Borderlands 4 Weekly Update Notes - May 14, 2026

Grenade builds just got a lot more interesting. This week's Borderlands 4 update is headlined by a wave of Grenade Ordnance buffs, with several weapons seeing damage jumps that should push them from situational picks into viable options.

The standout is the Jakobs Spinning Blade, which landed a +200% damage increase. Gearbox's own dev note acknowledges the skill ceiling involved in catching the knife after a hit, so the reward for pulling it off needed to match the effort. The Ripper Grenade Buoy also jumped by +150%, with the devs admitting its activation range wasn't working as intended in actual combat. On top of that, the Destructo Disco's Groove ability damage doubled, and the Daedalus Buzz Axe climbed by +50%. If you've been sleeping on grenade-focused builds, this is a reasonable moment to revisit them.

The update also introduces Borderlands 4's first-ever Quadruple Threat for Big Encore Bosses, framed as a birthday celebration for Robby, the designer behind the Weekly Big Encore setup. A developer birthday doubling as a community event is a nice touch. Restart your game to make sure the update applies correctly and avoid matchmaking issues. Everything in the update is listed below.
