Borderlands 3 Fl4k Skill Trees - Stalker, Hunter and Master Action Skills explained

Everything you need to know about Fl4k, the robot beast master, in Borderlands 3.

Fl4k is one of the new Vault Hunters for Borderlands 3. Like all Vault Hunters, they have three Skill Trees for you to experiment with - Stalker, Hunterand Master.

Fl4k is a wandering robot on a quest of self-discovery through the stars. While their robotic heart feels a connection to the animal kingdom, Fl4k find the social constructs of humans confusing.

As Fl4k's Beastmaster title suggests, they are accompanied by three loyal animal companions - a skag, spiderant and jabber.

How Fl4k's Action Skills work in Borderlands 3

Fl4k can have one Action Skill, such as Fade Away, equipped at all times.

As you spend Skill Points, you'll be able to unlock Action Skill Augments that will add extra features to your chosen Action Skill. Fl4k can have two Action Skill Augments equipped at one time.

Fl4k can also have one of their pets accompanying them at all times.

Your choice of pets are the Jabber Sidekick, Spiderant Centurion and Guard Skag.

Each skill tree will allow you to upgrade to two different versions of each pet, such as the Beefcake Jabber. Each new pet you unlock has a new ability, increased Movement Speed for example, that help you tackle the bandits of Pandora.

New versions of your chosen pet will replace the one you currently have equipped.

Stalker Skill Tree for Fl4k in Borderlands 3

The Stalker Skill Tree is focused on regenerating Fl4k's health and increasing their Movement Speed for when fights get tough. The Fade Away Action Skill allows you to take enemies by surprise, while also offering you a chance to heal.

There are also a number of abilities, such as Hidden Machine and Overclocked, that allow you to up the damage that Fl4k can inflict by either increasing their Weapon Damage or Fire Rate.

The pet for the Stalker Skill Tree is the Jabber. This feisty creature can be upgraded to hold a Shotgun and, later, an SMG, while also boosting Fl4k's Maximum Health.

The Jabber is a good combination of a support allie and an offensive one; providing fire power when needed, but also attacking as a healer when things get tough. The Lick the Wounds ability is very useful, because it offers the Jabber a chance to revive Fl4k during a Fight for Your Life.

Hunter Skill Tree for Fl4k in Borderlands 3

The Hunter Skill Tree is all about upping your Critical Hit Damage, so that you can take out enemies as killing as possible. Abilities like Head Count and Hunter's Eye provide you with boosts to both your Critical Hit Damage and other stats that focus on harming enemies.

Rakk Attack!, the Action Skill for the Hunter Skill Tree, allows you to surprise your enemies with a horde of bats. (If you've played a previously Borderlands game, you know how annoying these bats can be.) Not only can you give these bats the ability to deal Elemental Damage, but you can add to your Rakk collection with the Flock 'N Load ability.

The Spiderant Centurion is the pet of choice for this skill tree. Like the Jabber, it partly acts like a healer - allowing Fl4k to constantly regenerate health, while it attacks their enemies.

The Spiderant pet, however, also has the ability to deal Elemental Damage to your enemies, depending on which direction you decide to take it. The Spiderant Countess ability allows the Spiderant to deal Corrosive Damage, while also surprising your enemies by attacking them from underground.

Master Skill Tree for Fl4k in Borderlands 3

The Master Skill Tree is focuses on working as a team with your pet. Abilities like Hive Mind and Shared Spirit allow you to share the damage Fl4k receives with your pet, while Psycho Head On A Stick grants your pet increased Movement Speed after a kill.

Barbaric Yawp is an essential ability from this skill tree, because it will increase the power of all your pet bonuses. This is great if you've unlocked abilities like Go for the Eyes!, which makes your pet's first melee attack an automatic Critical Hit with increased Damage.

If you're a pet fan then this is the skill tree for you.

Like all of the Skags in Borderlands, Fl4k's pet Skag is focused on causing as much hard as physically possible. Great Horned Skag increases Fl4k's Gun Damage and gives the Skag the ability to knock enemies into the air.

The Skag can also gain the ability to regenerate its own health, thanks to the Mutated Defences ability. When the Skag is low on health, this ability will allow it to heal itself, with the only downside being that it will cause less damage.

What previous Vault Hunter is Fl4k like?

Fl4k remind us of Mordecai from the original Borderlands.

Mordecai also had an animal companion - the dangerous bird, Bloodwing. Using Mordecai's Action Skill, you can send Bloodwing flying at your enemies and he will attack multiple targets until his flight is finished.

Fl4k's beasts work in a similar fashion. You have the ability to let your pets loose on a group of enemies and can apply various upgrades to make them even more deadly. The Spiderant pet, for example, can be upgraded to deal Incendiary, fire, damage to nearby enemies.

What Fl4k has, which Mordecai doesn't, is a range of pets. This means if it turns out that you don't like the Jabber anymore, you can always reset your Skill Points and try out the Spiderant or the Skag.

If you're looking for the other character skills trees, then check out our Skill Trees guides for Amara, Moze and Zane.
