Best Corrosion Build in Once Human

Corrosion Build Basic Info

The Corrosion Build is all about unleashing a relentless barrage of Power Surge! This build thrives on the chaotic synergy of stacking Power Surge and crits, allowing players to deal devastating damage consistently. At its core is the ACS12 - Corrosion shotgun, which perfectly embodies the build's essence, delivering shock damage that electrifies the battlefield. It's about making Power Surge go brrr!

Best Weapons for Corrosion Build in Once Human

Primary Weapon: ACS12 - Corrosion

The ACS12 - Corrosion shotgun is the lifeblood of the Corrosion Build (it was literally named after it), turning every shot into a potential party with a 70% chance to trigger Power Surge! This weapon doesn’t just deal damage; it amps up your crit game with a 15% Crit Rate boost.

When Power Surge triggers, it gives you a sweet 15% Crit DMG boost for six seconds, stacking up to ten times. Add in the 50% Psi Intensity damage that won’t decay over distance, and you’ve got a recipe for shocking destruction.

Here are the top attachments for your ACS12 - Corrosion to amp up your Corrosion build!

Secondary Weapon: Recurve Crossbow

The Recurve Crossbow the perfect match for the Corrosion Build, setting your foes up for a brutal finish! Nail those weak spots to inflict The Bull's Eye, which highlights the target and boosts your crit rate by 15% for 10 seconds. As if that wasn’t enough, marked enemies also take an extra 8% damage! It’s the perfect way to soften them up before unleashing your corrosion chaos!

Melee: Stun Baton

You'll want to get Stun Baton for the Corrosion Build. Here’s why: with a whopping 80% chance to inflict Power Surge with every light strike, you’re constantly ramping up that power. Once your target is electrified with Power Surge, landing a heavy strike doesn’t just pack a punch; it unleashes an extra wave of Shock damage to nearby enemies.

Best Armor for Corrosion Build in Once Human

Gas Mask Hood for Helmet

The Gas Mask Hood is a must-have for any Corrosion Build and Power Surge aficionado, cranking up your Crit Rate by 35% for 3 seconds right after you unleash that Power Surge! This means you can rain down critical hits like confetti at a party, stacking damage and making enemies wish they hadn’t crossed your path.

Lonewolf Set for Mask, Gloves, Shoes, and Bottoms

Equipping four pieces of the Lonewolf Set is like throwing a power-up party for your Corrosion Build! With a 10% increase in magazine capacity, you can keep firing without constantly reloading, allowing for more opportunities to trigger that sweet Power Surge.

The 5% boost to Crit Rate and the ability to stack Lone Shadow make your critical hits even deadlier. Each crit not only ramps up your Crit DMG by 6% but also increases your Crit Rate after a kill.

Bastille Jacket for Top

Grabbing just 1 piece from the Bastille Set is great for the Corrosion build because it gives you a solid +10% Weapon DMG boost as long as your HP stays above 70%. It's a simple but effective damage boost to stack on top of the Power Surge and crit bonuses.

Best Mods for Corrosion Build in Once Human

Best Weapon Mods

Shock Rampage for Primary Weapon

Shock Rampage is key for the ACS12 - Corrosion because it boosts your Power Surge trigger chance every time you deal Power Surge damage. With up to 4 stacks, you’re increasing the odds of Power Surge activating, allowing for more consistent procs of Power Surge damage and crits. Essentially, it fuels the build’s core loop—more Power Surges lead to more crits, which in turn amplifies your damage output.

All Mods List and Guide

Vulnerability Amplifier for Secondary Weapon

The Vulnerability Amplifier mod is always the perfect chocie for the Recurve Crossbow because it amplifies the effectiveness of The Bull's Eye by adding +8% Vulnerability to marked targets. This makes enemies take more damage, and since the Recurve Crossbow is all about hitting weak spots and stacking crits, the extra vulnerability ensures you’ll hit even harder when you follow up with your Power Surge weapons.

Shock Diffusion for Melee Weapon

The Shock Diffusion mod is a blast for the Stun Baton! When you trigger Power Surge, it zaps a nearby enemy with the same status, spreading the shockwave like a party favor. This means your heavy strikes will hit harder as you electrify more foes, turning each swing into a shocking good time!

Best Armor Mods

Deviation Expert for Helmet

With Deviation Expert, you get a 20% boost to Status DMG, making your hits land even harder. Plus, the 10% increase in fire rate means you can unleash damage faster, keeping the pressure on enemies. While the range reduction isn’t ideal, the offensive boosts make the mod worth it!

First Electrocution for Face

Boosting ultimate damage by 30% against enemies not in the Shock state is like throwing a surprise party for your foes!

Crit Amplifier for Gloves

The Crit Amplifier cranks up your crit game with a zesty 10% boost to Crit Rate and a spicy 15% increase in Crit DMG! It’s a perfect fit for this build’s crit-centric style

Covered Advance for Shoes

Taking no damage for 4 seconds nets you a hefty 20% damage boost for 30 seconds, letting you unleash a flurry of hurt while staying in the fight! What's not to like?

Rejuvenating for Top

Rejuvenating perfectly pairs with Covered Advance—take no damage to stack that sweet damage boost, then use those kills to recover health and keep the rampage going!

Deadshot for Bottoms

Deadshot is a slam dunk for the Corrosion build because it boosts your Crit DMG with every Crit Hit, stacking up to a whopping 45%! This means your corrosive blasts hit even harder, melting enemies faster—just the way we like it!
