Infection is a seraph pistol in Sir Hammerlock's Big Game Hunt manufactured by Maliwan. It can be obtained as a rare drop from Voracidous the Invincible, Dexiduous the Invincible or Omnd-Omnd-Ohk in Ultimate Vault Hunter mode, or from the Seraph Vendor in Hunter's Grotto.

Special Weapon Effects

Itchy. Tasty. – Always corrosive, extremely high elemental effect damage & chance but extremely low projectile damage. Projectiles travel in a slight arc at a low velocity and explode after traveling a certain distance.

Usage & Description

What the Infection lacks in raw power, it makes up for in damage over time. The Infection has the highest elemental damage-per-second in the game and is extremely effective against armored enemies. It is also impossible to use at long range as the rounds detonate after a set distance. Against non-armored targets, it can still stack a high amount of DoT, although it will be resisted and is ineffective against enemies that can't be corroded.


  • The Infection deals an additional 80% splash damage that is boosted by grenade damage bonuses.
  • A Siren with 5 points invested in Flicker and a class mod that boosts Flicker by 5 points (namely the Legendary Siren class mod), it is possible to have a 100% chance of inflicting corrosive damage over time with the Infection.
    • Alternatively, a Witch class mod paired with either an Elemental or Bone of the Ancients relic can also achieve a 100% damage-over-time chance with this weapon. This may be easier to acquire, though it lacks the other benefits of a Legendary Siren class mod.
