Ohm I Got is a Shock Maliwan legendary SMG associated with Moon-Maddened Callis at Elpis Orbital Shatterfield in Carcadia Burn. Game guides report that you reach the boss during the main story mission Another Day, Another Universe; after the story fight, use the Encore Machine for repeat attempts. The weapon is a possible drop, not a guaranteed reward.

Where to find Ohm I Got

Moon-Maddened Callis is the reported source for Ohm I Got. The encounter is at Elpis Orbital Shatterfield in Carcadia Burn; Game8 identifies the area as Fallen Crown, Carcadia Burn. Guides vary between “Carcadia Burn” and “Carcadia Burns,” but they refer to the same boss location. Game8’s location guide and Nerdschalk’s guide list the drop.

How to unlock Moon-Maddened Callis

Secondary guides say to advance the campaign to Another Day, Another Universe. Mobalytics describes the story fight as the “Second Ripper Queen” encounter; this is a label for the encounter associated with Moon-Maddened Callis, not evidence of a separate drop boss. The specific mission prerequisite is guide-reported rather than confirmed by an official quest walkthrough in the sources available here. See Mobalytics and Nerdschalk.

How to farm it after the story fight

  1. Progress the main story until Another Day, Another Universe and defeat Moon-Maddened Callis in the Second Ripper Queen encounter.
  2. Return to the boss using the Encore Machine, as recommended by the guides, to create further chances for the weapon to drop.
  3. Check the drops after each fight. No reliable current drop percentage or guaranteed number of attempts is established, so expect the result to depend on chance.

What Ohm I Got does

Ohm I Got is listed as a Shock Maliwan SMG. A community-edited item reference describes its Energy Transfer effect as using active Energy Shield instead of ammunition to increase damage; check the weapon’s current in-game description for the precise behavior.

Gearbox’s January 29, 2026 patch notes state that Ohm I Got “will no longer consume Energy Shield when Overshield is active.” This is a dated mechanics change, not a guarantee that the behavior has remained unchanged in every later update: official Borderlands Support patch notes.

On April 30, 2026, Gearbox also reported restoring missing prefixes to Ohm I Got so players could identify its special parts more easily. That update concerns weapon prefixes; it does not establish a change to the boss location or drop odds: April 30 patch notes.

Is it a current weekly reward?

Gearbox listed Ohm I Got as the Legendary Gear Reward for The Council Divided Weekly Wildcard Mission on October 16, 2025. That dated notice is historical; weekly rewards rotate, so it does not show that Ohm I Got is the current reward. For a dependable targeted route, use the Moon-Maddened Callis encounter rather than assuming the old weekly reward is still active. Gearbox’s Borderlands 4 news.
