out Dronemancer Vex.

Weapons

Torgue AR/Potato Thrower IV with 'Airstrike'

  • For destroying crystals and orbs

Darkbeast with Jakobs (Ricochet Accessory) and, preferably, Daedalus Shotgun Mode

  • If you don't have the Torgue ARs or enough Splash Radius for the Airstrike on the orbs, the Darkbeast is a great fallback.

Linebacker is an excellent alternative for crystals and orbs.

Convergence with Jakobs (Ricochet Accessory) is also another great alternative for crystals.

Maliwan Shotgun with 'Beam Tossers', in fire element, for melting Bloomreaper itself once it's not immune.

Other options for damagin and finishing off Bloomreaper include the Jakobs Shotgun 'Spread Launcher' or Oscar Mike 'Space Laser'.

Supporting Gear

Order Repkit or Triple Bypass with Amp.

'Crit Knife' Jakobs Grenade.

Teen Witch or your best-rolled Psion.

Guardian Angel, Watts 4 Dinner or any other shield with 150% Amp.

Head Ringer Torgue Enhancement. Ideally with an additional splash radius boost, like Gun or Assault Rifle Splash Radius, so that you can hit the orbs with the Airstrike underbarrel.

  • Alternatively, swap one tier of High Caliber for one tier of Airstrike, in case you don't have enough radius boosts to use the 'Airstrike' Torgue AR underbarrel.

Gameplay

Tips

Remain mobile. Grapple. You can re-grapple to a previous grapple point without touching the ground as long as you grapple to another point first, then aim back at the previous.

Staying mobile and on the air is the easiest way to avoid getting pushed off and sniped by kreeps.

Use Incarnate a bit after you're done with crystals and orbs, unless you need it for more damage during that phase.

Weapons & Usage

Goes without saying: use repkit for Amp and Blood Shot before using any big burst of damage.

Use Torgue AR/Potato Thrower IV 'Airstrike' underbarrels for Crystal Phase. Once for crystals, once for orbs.

  • This requires Head Ringer Torgue Enhancement. With an additional splash radius boost on top of that, it can be enough to end the Orb phase with the Airstrikes too instead of having to use Darkbeast.
  • Alternatively, use Airstrike once on crystals then swap to a Darkbeast to finish off the orbs if you don't have enough radius boosts.
  • Another choice is Linebacker, which can be excellent for both crystals and orbs.

For the remaining phases:

Maliwan Shotgun 'Beam Tosser' underbarrel is excellent. Ideally fire through the boss so it hits as many times as possible then bounces back for more hits. Other options for damaging Bloomreaper include the Jakobs Shotgun 'Spread Launcher' or Oscar Mike 'Space Laser', alongside other potent underbarrels you may have.

For the final phase after immunity, Maliwan Shotgun 'Beam Tosser' is still great, but if you don't have another, the Jakobs Shotgun 'Spread Launcher' or Oscar Mike 'Space Laser' can usually finish the boss off.
