Legendary weapons belong to orange tier list in Borderlands 4. These legendary weapons have a unique advantage for the player because of its gimmicks, unique traits and overpowered mechanics. Like a shotgun shoots rockets instead of pellets or a grenade that homes endlessly on target like Chaumurky Legendary Grenade.

How To Unlock Chaumurky Legendary Grenade In Borderlands 4

These legendary weapons in Borderlands 4 does not have an exact location, you can only guess according to the probability of dropping in certain area or as a loot drop after a boss fight. I was able to get this as loot drop from two locations as a loot drop after Boss Fight. It’s just that the chance of getting Chaumurky Legendary Grenade in those two locations is maximum.

Location #1 (Pitted Stain)

In Fadefields, go to The Pitted Stain where you will fight the Foundry Freaks. If you have already fought them you can spawn them again by using Moxi’s Big Encore.

Go to Moxi’s Big Encore by spending 3000 cash to re-spawn the Boss on Ripper Drill Site.

Pitted Stain location

The Foundry Freaks are three bosses, Frank the Furnace, Hank the Welder, and Sal the Engineer each boss has its own strong and weak points that you need to counter.

Frank the Furnace:

His attacks are fire based and throwing flames, creating lava zones on the floor. To counter him stay mobile and try long rang attacks on him. Don’t try to fight him up front and close.

Hank the Welder

More like his name throwing flame projectors and creating area of residual heats. Use some abilities like cryo to decrease the heating effect and keep yourself mobile. Flanking is a good counter for him.

Sal the Engineer

Supporting his name his attacks are gadget based most likely turrets and bots. Best way to counter her that don’t dive her time to build any defenses and focus on the shields, bots or any devices that she deploys.

A quick tip is that the level of these bosses is high if you try to beat them under leveled you will not be able to defeat them and that is frustrating.

Location # 2 (Saw’s Clench)

The second location where the chance of getting Chaumurky Legendary Grenade is higher is at Saw’s Clench. Go to Moxi’s Big Encore and spend some cash to re-spawn the Boss at the drill site.

Saw’s Clench in borderlands 4

Defeat the trio of Baby Grunt, Gruntabulous Vork, and Lil’ Grunt and respawn them until you get Chaumurky legendary Grenade as loot drop.
