How to get the Waterfall Legendary grenade in Borderlands 4?

To get your hands on a grenade, you’ll need to progress through the ‘One Fell Swoop’ main quest and reach the Order facility that is manufacturing Loctus. There, you’ll encounter the Bio-Bulkhead boss, who has a chance to drop the Waterfall grenade.

Unless you’re underpowered, the fight is pretty simple. However, you can’t simply nuke the boss in one hit due to multiple immunity phases. As you enter the area, the boss is immune to all damage, and the only way to remove it is by using Loctus canisters.

The arena has two dispensers that will provide a steady supply during the fight. Each time you deplete the boss’s armor, it will go immune, and you’ll need to throw the Loctus to remove the effect. Defeating the Bio-Bulkhead has a chance to drop Waterfall or other legendaries in its rotation pool.

The Waterfall Legendary grenade comes with a unique perk called ‘Waterfall’, which causes additional explosions when damaging a target. On hitting nothing in its AoE, the effect will not trigger, but when it deals damage to others, there will be a secondary explosion.

What the Ordnance doesn’t mention is that the secondary explosions can also trigger Waterfall. If you increase the blast radius big enough, it can chain between enemies. However, the interaction isn’t consistent and needs a bunch of enemies to trigger the explosion.
