Project Zomboid First Aid Kit & Skill Leveling Guide

Project Zomboid First Aid Kit & Skill Leveling

The First Aid Kit is a portable medical container - it holds bandages, disinfectant, suture needles, and painkillers in one stack. The First Aid skill is what makes those items work better. This guide covers both: how to use the kit, and how to level the skill efficiently.

Using the First Aid Kit

The Kit is a container, not an active item. It holds:

• Bandages, sterilized bandages
• Bottle of Disinfectant, alcohol wipes, cotton balls
• Suture needles, regular needles, thread
• Painkillers, antibiotics, vitamins
• Splints, ripped sheets, comfrey poultice

To treat a wound: open the Health panel (hotkey H), right-click the wound, and select the appropriate item from anywhere in your inventory or the kit. Items in the kit count as part of your carried inventory for treatment purposes.

What the First Aid Skill Does

Higher First Aid skill levels improve every medical interaction:

• Faster treatment animations - apply a bandage in fewer in-game seconds.
• Bandages last longer before going dirty.
• Splints heal fractures faster - each level adds an additional 5× healing rate factor.
• Better wound diagnosis - the Health panel shows clearer information on infection severity.
• Poultices last longer when applied.

How to Level First Aid Fast

First Aid XP comes from treating wounds - yours or another player's. Pure self-healing from a single bite gives almost no XP; you need a steady stream of injuries to grind. Three reliable methods:

Method 1 - The "Glass Window" Trick

1. Find a window with shards of glass still in the frame (not cleared).
2. Climb through it. You'll take a non-zombie laceration on your arms.
3. Treat it with disinfectant + bandage for First Aid XP.
4. Repeat. Non-zombie lacerations have 0% Knox infection chance, so this is safe in a controlled environment.

Method 2 - Sprinting Through Trees

Run through a forest while sprinting. Branches inflict scratches at no zombie infection risk. Bandage each, gain XP. Slower but sustainable for hours.

Method 3 - Multiplayer Field Medic

On a server, treat your teammates' wounds. You get the XP, they get the bandage. The First Aid for Dummies magazine (in pharmacies, hospitals, doctor offices) gives a passive XP boost while in your inventory.

What to Put in the Kit, by the Numbers

Read from the shipped files of the Build 42 Stable server we run (build 24909836). Bandage power is the game's own stat for how much a dressing does.

Two things fall out of this. Denim and leather strips are the worst thing you can carry, double the weight of ripped sheets for identical power, so tear sheets instead and save the leather for clothing armour. And a dirty dressing is worth one eighth of a clean one. Build 42 tags every dirty dressing as washable and reusable, the bandage, the ripped sheets, the denim and the leather alike, so a trip to a water source turns 0.5 back into full strength rather than costing you a fresh bandage. Washing is a supply line, not a nicety.

Watch the Weight of Boxes

Build 42 ships box variants of the medical items, and they are heavy: Base.BandageBox, Base.AdhesiveBandageBox and Base.SutureNeedleBox all weigh 1.0, which is ten times a single bandage at 0.1 and ten times a loose suture needle, also 0.1. Loot the box, then break it down and carry the contents. The loose suture needle is tagged as fitting in a wallet, so it costs you almost nothing to keep one on your person.

Antibiotics and the Herbs

Antibiotics (Base.Antibiotics) carry an infection-reduction power of 50, weigh 0.1, and are flagged as medical. That value is identical in Build 41 and Build 42, so nothing about it changed with the update.

The three poultices, Comfrey, Plantain and Wild Garlic, each take 60 seconds to craft and each one must be learned before it appears in your crafting menu. Read the Herbalist magazine or take the trait. Drying is the slow one: all 25 drying recipes in the build share a length of 86,400, against 500 to 600 for ordinary crafting, so set it going and walk away. Common Mallow keeps its tea property through drying, so nothing is lost by doing it.
