FL4K is “the Beastmaster” class in Borderlands 3. With these various skill trees, you can create some very powerful character builds for FL4K. FL4K has the ability to select 1 action skill and 1 pet. On top of each skill tree, you will find 1 of each and you can mix and match them up. You can equip 2 augments for your action skill. The Augments down each skill tree only work with the action skill from that specific skill tree. There are also augments that will replace your pet with a beefier version of that pet.
Skill Trees
- Stalker
- You’ll find plenty of ways to up your survivability in the Stalker skill tree; maybe you’ll opt to simply increase FL4K’s maximum health, or choose a passive skill that shares FL4K’s health regeneration with allies and doubles the bonus for their Pet. Staying healthy is a major part of maximizing your effectiveness with the Stalker skill tree, which includes such life-saving skills.
- Master
- The Master skill tree offers plenty of ways to increase your Pet’s damage output, like a passive skill that causes their first melee attack against an enemy to be an automatic critical hit. Beyond providing cover fire, FL4K can directly aid their Pet through skills.
- Hunter
- Critical hits are crucial to the Hunter skill tree, with plenty of passive skills that reward you for hitting your quarry’s weak points. You may get a chance to restore ammo to your magazine after a critical hit, or potentially reduce your Action Skill cooldown. Other options provide boosts to your Hunter Skills – a special type of skill found in all of FL4K’s skill trees.
- Trapper (DLC)
- The Trapper skill tree focuses on shields and survivability for both FL4K and their pet.
