What to know

  • Ohm I Got is a Legendary SMG made by Maliwan, with the unique passive of consuming your Energy Shield instead of ammo to increase damage.
  • First required is progressing the main story to the mission Another Day, Another Universe.
  • Location: “Elpis Orbital Shatterfield” in the Carcadia Burn region. The boss “Moon-Maddened Callis” (sometimes “Second Ripper Queen” / “Ripper Queen” depending on source) is the key drop enemy.
  • You can farm the boss via the Encore Machine after first defeating them in the story, to keep trying until Ohm I Got drops.

Borderlands 4 has introduced a variety of epic loot, but one fan-favorite and fun-to-use weapon is Ohm I Got. This legendary submachine gun stands out due to its unique energy transfer ability, which drains your energy shield to boost its damage output, making it a powerful option for players who manage their shields well. Its design and firing sound are a direct homage to Ghostbusters' Proton Packs, adding to its appeal from a pop-culture standpoint.

Where to find and unlock the Ohm I Got weapon

Step 1: Progress through the main story to “Another Day, Another Universe”

The story mission Another Day, Another Universe is a checkpoint. Completing or reaching this mission unlocks the area where the boss is located.

Step 2: Travel to Elpis Orbital Shatterfield in Carcadia Burn

This is the specific region where Moon-Maddened Callis (or “Second Ripper Queen”) fights are held.

Step 3: Defeat the boss once in the story

You’ll face Moon-Maddened Callis during the mission. Defeat them to gain story progression and to unlock the ability to farm them.

Step 4: Use the Encore Machine to rerun the boss fight

Once the boss is defeated, you can use the Encore Machine or similar replay/farm mechanic to face them repeatedly until Ohm I Got drops.

What makes Ohm I Got special

This SMG shines particularly in its energy mechanics. When the player’s Energy Shield is active, the Ohm I Got consumes the shield’s energy instead of ammo, boosting the weapon's damage by 50%. Importantly, this damage boost doesn’t drain Overshields, and with the right shield mods that replenish or grant Overshields on damage, players can effectively achieve infinite ammo, making it powerful for sustained combat.

The weapon deals ongoing shock damage which is especially effective against shields, making it both fun and efficient in combat scenarios where enemies have significant shield protection.

Tips for increasing drop odds and optimizing farming

Tip Details
Level-match or be slightly overleveled Make sure your character is at an appropriate level for Carcadia Burn, so damage is sufficient.
Farm during or after major updates / patches Sometimes loot drop rates or boss rewards may be tweaked.
Improve your shield / energy-shield build Since Ohm I Got uses your Energy Shield instead of ammo, having a strong shield helps both your offense (damage bonus) and survivability.
Be patient — drop is RNG Even with farm methods, legendary drops can take many runs. Use speed-run strategies or multi-loadout approaches to reduce downtime.

Building your loadout around Ohm I Got

Obtaining Ohm I Got can become a rewarding long-term goal for players who enjoy combining shield management with high DPS output. Pairing it with shield mods that provide energy regeneration or Overshield will enhance its unique ability, turning it into a nearly infinite ammo powerhouse that can dominate shielded enemies. This makes it an exciting addition to any build focused on energy shield synergy and fast-paced combat in Borderlands 4.
