Roil is a legendary submachine gun in Borderlands 4 manufactured by Ripper. It is only available as a reward from the Happy Mercenary Day Vault Card added to the game as part of Bounty Pack 1: How Rush Saved Mercenary Day.

Special Weapon Effects[]

Sleep down in the soil.

  • Hydropower – Overheating prevents firing. Switching modes reduces heat.
  • Always spawns with a COV-licensed magazine.

Notes[]

  • This weapon is sometimes listed online as "Aching Roil," but this is only guaranteed to be the name of the first instance of the item generated by the Mercenary Day Vault Card. It can also generate with other prefixes, as seen in the item card on this page.
