Build Overview

Updated for Level 70 & DLC2


Infinite Critical Hits. Critical Funding paired with Nuclear Winter and Group Study is what provides this. Building into Critical Damage is key in this build. Nuclear Winter also gives Bonus Cryo and Radiation Damage depending on if you're inside or outside of the Flux Generator. Any ways to increase this damage also helps out here, same with increases to Fire Rate. Triggering or Re-Triggering your action skills gives you multiple bonuses from Group Study, and our Zero-Point skills further build into that.

Strengths And Weaknesses

  • Mobbing is cake
  • Bossing is a breeze
  • Overshield adds to survivability
  • Flexible gear

Firmware is simple, 3 Deadeye for Critical Hit Damage Bonuses, and 2 High Caliber for Projectile Speed & Gun Damage. Skillcraft is also a viable option, but it only applies to your Bonus Elemental Damage from Nuclear Winter.

Specialization

Specialization 2Fragmentation Payload
Specialization 3Riddle You This
Specialization 4One Shot, One Kill

Riddle You This further increases Gun Damage, likewise with One Shot, One Kill. For the NEW Raid Boss, Subjugator and Thol, swap out The Best Defense for Now With Caffeine for uptime if needed between phases.

Gameplay

Super simple gameplay loop, pop your Action Skill, shoot enemies, and Re-Trigger your Action Skill as much as possible, to provide plenty of bonuses across the board to you through Group Study, Parallel Circuit and Bright Future. Once your Action Skill runs out, continue shooting to get your Action Skill back fast through Confirmative Reality. If using Trooper, toss some Ordnance in while shooting to add to the damage.
