Monster Trap is a unique E-tech grenade mod in Borderlands: The Pre-Sequel manufactured by Vladof. The Monster Trap is a mission weapon during Guardian Hunter and Sterwin Forever.

Special Weapon Effects

Captures weakened Eridians. Does not consume grenade ammunition and deals minimal damage.

Usage & Description

The Monster Trap is a mission item with an exclusive purpose of trapping Eridians. It has a homing delivery mechanism, and a 1 point damage effect that erases a weakened Eridian from existence, and replaces it with a loot mission item specific to those two missions. There is no ammunition cost to throw a Monster Trap, so despite their limited application, they can also be thrown with impunity.


  • This is the only Legitimately usable E-tech item in Borderlands: The Pre-Sequel, and the second E-Tech grenade mod in the entire series.
  • The Monster Trap is a reference to a Pokeball.
  • It is the only grenade mod that is provided as a mission item.
  • Monster Trap can scale to a level that is higher than the Vault Hunters (Not in UVHM), making it effectively unusable and thus the mission will be unable to progress.
  • It is one of the few items that possesses a white flavor text.
