Best Kill Skills in Borderlands 4
Grave Fiends is the strongest all-around, since stacking raw damage boosts both gun builds and minion builds. Grave Quickening is crucial for skill-heavy builds because it constantly refills your Action Skill uptime.
Sanguine Fiends adds needed sustain in mob-heavy areas, but shines most when paired with other healing passives. Blight Attunement is one of the more unique skills, spawning extra minions that deal damage over time and refresh on more kills, which makes it powerful for corrosive-focused builds.
Blood Sacrifice deserves special mention since it lets you activate Kill Skills without landing the final blow yourself. This creates synergy in builds where minions die often but cycle back quickly.
Final Blurb
Kill Skills in Borderlands 4 turn momentum into raw power. By chaining kills and keeping pressure on enemies, you can stack up damage, cooldowns, and survivability to ridiculous levels. Vex benefits the most, with multiple stacking Kill Skills and unique triggers that make her minions part of the cycle. Mastering these passives is key to farming, bossing, and surviving high-difficulty content.
