Waterfall is legendary grenade ordnance in Borderlands 4 manufactured by Vladof. It is obtained randomly from any suitable loot source, but has an increased chance to drop from Bio-Bulkhead located in Synthetic Nave - Dissected Plateau, in The Fadefields on Kairos.

Special Weapon Effects

I'm only going to ask this once. Who. Is. JASON?!

• Waterfall – Causes additional explosions when damaging targets.

Trivia

• The weapon's name and flavor text reference "Jason Waterfalls," a running joke in the Borderlands games about a common mishearing of the line "don't go chasin' waterfalls" in the 1994 song "Waterfalls" by the hip-hop group TLC.
