Borderlands 3 FL4K Build: T0X1C M1ST FL4K [Level 65, Mayhem 11] + SAVE FILE

This Borderlands 3 FL4K Build bases on dealing the highest amount of damage by not doing too much. This is a pet build, that focuses on the radiation element. You will use your action skill. The pet will draw the attention of all the enemies. Thanks to the class mod they all will be taunted for the duration of your action skill. You can find this Borderlands 3 FL4K Save File at the bottom of the article.

Important! All the items are perfect rolls. If you do not want to download the file you can only gather inspiration for the build and try to replicate something similar in the game. The build contains gear from all the DLCs to Borderlands 3.

Borderlands 3 FL4K Build Explanation

Because you will be using either Deathless or Front Loader the health gate mechanic will not work for this build. Health gate is a mechanic that if your health drops below 50% of its maximum value then the damage is taken that would otherwise kill you is ignored. It is a mechanic to prevent frustration and unfairness from the game.

Your survivability relies on some of your skills and also you need to have your skill as often as possible. In this way, you will not be exposed to any danger because your pet will gather all aggro. You do not have to worry about the damaged output. The weapons included in this Borderlands 3 FL4K build are some of the most powerful in the game to help you survive while your action skill is still on cooldown.

I named this Borderlands 3 FL4K Build: “T0X1C M1ST FL4K” because of its huge focus on radiation damage and boosting this damage source by all means. I attached more aggressive and passive variants of the gear.
