Once Human Burn build guide: BiS gear, Deviant, and more

The Burn build in Once Human specializes in applying a strong Damage-over-Time effect on enemies, steadily reducing their health even while reloading your weapon or focusing on different targets. While it's not as good as the Shrapnel build in PvE, it's extremely fun to play and capable of soloing any content in the game, except Prime Wars. This makes it one of the top builds in Once Human.

This guide covers everything to know about the Burn build in Once Human, including the best weapons, armor sets, Deviant, and Cradle Override nodes.

Craft Tier 5 weapons and calibrate them to +10 at an Advanced Workbench for maximum damage output. Additionally, change the Calibration Attribute using the mentioned Calibration Blueprint.

The Recursive Crossbow is only part of this build due to its Bull's Eye debuff, which increases your Crit Rate on all weapons by 30 percent for 10 seconds and applies Vulnerability to the target. So, use this Crossbow first and then swap to your Legendary LMG in battle to deal the maximum damage on enemies.
