The K&W MP6 will be the primary weapon you should prioritize upgrading, specifically before boss fight rounds. Alongside its fairly accurate and high rate-of-fire shots, the K&W MP6 can also equip the Healing Grenade launcher attachment to help with clearing hordes while healing a group of allies early on.

As per your boss fight weapon, the LF-85 will be the best option due to its strength in prolonged fights; the main reason being that it can regain darts as long as you are dealing damage to enemies.

For your sidearm, the Medic's default secondary KH-380 will serve you well, as having an extra source of healing during emergencies will come a long way. Furthermore, depending on the team composition, you can either go for recharging syringe darts or an upgraded burst-fire mode!

The Multi-Tool tool should be the best option to support your team, as the Medic's early game healing should suffice. However, if your team sustains early casualties, consider transitioning to the Syringe Bag on the second round!

Tier List Evaluations
Solo	▶︎ Nice clear but struggles with Large ZEDs
Squad	▶︎ Decent when with other Medics

Alternatively, if you wanted to play the Medic solo, the K&W MP6 is still the best option, albeit it should be kitted purely around damage and self-sustain. The MP6 has decent single-target damage while allowing you to self-heal with Symbiosis, which is especially potent with Healing Grenades as it damages and heals at the same time!

The Disciple sidearm then allows you to hit those pesky Husks and Bloats from a decent range, essentially covering the blaring weakness of a Solo Medic. As for your tool, the Syringe Back

As for the best skills, most have been changed simply by removing all of the extra utility that supports your team and instead focusing on patching up the Medic's lack of damage. Some key skill inclusions are Pill Mill, Strength in Numbers, Active Infection, and Terminal Diagnosis

Primary	Secondary

Best Medic Primary Weapons

Primary Weapon Slot 1

Primary	K&W MP6
Recommended Mods	Hollow Point Rounds Suppressed Barrel Healing Grenade Launcher Reflex Sight Lightweight Mag Fast Action Receiver

The K&W MP6 is the Medic's best and most versatile weapon, having the ability to mow down fodder ZEDs while having access to solid secondary attachment mods depending on the situation.

In terms of mod priority, the Healing Grenade Launcher attachment should be a no-brainer as it offers AoE healing and ZED debilitation. Furthermore, get the Hollow Point Rounds mod as the main role of the Medic is to clear Flesh-type enemies to create space for your Squad whilst healing.

Additionally, the weakness of the K&W MP6 is its high recoil and low damage-per-shot, so the other mods recommended here should serve as a means to improve on these weaknesses while enhancing the fundamental strengths of the gun.

Primary Weapon Slot 2

Primary	LF-85
Recommended Mods	Biomorphic Boosted Battery Penetrating Barrel Enhanced Foregrip Reflex Sight Secondary Battery Booster Overclocked Receiver

The LF-85 is the best choice for when you reach the boss round, often swapping out the K&W MP6 for it. Its main strength is that it can siphon the damage it deals to ZEDs to turn it into darts, meaning it will shine in long and drawn-out fights as the amount of healing you can dole out is only limited by your ammo and DPS.

For mod priority, the Biomorphic Boosted Battery will be a solid investment as it will improve your healing by giving it an overtime effect at the cost of ammo efficiency. With this, you have damage uptime while retaining the consistent healing the LF-85 provides.

Additionally, if you will be facing the Chimera or are lacking in the crowd-control department, you can opt to replace the Penetrating Barrel with the Cold Fusion Converter. This will allow you to take the role in clearing the fodder while healing your Squad.

Alternative Primary Weapons

1	Biomorphic Projector	Primary DMG: 70 Primary Fire Mode: Biological DMG Base Cost: 2,300
2	Fieldmaster HR-10	Primary DMG: 230 Primary Fire Mode: Ballistic DMG Base Cost: 1,400

Alternatively, the Biomorphic Project can be an effective choice if you plan on pocket-healing a Ninja or if you do not prefer the SMG playstyle. This weapon option also scales pretty well into the later parts of the game if you get the Confusion Additive mod for the confusion crowd control.

An effective off-perk option for mid-game Medics whose squad is lacking in terms of answering long-range ZEDs is the Fieldmaster HR-10. If your team does not have a Sharpshooter, this gun should be a budget yet effective option.

List of All Primary Weapons

Best Medic Sidearm Weapon

Sidearm	KH-380
Recommended Mods	Instant Heal Darts Muzzle Brake Laser Sight (Pistol) Reflex Sight (Pistol) Lightweight Mag Dart Recharger Kit

The KH-380, Obi’s default sidearm, is the best choice thanks to the sole fact that it has a separate ammo pool for Darts, making it ideal for emergencies where you need to expend a lot of healing. With the Instant Heal Darts and Dart Recharger Kit modifiers, this pistol can come in clutch!

Alternative Sidearm Weapons

1	Disciple	Primary DMG: 160 Primary Fire Mode: Ballistic DMG Secondary DMG: 250 Secondary Fire Mode: Ballistic DMG & Cold DMG Base Cost: 900

If your squad is lacking a Sharpshooter and you are on a very tight budget, the Disciple would be the better option for its precision and headshot damage. While it is not as fast to handle or shoot as the KH-380, its accuracy among the sidearms is unparalleled.

List of All Secondary Weapons

Medic Best Tools

Best Medic Tools

Tool	Effect
Multi-Tool	Multi-function tool with 3 charges. • Activates and allows remote enabling of Traps. • Enables Ziplines • Unlocks Armor Lockers and certain Doors • Repairs damaged Explosive Locks

The Multi-Tool is the best option for the Medic as it can open up advantageous situations and mobility with Ziplines for your squad.

Alternative Tool

	Tool	Effect
1	Syringe Bag	First-aid kit that provides the team with additional syringes. • 2 deployable bags • Each bag grants 1 syringe

The Syringe Bag is considered an alternative tool as the healing on the earlier parts of the game can be kept to a minimum, especially with the Medic. It would be best to swap into this during Boss fights, or if you plan to take the Doctor's Bag skill when going solo.

List of All Tools

Medic Bonus Ability Priority

Ability and Priority	Explanation
Each shot has 1.5% chance to deal 150% Damage. ★★★★★	The Medic makes full use of the Spray-n'-Pray playstyle due to their weapons mainly being SMGs with high magazine capacity and fire rate. Stacking up on this ability will surely increase your clear strength and consistency with activating your Chemical Reaction.
Teammates within 10m have a 5% chance to gain 5 Armor after killing an enemy. ★★★☆☆	As for the second recommendation, having the ability to provide Armor for your team will allow you to save up on your resources during the early game, giving you the chance to buy the higher-tier guns much earlier into the match.
Add 10 Panic Power. ★☆☆☆☆	Lastly, the additional Panic power will increase the likelihood of your Chemical Reaction to stay in place for your teammates to finish off. While not essential, it is a noticeable change in the higher levels!

For the Medic, it would be best to prioritize the following Bonus Abilities to make up for its miscomings in terms of damage and strengthening their utility by also adding the chance to provide Armor for your squadmates.

List of Bonus Abilities for Mods

Best Medic Skills

Jump to a Skill Type!
Passive	Throwable	Gadget

Best Medic Passive Skills

Level	Skill
Level 2	Healing Hands Base Effect: Ally revivals are 50% faster. ┗ Reviving allies heals them for additional 10 health.
Level 8	Stronger Perscription Base Effect: Weapon healing is increased by 15%.
Level 14	Symbiosis Base Effect: Healing allies with your weapon or hitting enemies with your weapon's healing effects heals you for 20% of your healing amount.
Level 20	Social Distancing Base Effect: Shooting down allies with your weapon's healing effects heals their bleed out health for 140% of your weapon's standard healing. ┗ Restoring their bleed-out health to full will revive them.
Level 26	Chemical Reaction Base Effect: Killing enemies with your weapon has a 15% chance to trigger a chemical reaction gas cloud that lingers for 5 seconds. ┗ The cloud heals allies over time and applies Panic and Toxic affliction to enemies. ┗Panic interrupts enemies, causing them to writhe in place helplessly. ・Toxic afflicts enemies with Biological damage over time.

The recommended Passive Skills for the Medic are designed to enhance the Specialist's healing ability. With this skill set up, the amount you heal will improve with Stronger Perscription and have better resurrects through the Social Distancing and Healing Hands combo.

Furthermore, skills such as Symbiosis and Chemical Reaction improve the sustainability of the Medic. Symbiosis allows you to heal yourself by a percentage of what you heal your teammates with, while Chemical Reaction can control a group of ZEDs if you need to reposition.

Passive Skills for Solo Build

Solo Medic Passive Skills
Doctor's Bag Lvl 2	Pill Mill Lvl 8	Strength in Numbers Lvl 20

When going for a solo Medic, replace all of the passives that enhance healing for your allies and instead focus on self-sustain, ammo efficiency, and additional damage. Furthermore, with the way the Symbiosis and Healing Grenade work, it essentially doubles the self-heal as it counts as healing.

Best Medic Throwable Skills

	Skill
Level 4	Gas Expansion Base Effect: Biotic Grenade gas cloud radius is increased by 15%.
Level 10	Capacity Increase Base Effect: Throwable carrying capacity is increased by 1.
Level 16	Anesthetist Base Effect: Biotic Grenade gas cloud applies 30 Enfeeble affliction every 0.5 seconds. ┗Enfeeble weakens enemies, causing them to move and attack more slowly.
Level 22	Capacity Increase Base Effect: Throwable carrying capacity is increased by 1.
Level 28	Lingering Cloud Base Effect: Biotic Grenade gas cloud durations is increased by 6 seconds.

The recommended Throwable Skills for the Medic is designed to turn the Biotic Grenade into either a means to set up ZEDs or as an emergency precaution for when you need to reposition.

The combo between Gas Expansion, Anesthetist, and Lingering Cloud will reliably enfeeble a massive group of ZEDs, essentially giving you and your Squad more leeway. The build purposely opted to leave out the healing skills as the Passive Skill Tree already provides sufficient healing.

Throwable Skills for Solo Build

Solo Medic Passive Skills
Cull the Weak Lvl 4	Active Infection Lvl 28

The Biotic Grenade is often just used for group healing; however, this skill set turns this humble healing apparatus into a throwable that can clear from the initial explosion while spreading the damage to other nearby ZEDs through its Infection mechanic.

Best Medic Gadget Skills

	Skill
Level 6	Health Benefits Base Effect: When Sanctum expires, it heals all allies within its radius for 25 health.
Level 12	Burn Unit Base Effect: Sanctum's energy field deals 100% increased damage over time to small enemies.
Level 18	Steroid Injection Base Effect: Allies within Sanctum's radius receive a buff increasing their weapon damage by 10% for 5 seconds.
Level 24	Storm Shelter Base Effect: Sanctum duration is increased by 5 seconds.
Level 30	Resuscitator Base Effect: Sanctum field expansion blast revives down allies and healls all allies within the blast radius for 20 health.

The recommended Gadget Skills for the Medic make the Sanctum into a haven for your squad but a death zone for ZEDs. Each skill has a different role and purpose depending on the situation:

Health Benefits - Heals all of the allies inside the Sanctum.
Burn Unit - Keeps out and kills the fodder ZEDs to secure space.
Steroid Injection - Incentivizes the whole team to stay in the Sanctum by increasing weapon damage.
Storm Shelter - Increases the duration of the Sanctum

Resuscitator - Acts as an instant group revive during dire situations.

Gadget Skills for Solo Build

Solo Medic Passive Skills

In terms of changes, replace Health Benefits and Resuscitator with the following to answer the Medic's lack of mobility with Muscle Stimulant while strengthening your clear capabilities with Terminal Diagnosis.

Medic Skill Priority

Medic Skill Upgrade Priority

Skill	Priority	Explanation
Social 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!
Symbiosis	★★★★☆	With Symbiosis, it allows you to sustain yourself while avoiding the use of your syringes or throwables. Each upgrade strengthens the heals you receive upon healing an ally.
Stronger Perscription	★★★☆☆	Healing is the Medic's core skill, so increasing its efficacy with Stronger Perscription should be a no-brainer!
Chemical Reaction	★★☆☆☆	While Chemical Reaction is strong, the additional percentage can be lackluster compared to the top three Medic skills.
Anesthetist	★☆☆☆☆	The Anesthetist base effect is already strong, so upgrading the slow to be much faster can be redundant.

Prioritize spending your points on leveling up Social Distancing first. Being the Medic, Obi is assigned to look after and minimize the squad's mistakes. With Social Distancing, Symbiosis, and Stronger Prescription strengthened, the margin for error is lessened for the squad as the Medic will be a reliable safety net!

Lastly, upgrading the Chemical Reaction and Anasthetist skills allow the Medic to set up situations more consistently through their crowd control, but are not that impactful with each upgrade. With this, prioritizing the three main skills mentioned above will strengthen the foundation of the Medic.

How to Play Medic

Medic Playstyle Tips
Be Resourceful With Heals Focus on Clearing Lesser ZEDs Use Sanctum to Divert Range Attacks Gain the High Ground

Be Resourceful With Heals

The Medic, while consistent with healing, has a limited pool of resources for recovery, unlike in other cooperative shooters. With that in mind, always be mindful of your Darts, Grenades, and Sanctum charges as this can make or break a mission.

A squadmate's HP should be in the 70-80% range to make the most value out of your heals. With that in mind, classes like the Ninja and the Engineer should be the main priorities in terms of healing, as they are constantly in the faces of ZEDs.

Focus on Clearing Lesser ZEDs

While you are led to believe that the Medic's only role will be healing, that is not the case in Killing Floor 3. The Medic for this iteration specializes in clearing out the Lesser ZEDs as they have easy access to the Biological Damage type, meaning that Clots and Gorefasts are easily dealt with.

Upon doing this, you give yourself and your squadmates more space and ease of mind to take out the high-priority ZEDs like Fleshpounds and Scrakes.

Use Sanctum to Divert Range Attacks

The new Sanctum tool for the Medic has diverse applications depending on the situation. The best way to use them is to heal up the whole group, but you can also use the Sanctum if your squad is having trouble with Husks and Sirens.

Not only does it completely nullify the projectiles of the Husks, but it also heals up the possible burst damage that a Siren's scream would deal.

Gain the High Ground

The best position for a Medic will always be the high ground, as it gives you a better vantage point and assessment of who is low on health, as well as what group of ZEDs would be best to throw your Biotic Grenades at.

Hello dear user, thank you for using our build guide as a reference! Based on our findings, it should be possible. However, if that is not the case, the next best thing would be to get the "Teammates within 10 meters gain 3% damage buff for three seconds after killing an enemy" bonus ability. Thank you and have a nice day
