Buoy - Changelog

Update: May. 14, 2026

  • Ripper Grenade Buoy has received a +150% Damage increase.
Dev Note: The activation range and proximity check has proven to not be as practical in combat as we were targeting.
As a result, we’ve added a dramatic increase to the damage to better fit players using it as a short-range burst of damage.

Base Game Items in Borderlands 4 are often obtainable from many sources, including those in DLCs. Here’s your quick start guide:

Farming Preparations

  1. Identify the Best Source: The Sources below are generally ranked from best to worst. Make sure to complete any required quests and be aware of Source Restrictions.
  2. Locate the Source: Make sure you have unlocked the Location.
  3. Equip Your Character: Equip your character to easily overcome enemies.
  4. Set Spawn Point: Locate the nearest Save Station to use as your spawn point.

Bonus Tips

  • Combine Runs: Get more loot per run by integrating nearby sources into your farming route.
  • Track Progress: Track your runs to more precisely predict drops and more clearly monitor progress. Additionally, time your runs to see how tweaks affect your farming efficiency.
  • Speed it up: Explore shortcuts and boost your movement speed to minimize travel time. Also, aim to shorten your time to kill with higher DPS or big damage bursts.
  • Realistic Expectations: Be patient and persistent when farming. Despite precise, verified drop rates, your actual runs might exceed or fall short of inferred expectations.
