InOnce Human, Elemental-based builds such as the Burn build are among the most popular, providing players with a unique and customizable experience. By utilizing weapons, items, and gear that enhance your Burn-based damage output, you will cause enemies to take a damage-over-time status effect.

Inflicting this damage type on enemies means you can overpower the battlefield, but players have so many factors to consider, such as stacks, mods, the most complimentary Deviants, and more. Therefore, to bring your Burn build to its best potential, you must prioritize how each of these components can enhance Elemental Damage.

The Best Weapons For A Burn Build

Primary Weapon

TheKAM - Crankweapon is by far one of the best options as a primary firearm for a Burn build inOnce Human, as it excels at fighting bosses, due to its consistent and non-RNG-reliant Burn infliction. it also has excellent single-target DPS, and itdoesn’t require many enemies to hit to trigger the Burn effect.

Moreover, with this effect, comesincreased (+20%) Reload Speed, allowing you to continue taking enemies down quickly and faster, triggering the Burn effect again. The Kam Crank is also free, acquired from theMystical Crate inOnce Humanin Fort Eyrie in the Red Sands region, making it convenient to get for this build.

you’re able to bring theKAM - Crankto its best potential by equipping it with a Rapid Shot Style calibration. This will increase its fire rate by 15% and increase your Reload Speed by 40%. When fully calibrated, this feature also enhances the firearm’s weak point DMG, making it even more useful against bosses.

Secondary Weapon

A great secondary weapon choice for a Burn build inOnce Humanis theRecurve Crossbow. This weapon has garnered mass popularity and is considered to be theoverall best secondary weapon in the game, as it is adaptable to almost any build.

It caninflict enemies with the Bull’s Eye statuswhen targeting an enemy’s weak point, which synergizes well with the Rapid Shot style calibration. Your Crit Rate against enemies is increased, making opponents extremely vulnerable to your damage.

An alternative that could work for the Burn build, which has a similar effect to the Recurve Crossbow, is the D.E. 50 Wildfire Weapon from theWish Machine inOnce Human. It also inflicts the Bull’s Eye status, but only by a 60% chance, which is triggered when hitting any area of the target’s body. This option may be preferable, as you aren’t required to hit with precision compared to the crossbow, which must hit weak points.

The Best Mods For A Burn Build

Flame Resonance

The best feature about this mod inOnce Humanfor the Burn build, is that you aren’t losing as many stacks, so the Burn effect can continue for longer on a target, without being interrupted. Flame Resonance is a great alternative, which provides increased max Burn stacks by 2 but reduces Burn duration by 20%.

However, Ember is recommended, as you’re able to go from 70k DPS over time, to aminimum of 115k with this mod. The table below showcases all the best mods and their effects for the remainder of your gear for the Burn build setup, which is discussed further:

The Best Deviant For A Burn Build

Pyro Dino Or Lonewolf’s Whisper

While there are many Deviants that players can use for a Burn build, the best by far isPyro Dino. This exceedingly rare Combat Deviantbuffs Burn DMG against any target that it hits, by a significant amount. This is integral to the build, making your damage output all the more effective.

It is found in thesecret Seepage Zone in Silo Phi, but for those who haven’t gained access due to its rarity,Lonewolf’s Whispermakes a good option. This option is another offensive Deviant that, draws enemies away from players, which is helpful if you’re being crowded. You can get it after defeating Rabizex in the Monolith of Thirst.
