While leveling for this build, it is recommended you focus your skill points on the Stalker Tree until unlocking the Unblinking Eye Augment. From there, level the Hunter Tree until fully leveling Two F4ng skill, then return to the Stalker Tree and level other skills until reaching the Power Inside.
Use Gunslinger Jabber for Pet
The Gunslinger Jabber will increase your Crit damage by 5% while active thanks to its passive skill. It can also dish out a fair amount of damage with its attack command rocket launcher, while staying out of the enemy's range.
Build Strengths
Extremely High DPS
FL4K is able to dish out insane amounts of damage, using the Fade Away action skill in conjunction with the modifiers. The critical damage dealt with the Stalker skills are further enhanced with the Hunter skills.
Pets Are for Solo & Utility
Since this build focuses on the kills & damages being dished out by FL4K, the pets are more of a utility in this build. Lick the Wounds skill can keep you up in solo play when in a tight situation.
Tips for the Build
Use Jakobs & Vladof For High DPS
Thanks to the Guerrillas in the Mist modifier, your action skill's crit buff can be utilized even while using rapid fire weapons. High RoF weapons such as Vladof & Jakobs guns can clear enemies with little effort.

Thanks to its weapon brand perk, Jakobs shotgun can clear crowds with its ricochets. Try using a high pellet count shotgun for maximum crowd clearing capabilities. Try to funnel enemies into a choke point or narrow path for maximum effect.

Build Overview
Turn your pet into a walking nuclear bomb with this build! With a focus on increasing the damage and survivability of both FL4K and their pet, this build will have you melting through your enemies with every Action Skill use.
Focus on Master Skill when Leveling Up
As you level up, sink your Action Points into the Master Skill to get the build's Pet and Augmentation Skills. Once you've unlocked those, you can move on to filling out the Stalker Skill Tree.
Build Strengths
High Damage while Also Being Tanky
Putting emphasis on both damage and tankiness, this build will have you dishing out damage as much as you can take them. This goes for both FL4K and their pet!
Strong Emphasis on Radiation
Radiation is the jack-of-all-trades of the elemental types meaning it will work against most enemies bar shielded and radioactive ones. It's easier to use as well since it's an Aura damage type.
Tips for the Build
Always Have a Shock Weapon
Since Radiation's major weakness is shields, it's necessary for this build to always have a Shock weapon. You can also use Shock Weapons to deal with Radioactive enemies.
Use Gamma Burst to Revive Pet
You can use your Gamma Burst to immediately revive your Pet. The skill will summon them with full health along with the Radiation Aura!
Can Also Work with Emphathic Rage
If you want to deal more damage as FL4K, you can also opt out the Endurance Augmentation for Emphathic Rage. This will increase your damage during the duration of Gamme Burst.

For the first half of your playthrough, you'll need to invest all of your Skill Points to the Stalker Tree. Once you get to the Guerillas in the Mist Skill Augment, move on to filling out the Master Skill Tree for the Pet Buffs.
Use Gunslinger Jabber or Eridian Skag for Pet
Depending on your preference, you may choose either the Skag or the Jabber for this build to work. The Gunslinger Jabber can lay extra fire support with his rocket launcher attack command and Eridian Skag can pull in enemies nearby for easier crit-chains with a Jakobs gun.
Build Strengths
High Damage Build for FL4K
With the multiple critical damage buffs in the Stalker Skill Tree, this build amps up how much damage FL4K can do when using his Actions Skill and beyond that!
Offensive & Defensive Support from Pet
This build is a perfect middle ground for Pets wherein they give both offense and support. When in Fight For Your Life, your pet can revive you by either killing an enemy or going to you to revive you.
Tips for the Build
Use Jakobs Weapon for Crit Damage & Chain
Most of the Stalker skills are centered around boosting critical damage. Jakobs weapons are great for this since they have some of the highest critical multipliers in the game and chain damage when you crit.

The Guerillas in the Mist will allow you to continuously shoot enemies without ending your Fade Away. Use Vladof weapons for their fast fire rate to continuously get critical hits of enemies while cloaked.

FL4K can summon a pet as a companion in battle at any time. They can choose from a melee-based Skag, a Jabber with a gun, or a support Spiderant.
Greatly Buffs Critical Damage
With more emphasis on critical damage than other Vault Hunters, FL4K makes for a great Sniper. Although this requires for more careful shots.
