A fresh zombie in Graveyard Keeper 2 is useless on its own. Drop one at the Woodworking Workbench, queue up a stack of planks, walk away, and you will come back to a corpse standing perfectly still. That is not a bug. Every zombie starts with 0 Work Mastery, and Mastery is the gate that decides which recipes a worker is allowed to touch.
Quick answer: Equip the zombie with a tool that matches the job. Inspect it, open the Character tab, and slot in an axe, hammer, shovel, pickaxe, or fishing rod. Better tools grant more Mastery.
Zombie Work Mastery: What the number actually gates
Each recipe at each station lists a Mastery requirement next to its ingredients, exactly like the requirements on your own Keeper. If the zombie assigned to that station does not meet the number, the job sits in the queue and the interface flags that the worker lacks the required tool.
Mastery on a zombie does not come from experience or from grinding. It comes almost entirely from what is in its hands. A rusty tool contributes +1 Mastery; bronze-tier gear and above contribute +2 or more. Swap the tool and you swap which category of work the zombie qualifies for, which is why the same corpse can make wooden planks in the morning and bronze nails after you hand it a hammer instead of an axe.
Which tool to equip for each job
Tool type has to match the station. General Mastery does not carry over, so a hammer will never get logs sawed no matter how high the number climbs.
| Work type | Tool to equip |
|---|---|
| Crafting and woodcutting | Axe |
| Metallurgy | Hammer |
| Farming | Shovel |
| Mining | Pickaxe |
| Fishing | Fishing Rod |
| Transport and courier duty | None required |
Transporter zombies are the exception. They do not use stats or tools at all, so park your weakest bodies at a Porter Station or the Zombie Supplier Station and save the geared ones for crafting benches.
How to equip a zombie and put it to work
Courier zombies cannot leave their work zone. The yard, garden, vineyard, brewery, science lab, and kitchen each need their own porter, and chests are zoned the same way. Moving goods between areas is still your job.
Craft better tools to raise Mastery further
Rusty starter gear runs out of headroom fast. Bronze is the first real upgrade, and everything in that tier is made at the Wooden Anvil. Later, the Iron Anvil converts the same tools into iron versions, which push Mastery higher again.
| Tool | Unlock requirement | Recipe |
|---|---|---|
| Bronze Axe | Metallurgy Mastery 2 | 2 Stick, 2 Bronze Detail, 1 Bronze Ingot |
| Bronze Pickaxe | Metallurgy Mastery 2 | 2 Stick, 2 Bronze Detail, 1 Bronze Ingot |
| Bronze Hammer | Metallurgy Mastery 2 | 2 Stick, 2 Bronze Detail, 1 Bronze Ingot |
| Bronze Shovel | Metallurgy Mastery 2 | 2 Stick, 2 Bronze Detail, 1 Bronze Ingot |
| Bronze Tools | Metallurgy Mastery 3 | 2 Stick, 1 Polished Bronze, 4 Bronze Detail |
Those unlock requirements apply to your own Metallurgy Mastery, not the zombie’s, so you need the Tech Tree progress before any of this gear exists. Once it does, a single crafting session can upgrade your entire workforce.
Perks: the second source of Mastery
Tools get a zombie off the ground. Perks are what let it stop being a bronze-only laborer. Working generates Red, Green, or Blue Gems depending on the task, and at 50 Gems a zombie can spend them on its first Perk.
- A Perk can raise one chosen stat by 1, which unlocks higher-level recipes at that station.
- Specialized Perk lines go deeper, with woodworking reaching a +4 bonus when working with wood.
- Red Skulls set the ceiling: the count determines the maximum number of Perks a zombie can ever unlock.
- Bronze Zombie Collars cap that ceiling at 5 Red Skulls, so upgrading the collar matters for long-term workers.
Perks are not awarded automatically. Inspect your workers now and then and spend the Gems, or they will sit on a pile of unspent points while stuck on low-tier recipes.
Raising the Red Skull ceiling at the Autopsy Table
Red Skulls run opposite to burial quality. Bodies you intend to bury want White Skulls; bodies you intend to put to work want Red. Strip Red Skull body parts out of corpses headed for the graveyard, store them, and insert them into a worker candidate at the Autopsy Table to push its Perk ceiling up.
Existing zombies can go back on the table too. Replacing organs improves them after the fact, and a better Zombie Collar is swapped in from the same Character tab you use for tools.
Farming zombies need a shovel and a Gardener Stand
Farmers follow the same Mastery rule but use a different posting. Equip a shovel to boost the farming stat, then build a Gardener Stand at the garden blueprint table using 4 Wooden Planks, 2 Bronze Details, and 6 Bronze Nails, and place the zombie there.
It still will not plant anything until you tell it what to grow. Use the second tab of the garden blueprint table to build Tablets for specific crops, one per row. The zombie plants the matching seeds from the garden chests, harvests when the crop is ready, and deposits the produce back into a chest.
Tablets cost nothing and can be destroyed and rebuilt for a different crop, but harvest the row yourself first. A farmer zombie only interacts with the crop listed on the Tablet.
How to confirm the Mastery fix worked
Open the station the zombie is assigned to. If the Mastery requirement is now met, the warning about the missing required tool disappears from the recipe and the zombie begins working through the queue on its own, with finished goods stacking up at the bench or being carried off by a courier.
If it is still idle, there are only two things to check. Either the Mastery is short for that specific recipe, or the station has nothing to work with. Keep the courier paths clear, empty finished goods out of chests regularly, and top the chests back up with raw materials, because a full chest stops the chain just as dead as a missing axe.
