Graveyard Keeper 2 Zombie Mastery & Perks: Why Your Zombie Won't Work, and How to Level It Up
Your new zombie is standing at the bench doing nothing. That is not a bug: every zombie in Graveyard Keeper 2 starts with 0 mastery. This page explains how zombie mastery adds up, which tools to hand out, how perk points are earned, and how to spend a small red-skull budget on the perks that matter.

TL;DR — Get an idle zombie working
| Check | Fix |
|---|---|
| Mastery below the recipe's need | Give it the best tool for that mastery (+1 to +6) |
| Station needs a tool type | Axe, hammer, pickaxe or shovel in its hand |
| No materials arrive | Put a second zombie on a Zombie Supplier Station |
| Still short on mastery | Spend the zombie's own points on +1 mastery nodes and a job perk |
| No perk slots left | Add red skulls: organ swaps or a better collar |

How zombie mastery adds up
A zombie has the Keeper's five masteries: Building, Smithing, Farming, Book writing and Anatomy. For any recipe, its mastery is:
nodes it bought on that tree + the tool in its hand + a perk for that kind of work
- Normal recipes only start once that total reaches the recipe's requirement.
- Star recipes and autopsy tasks bypass the normal threshold and begin at mastery 1 or above.
- A zombie holds one tool or weapon and one armor, so pick the tool for its main job.
- Patch 1.005 made pending zombie crafts show when the skill level is too low. If a queued craft shows that warning, it is a mastery problem, not a broken bench.
Tools: the fastest mastery boost
Give every new zombie the best tool you own for its job. It works the moment you equip it.
| Mastery | +1 | +2 | +4 | +6 |
|---|---|---|---|---|
| Building | Rusty Axe / Pickaxe | Bronze Axe / Pickaxe | Iron Axe / Pickaxe | Steel Axe / Pickaxe |
| Smithing | Rusty Hammer | Bronze Hammer | Iron Hammer | Steel Hammer |
| Farming | Rusty Shovel, Basic Rod | Bronze Shovel, Amateur Rod | Iron Shovel, Advanced Rod | Steel Shovel, Pro Rod |
| Book writing | Primer, Bronze Talisman | Dictionary, Silver Talisman | Glossary, Golden Talisman | — |
| Anatomy | Butcher's Kit, Starter Alchemist's Kit | Surgeon's Kit, Alchemist's Kit | Master Surgeon's Kit, Good Alchemist's kit | — |
Watch the "tools" sets. Bronze tools give only +1 Smithing, Iron tools +2 and Steel tools +4. A plain Iron Hammer (+4) beats Iron tools (+2). Read the tooltip before you equip.
A shovel covers kitchen work, because cooking is Farming. Stations that need a specific tool are listed on the Zombies hub.
How zombies earn perk points
Zombies pay for their nodes with their own tech points, never the Keeper's:
- Crafting. A zombie earns tech points each time it finishes work on a station.
- Winning battles. Zombie fighters earn red tech points for won fights. Patches 1.006 and 1.007 both list this change. See how to get tech points for the Keeper's side.
- Watching (one creator's trick). A zombie placed in front of a machine the Keeper started gained about 3 points when the craft finished, even without the mastery to run it. It's slow, but it gets a new zombie its first node.
To spend points, Inspect the zombie and open its perk trees. The first node on every tree is a +1 mastery upgrade (50 points on Building, Smithing and Farming; 25 blue on Book writing and Anatomy), and almost every perk sits behind it. The one exception is the Musician line on Book writing.
| Tree | Nodes | Mastery from nodes | Whole tree costs | Paid in |
|---|---|---|---|---|
| Building | 17 | +9 | 4,600 | red |
| Smithing | 17 | +9 | 4,450 | red |
| Farming | 17 | +9 | 4,650 | green |
| Book writing | 19 | +9 | 1,500 red + 835 blue | red + blue |
| Anatomy | 15 | +9 | 1,500 red + 1,075 blue | red + blue |
Perk slots: one per red skull
Every node a zombie buys takes one red skull, mastery upgrade or perk.
- A zombie can purchase another node only when its red-skull count is higher than its current node count.
- If its red count later falls below its node count, some nodes stop working until it has enough again.
- White skulls give no slots.
So a 5-red zombie owns five nodes in total, across all five trees. Specialise: one zombie, one job. To add slots, put the zombie back on the autopsy table for red parts or swap in a higher collar. The steps are in build a 5 or 10 red skull worker. Golden collars need Smithing mastery 8 to craft; a soldier's stew gives +2 for a while.
Best perks by job
| Job | Tree | Perk (cost) | Effect |
|---|---|---|---|
| Woodworker | Building | Apprentice Carpenter (200) → Master Carpenter (500) | +2 / +4 Building with wood |
| Stonemason | Building | Novice Stonemason (200); Master Stonemason (500) | +2 with stone; +4 with marble |
| Quarry / lumber / digger | Building | Quarryman, Logger (200); Excavator (50) | 6 ticks instead of 8 |
| Smith | Smithing | Novice Blacksmith (100), Advanced Blacksmith (200), Master Blacksmith (500) | +2 bronze, +4 iron, +6 steel |
| Glass | Smithing | Puff Master (200) | +3 with glass |
| Miner | Smithing / Building | Zombie Miner (100); Magpie's Eye (500) | Ore in 6 ticks; 10% chance of a Gem |
| Factory | Building or Smithing | Factory Operative (500) | 2 fewer ticks on 63 recipes |
| Gardener | Farming | Dirt Digger (100), Crop Planter (500) | +2 / +4 when planting |
| Miller / kitchen | Farming | Miller (100) | Flour 8 instead of 5 at the Millstone |
| Brewer / wine | Farming | Brewer (200), Presser (200), Winemaker (500) | +3 brewery, +4 juice, +5 wine |
| Writer / printer | Book writing | Dead printer (25 blue), Dead King (25 blue), Dead press (100 blue) | More paper per craft; head start on Story and Newspaper; +3 at the Printing Press |
| Distiller / alchemist | Anatomy | Dead distiller (50 blue), Dead alchemist (50 blue), Zombie alchemist (100 blue) | More Melted Fat and Alcohol; chance of 1 extra item; +3 on potions |
| Grave builder | Anatomy | Dead grave builder (200), Grave architect (500) | 2 fewer ticks; +3 on gravestones and fences |
| Choir / Organ | Book writing | Novice → Skilled Musician → Maestro (10 / 25 / 50 blue) | Church quality 2 / 4 / 7 from that zombie instead of 1 |
| Fighter | Smithing | Impaler, Blindseye (200); Tin Can, Undead Resilience (400) | +2 pike / +3 bow damage; +1 armor; 150 health |
Costs are in red points unless marked blue or listed on the Farming tree (green).
Skip these: Wikily lists Novice Fisherman, Veteran Fisherman and Dead jeweler as having no effect. Also, several Book writing and Anatomy perks show +4 in the tooltip, but Wikily measures +3. Plan on +3.
Three example builds for a 5-red zombie
Five slots, five nodes. Start each tree with its 50-point +1 node.
Iron smith (550 red points)
- Smithing +1, Novice Blacksmith, Smithing +1, Smithing +1, Advanced Blacksmith.
- Result: +3 from nodes; with an Iron Hammer that's 7, or 11 when working iron.
Woodworker (650 red points)
- Building +1, +1, +1, Apprentice Carpenter, Building +1.
- Result: +4 from nodes, +2 with wood; with a Steel Axe that's 12 on wood recipes.
Gardener (550 green points)
- Farming +1, +1, Dirt Digger, +1, +1.
- Result: +4 from nodes, +2 when planting; with a Bronze Shovel that's 8 when planting.
A choir zombie only needs 3 slots for the Musician line, which pays 85 blue points in total. Singing isn't crafting, so let it earn its points on a crafting station first.
Suppliers and haulers: don't waste red skulls
A workstation zombie doesn't fetch its own inputs. A zombie on a Zombie Supplier Station brings materials to the workstation zombies in its area and clears finished goods into chests. It needs no tool and no perks, so give that job to a 0–1 red body. Porters and the factory follow the same idea; see supplier & factory roles.
One creator's early setup is one specialist per mastery you need, plus a carrier. That keeps you under your zombie limit, which cuts sermon rewards when you go over.
Troubleshooting
| Symptom | Cause | Fix |
|---|---|---|
| Stands idle at a bench | Mastery 0 or too low | Better tool, then +1 nodes |
| Idle at a quarry, digger or anvil | Wrong tool type | Pickaxe, shovel or hammer |
| Works once, then stops | No supplier, or the output is full | Add a supplier zombie; empty chests |
| Can't buy a node | Nodes already equal red skulls | Organ swap or higher collar |
| A perk stopped working | Red count fell below node count | Add red parts back |
| Kitchen zombie wastes ingredients | Old bug | Update; 1.006 fixed it |
FAQ
Q: How should I spend a zombie's first perk points?
A: Buy the first +1 mastery node for the tree that matches its job, then add a job perk when you have a free red-skull slot. Nodes use the zombie's own tech points.
Q: How do I increase zombie mastery?
A: Three ways add together: the tool in its hand (+1 to +6), mastery nodes it buys on its own trees (+9 in total per tree), and job perks such as Master Carpenter (+4 when working with wood).
Q: How do zombies get perk points?
A: They earn their own tech points while crafting, and red tech points for winning battles. They never spend the Keeper's points. Open the zombie with Inspect to spend them.
Q: How many perks can a zombie have?
A: One node per red skull on its body. Mastery upgrades and perks both take a slot. A 5-red zombie can own 5 nodes; if its red count later drops, some nodes stop working until it has enough again.
Q: Which zombie perks are useless?
A: Wikily lists Novice Fisherman, Veteran Fisherman and Dead jeweler as having no effect, because zombies do no fishing and the jeweler recipes come out the same. Skip them.
Q: Do supplier zombies need mastery or perks?
A: No. A zombie on a Zombie Supplier Station needs no tool and no perks, so a 0–1 red body is fine for that job. Save high-red bodies for crafting stations.
