Pro Tips for Maximum DPS

  • Mayhem 10/11 Strategy: Focus on elemental matching and critical hits due to massive enemy health scaling. Anointments are key.
  • Weapon Choice: High-damage, single-pellet weapons often outperform multi-pellet weapons at high Mayhem due to how damage is calculated.
  • Elemental Matching: Always match your element to enemy weaknesses for maximum effectiveness. Carrying multiple elements is essential.
  • Splash Damage: Area-of-effect (splash) damage is a separate multiplier and is extremely powerful on characters like Moze.
  • Action Skills: Many action skills scale better than weapons at high Mayhem levels. Don't neglect them!

Character-Specific Strategies

Amara (Siren): Her elemental and action skill damage bonuses scale excellently with Mayhem. Focus on elemental builds.

FL4K (Beastmaster): Critical hit bonuses from skills like Fade Away provide consistent high damage. Pet damage also scales with Mayhem levels.

Moze (Gunner): Splash damage bonuses and Iron Bear are incredibly strong. Focus on explosive weapons and bottomless magazine builds.

Zane (Operative): His kill skills and SNTNL drone provide excellent damage scaling. Stacking multiple action skills is powerful.
