Alchemy

Branch: alchemy

Alchemy is Graveyard Keeper's most mechanically deep crafting system. Before any item can be used alchemically, the player must first study it at the Study Table, which reveals its decomposition products. Every item in the game decomposes into one or more of three forms: powders, solutions, or extracts. Each form is processed by a different dedicated machine: powders come from the Alchemy Mill, solutions from the Hand Mixer, and extracts from the Distillation Cube. This three-machine decomposition pipeline is the foundation of all alchemy and means the player must invest in all three stations and their tech unlocks before complex recipes are accessible. Unlocking the Scientist perk causes every machine to yield one extra decomposition product per item processed, making it an important mid-game milestone. Once the player has zombies unlocked, an Alchemy Decomposer zombie station becomes available that can produce all three forms simultaneously from a single item input, consolidating the pipeline and freeing the player from individually operating each machine. The Alchemy Workbench is the final assembly station. It exists in at least two tiers. The Tier I workbench takes a powder in the left slot and a solution in the right slot to produce a potion or component. Recipes must be entered left-to-right in the order displayed — the slot layout is fixed and cannot be skipped. The note in the wiki records: "It is not possible to craft recipes from the Tier I workbench and leave the third slot empty" — the Tier II workbench adds a third input slot for extracts, enabling higher-complexity recipes. Building the Tier I Alchemy Workbench requires 6 Wooden Planks, 3 Complex Iron Parts, and 2 Advanced Conical Flasks, and requires completion of the "Anatomy and Alchemy" tech branch. The recipe output ranges from healing and utility potions to body-treatment injections used in the morgue. Key Tier I outputs include: Heal Potion (Health Powder + Chaos Solution, restores 50 HP), Speed Potion (Acceleration Powder + Chaos Solution + Blood, increases movement speed), Digestion Potion (increases energy gain from food), Restoring Potion (slowly restores health), Zombie Juice (Health Powder + Blood, used in zombie crafting), and Growth Enhancer (Ash + Life Solution, used in farming). The workbench also produces all paint colors needed for grave decoration — Brown, Blue, Dark Green, Green, Dark Violet, Violet, Red, and Yellow — making alchemy a prerequisite for maximizing burial quality scores. Higher-tier workbenches unlock Silver Elixir and Golden Elixir for the morgue's injection system: Silver Elixir adds +1 White Skull and removes -1 Red Skull from a body, while Golden Elixir adds +2 White Skulls and removes -2 Red Skulls, directly influencing burial quality. Alchemy consumes blue tech points for most of its tree and is the primary driver of blue-point spending in the mid-to-late game. The strong coupling between alchemy and both the study table (faith cost) and the morgue (body quality) makes it an investment that cascades benefits across multiple systems simultaneously.
