Krieg the Psycho offers one of Borderlands 2’s most distinctive and challenging playstyles. While his high-risk, high-reward mechanics excel in standard combat, raid bosses present unique obstacles that require specialized approaches. These endgame encounters demand thoughtful build optimization, gear selection, and tactical execution to overcome their massive health pools and devastating attacks. Let’s explore how to transform Krieg from a chaotic berserker into a methodical raid boss destroyer.
Krieg’s core advantages
Before diving into specific strategies, it’s essential to recognize Krieg’s inherent strengths against raid bosses:
- Sustained damage output – Properly built, Krieg can maintain consistent damage even during extended fights, mainly through DoT (Damage over Time) effects and his Release the Beast transformation.
- Health recovery options – Several skills provide robust healing mechanisms, especially valuable during prolonged encounters where attrition becomes a factor.
- Second wind potential – Krieg’s explosive damage capabilities make securing Second Winds more reliable than many other Vault Hunters.
- Damage reduction – Several skills reduce damage significantly, helping mitigate the attacks typical of raid bosses.
Hellborn – Fire-focused approach
The Hellborn tree offers exceptional sustainability against most raid bosses through its combination of elemental effects and health regeneration:
Key skills
- Elemental Empathy (constant health recovery while burning)
- Numbed Nerves (damage reduction while on fire)
- Fire Fiend (increased fire rate and damage while burning)
- Flame Flare (extended burn duration)
Equipment focus
- Flame of the Firehawk shield (creates nova explosions while depleted)
- Moxxi weapons (particularly the Grog Nozzle or Rubi for health leech)
- High burn chance/damage weapons like Hellfire or Good Touch
- Legendary Torch class mod (boosts fire rate and elemental effect chance)
Tactical approach – Intentionally set yourself on fire to activate Hellborn skills, then leverage the damage boost and sustain to maintain constant pressure. The Flame of the Firehawk shield becomes exceptionally powerful as you rarely allow your shield to recharge, creating a continuous nova effect.
This build excels against Pyro Pete, Hyperius, and Master Gee but struggles against fire-immune bosses like Voracidous.
Mania – Bloodlust berserker
For raid bosses vulnerable to melee damage, the Mania tree offers extraordinary burst damage potential:
Key skills
- Release the Beast (transform at 33% health for massive damage and damage reduction)
- Silence the Voices (huge melee damage boost with self-damage risk)
- Salt the Wound (increased shotgun and melee damage after taking damage)
- Feed the Meat (health and shield bonuses)
Equipment focus
- Rough Rider shield (always counts as depleted, activating many skills)
- Sheriff’s Badge relic (pistol damage and fire rate boost)
- Rapier (200% melee damage bonus)
- Face-puncher shotgun (converts melee damage to shotgun damage)
- Sickle class mod (boosts melee damage)
Tactical approach – Use Release the Beast for its 100% health restoration, damage reduction, and timing transformations to maximize uptime. Position yourself carefully against bosses with critical hit spots to land Buzz Axe strikes on weak points.
This approach works well against Terramorphous and certain Invincible bosses with accessible critical hit locations.
Bloodlust – Explosive specialist
For raid bosses that resist close-quarters combat, the Bloodlust tree offers ranged effectiveness:
Key skills
- Bloodbath (grenades and explosives generate more explosives)
- Blood Overdrive (kill skills boost gun damage and critical hit damage)
- Fuel the Blood (increased explosive damage after melee kills)
- Bloodsplosion (enemies explode on kill, chaining damage)
Equipment focus
- DPUH (Double Penetrating Unkempt Harold) for massive explosive damage
- Slagga or other reliable slag weapons
- Chain Lightning grenade (instant damage and easy application)
- Explosive Fastball grenade (enormous single-target damage)
- Legendary Reaper class mod (increases kill skill duration)
Tactical approach – Build Bloodlust stacks quickly with fast-firing weapons, then switch to high-damage explosives. For raid encounters with adds (additional enemies), use Bloodsplosion chains strategically, killing smaller enemies near the boss to trigger massive explosion chains.
This build performs exceptionally well against Ancient Dragons of Destruction and Dexiduous the Invincible.
