Killing Floor 3 Best Specialist Skills

Jump to a Class!
Commando IconCommando FirebugFirebug Medic IconMedic
Engineer IconEngineer Ninja IconNinja Sharpshooter IconSharpshooter

Commando (Foster)

Tool Rating Explanation
Killing Floor 3 Fire SaleFire Sale ★★★★★ Commando assault rifles consume ammo at a high rate, so having extra ammo capacity and cheap ammunition from the Trader is a great quality-of-life change.
Killing Floor 3 Preferred CustomerPreferred Customer ★★★★☆ Allows you to have a leg up during the mid-game as you can access stronger weapons earlier. Furthermore, this allows you to support the team by having more Dosh to spend on your Sharpshooter or Medic.
Killing Floor 3 A Real RagerA Real Rager ★★★☆☆ Allows the Commando to push during emergencies when there is an objective or ZED to focus on by using his Syringe.

Fire Sale and Preferred Customer Stabilizes Economy

While not as apparent as other skills that increase damage or stats, having the means of stabilizing your economy and sharing it with the team is key in the higher difficulties. For example, having access to tier 3-4 weapons before Scrakes and Fleshpound start spawning is a big deal, as it is an early swing.

A Real Rager Shines During Pushes

When you are trying to push through a horde of ZEDs to secure a point where your squad can camp or trying to complete a specific quest or objective, the "A Real Rager" perk will come in clutch!

Best Commando (Foster) Builds and Skills

Firebug (Devlin)

Tool Rating Explanation
Killing Floor 3 Unknown Skill IconHotfoot ★★★★★ Firebug requires a means of self-sustenance to excel in higher difficulty content. With Hotfoot, the Firebug can easily heal themself by standing in their flames
Killing Floor 3 Too Hot to HandleToo Hot to Handle ★★★★☆ Allows the Firebug to be slippery when they are getting swarmed by lesser ZEDs.
Killing Floor 3 Focus FireFocus Fire ★★★☆☆ Further increases the Firebug's damage capabilities by adding a percentage increase for direct hits, which works especially great for Boss clearing!

Hotfoot and Too Hot to Handle for Survivability

The Firebug already has enough firepower to mow down any ZED in her way, so the best skills for her would be the ones that increase survivability and utility. Too Hot to Handle lowers the cooldown of its defensive utility, while upgrading Hotfoot increases the passive healing received when standing in ground fire.

Focus Fire for Damage Boost on Direct Hits

To turn the Firebug into a worthwhile class during boss fights, Focus Fire is included. This skill maximizes the powerful direct-hit Heat damage of your main weapons, that being the Vulcan TA and Dragon's Breath!

Best Firebug (Devlin) Builds and Skills

Medic (Obi)

Tool Rating Explanation
Killing Floor 3 Social DistancingSocial Distancing ★★★★★ Having the ability to revive teammates from afar is a great boon to any Medic role for cooperative shooters, as it allows you to avoid risking your position for a revive. Upgrading this skill makes the resurrect even faster!
Killing Floor 3 SymbiosisSymbiosis ★★★★☆ With Symbiosis, it allows the medic to sustain itself while avoiding the use of your syringes or throwables. Each upgrade strengthens the heals you receive upon healing an ally.
Killing Floor 3 Stronger PerscriptionStronger Perscription ★★★☆☆ Healing is the Medic's core skill, so increasing its efficacy with Stronger Perscription should be a no-brainer!

Social Distancing and Stronger Prescription for Better Heals

Being the Medic, Obi is assigned to look after and minimize the squad's mistakes. With Social Distancing and Stronger Prescription strengthened, your heals and resurrects will be more reliable and applicable from a farther range.

Symbiosis for Self-Sustain

Seeing as there are limited ways for the Medic to heal themself, having Symbiosis allows you to independently sustain yourself by healing allies with your darts. It will be hitting two birds with one stone!

Best Medic (Obi) Builds and Skills

Engineer (Imran)

Tool Rating Explanation
Killing Floor 3 Unknown Skill IconReforge ★★★★★ Allowing the Engineer to support the squad while replenishing charges for his power suit is undeniably strong due to the value it generates.
Killing Floor 3 Unknown Skill IconMan Of Steel ★★★★☆ With Man of Steel, the Engineer will be much more sturdy armor-wise while staying slippery during hordes, as you cannot be grabbed by lesser ZEDs.
Killing Floor 3 Unknown Skill IconMajor Damage ★★★☆☆ Major Damage is a two-in-one package for the Engineer as it provides a decent damage boost while also increasing its crowd control potential.

Reforge Incentivizes Utility

Reforge allows you to restore gadget activation energy, which lowers Sonic Storm's cooldown when using a tool. This means that with Reforge, it is incentivized to provide advantages for your team by essentially increasing your uptime with your powersuit.

Man of Steel and Major Damage for Survivability

Both Man of Steel and Major Damage are generally the best-in-slot skills for Engineer when it comes to the class's survivability, as they are simple stat increases with extra assets sprinkled in.

Not only will you receive a damage and armor boost, but you cannot be grabbed by lesser ZEDs, and your shots will have higher stagger potential.

Best Engineer (Imran) Builds and Skills

Ninja (Nakata)

Tool Rating Explanation
Killing Floor 3 UnyieldingUnyielding ★★★★★ Easily the best skill for Ninja as it provides both a damage boost and self-sustained healing just by doing what the Ninja does best: cut down ZEDs.
Killing Floor 3 Dead CalmDead Calm ★★★★☆ Dead Calm is essentially a permanent damage boost, seeing as it is efficient to actively use Grappling Hooks to pass through and clear fodder ZEDs.
Killing Floor 3 KenkoKenko ★★★☆☆ The best part about the Kenko skill is that it gives you higher HP and is accessible early on. Additionally, you can heal yourself by performing perfect parries.

Unyielding and Kenko Make the Ninja Independent

Unyielding and Kenko allows the Ninja to go for risky plays that only they can be capable of due to the tankiness and independent healing these skills provide. If the Ninja is played perfectly, this set of skills will always keep the Ninja's high health pool tapped out with parries.

Dead Calm is a Permanent Damage Buff

Dead Calm boosts your damage by a significant amount when your Hebi-Ken shots are depleted, which should always be the case as the Grappling Hooks are meant to give the Ninja better horde clear with the pass-through mechanic, so that he has more space when fighting against Large ZEDs.

Best Ninja (Nakata) Builds and Skills

Sharpshooter (Luna)

Tool Rating Explanation
Killing Floor 3 Big ShotBig Shot ★★★★★ As a Sharpshooter, targeting ZED weak spots is your greatest strength since your weapons heavily prioritize critical damage. This lets you eliminate medium and large ZEDs much quicker.
Killing Floor 3 Chilling EffectChilling Effect ★★★★☆ The freeze from your Cryo Bomb is the Sharpshooter's only means of crowd control, so having them last longer is key for Luna's survivability
Killing Floor 3 Flight ResponseFlight Response ★★★☆☆ Repositioning is key as a Sharpshooter, so Flight Response grants additional movement speed during sticky situations where you are being outnumbered.

Big Shot Enhances the Sharpshooter's Game Plan

As a Sharpshooter, targeting the ZEDs from afar is your role for the team, essentially tasked to take out the hard-to-reach ZEDs such as Husks and Sirens. These two ZEDs have prominent weak spots, so Big Shot allows you to, on average, kill them with one shot!

Flight Response and Chilling Effect for Survivability

Apart from killing high-profile ZEDs, the Sharpshooter should always mind their general safety, as their range is important for the team. Whenever you are out of position or are just being swarmed by multiple ZEDs, the skill combo of Flight Response and Chilling Effect allows you to get out with fewer casualties suffered.
