Borderlands 4 boasts numerous powerful Legendary Assault Rifles, yet the Wombo Combo distinguishes itself by hurling elemental explosives along with its ballistic barrage. Identifying its source proves straightforward compared to other high-tier gear. Below are the details.
Locating the Wombo Combo Legendary Assault Rifle in Borderlands 4

The Rippa Roadbirds’ trio battle at Saw’s Clench Ripper Drill Site may yield the Wombo Combo upon defeating any member.

Accessing the combat zone involves traveling to northern Carcadia Burn within Kairos’ western sector. Fast return becomes viable after unlocking Judgement’s Lapse Order Silo, enabling swift revisits via this landmark.

Three adversaries comprise this mechanical trio:
- Baby Grunt – Cryo-based defenses
- Gruntabulous Vork – Pyro shielding
- Lil’ Grunt – Electric protection
Eliminating any Roadbird member provides potential access to the rifle. Combat complexity arises from aerial bombardment patterns and swarming minor enemies during engagements.
Optimized character builds simplify shield penetration, though bomb clusters frequently trigger revival sequences. Repeated engagements follow a tedious reset process involving environmental navigation.

Efficient pathing entails ascending debris mounds and pipe networks adjacent to the combat area, reducing reset duration despite inherent frustrations. Multiple encounters typically yield valuable upgrades alongside level progression benefits.
Alternative acquisition exists through Maurice’s Black Market vendor rotations. Given the game’s extensive arsenal, weekly inventory checks may provide unexpected opportunities to secure this weapon.
