## Crafting & Recipes
Crafting information lives on the **output item's YAML file** via the `craft:` block. There is no
separate recipe directory. To find out how to make `bronze_dagger`, open
`data/items/equipment/bronze_dagger.yaml` and look for the `craft:` block.
**The filename is the ID** (`bronze_dagger.yaml` → `bronze_dagger`). Ingredients reference items by
filename. The output item IS the craft — no separate `output` field.
### Craft YAML Reference
| Field | Type | Description |
|-------|------|-------------|
| `type` | string | Skill name: `smithing`, `cooking`, `crafting`, `fletching`, `pharmacy`, `construction`, or `""` for skill-less. |
| `subtype` | string | Production method override: `smelt` for furnace, `clean` for herb cleaning. |
| `level` | int | Required skill level |
| `xp` | int | XP awarded on success |
| `ticks_per_cycle` | float64 | Ticks per craft cycle |
| `station` | []string | Station object IDs required (e.g. `[anvil]` or `[furnace]`) |
| `tool` | string | Required tool_type (e.g. `knife`, `saw`). Tool is NOT consumed. |
| `ingredients` | []IngredientEntry | Ingredients consumed (see below) |
| `output_qty` | int | Quantity produced per cycle (default 1) |
| `fail` | string | Item ID produced on failure |
| `success_message` | string | Success message per cycle (%n, %i1, %i2, %b1, %b2) |
| `fail_message` | string | Failure message; empty = silent fail |
| `start_message` | string | Message when action begins |
| `end_message` | string | Message when action completes |
| `steps` | []CraftStep | Multi-step messages at tick offsets |
| `success` | SuccessFormula | Optional skill check formula (base, per_level, cap) |
### Message Variables
| Variable | Expands to |
|----------|-----------|
| `%n` | Output item name (colored) |
| `%i1` | 1st ingredient's matched item (colored) |
| `%i2` | 2nd ingredient's matched item (colored) |
| `%b1` | 1st ingredient's byproduct name (colored, success only) |
| `%b2` | 2nd ingredient's byproduct name (colored, success only) |
Numbering follows YAML ingredient/byproduct order. If an ingredient entry has multiple
alternatives (`items: [a, b]`), the variable expands to whichever the player has. Inline
color tags (`{C4}text{/}`) work alongside these variables.
### Message Defaults
If a message field is omitted, the game uses a skill-level default:
| Type | Default success_message | Default start_message |
|------|------------------------|----------------------|
| `cooking` | `"Cooked to perfection. %n looks great!"` | `"You start cooking %i1."` |
| `smelt` (subtype) | `"You remove a white hot %n!"` | `"You place the %i1 into the furnace."` |
| `smithing` | `"You smith a %n."` | `"You begin smithing %i1."` |
| `crafting` | `"You craft a %n."` | `"You begin crafting %i1."` |
| `fletching` | `"You fletch a %n."` | `"You begin fletching %i1."` |
| `pharmacy` | `"You mix a %n."` | `"You start mixing %i1."` |
| `construction` | `"You construct a %n."` | `"You begin constructing %i1."` |
| `clean` (subtype) | `"You clean the %i1."` | `"You begin cleaning herbs."` |
| (unset) | `"You produce %n."` | `"You start <verb> %i1."` |
For skills that never fail (smithing, crafting, fletching, pharmacy, construction),
`fail_message` defaults to empty — no message on failure.
### IngredientEntry — Multi-Item Ingredient Slots
Each ingredient entry defines a slot with multiple valid alternatives. The first matching
item in the player's inventory is consumed.
```yaml
ingredients:
- items: [item_id, alternative_id, ...]
quantity: 1
byproducts: [byproduct_for_item, byproduct_for_alt, ...]
```
`byproducts` matches the `items` list by index. Use `""` for items with no byproduct:
```yaml
ingredients:
- items: [bucket_of_water, vial_of_water]
quantity: 1
byproducts: [empty_bucket, ""] # bucket returns empty, vial is consumed entirely
- items: [herb]
quantity: 1 # no byproducts — herb is consumed entirely
```
### CraftStep — Multi-Step Messages
Interim messages fired at specific tick offsets during the cycle:
```yaml
craft:
type: ""
ticks_per_cycle: 6
ingredients:
- items: [map_piece_1]
quantity: 1
- items: [map_piece_2]
quantity: 1
- items: [map_piece_3]
quantity: 1
steps:
- tick: 1
message: "You try to puzzle how the pieces fit together."
- tick: 3
message: "Aha, this edge lines up here!"
success_message: "You assemble the map!"
```
### Skill-Based Production
```yaml
# data/items/consumables/stim_potion.yaml
name: stim potion
craft:
type: pharmacy
level: 3
xp: 25
ticks_per_cycle: 4
ingredients:
- items: [guam_potion_unf]
quantity: 1
- items: [eye_of_newt]
quantity: 1
success_message: "You mix a %n."
```
### Station-Based Production
Furnace (smelting):
```yaml
# data/items/materials/bronze_bar.yaml
name: bronze bar
craft:
type: smithing
subtype: smelt
level: 1
xp: 6
ticks_per_cycle: 4
station: [furnace]
ingredients:
- items: [copper_ore]
quantity: 1
- items: [tin_ore]
quantity: 1
fail_message: "You fail to smelt a usable bar."
```
Anvil (smithing):
```yaml
# data/items/equipment/bronze_dagger.yaml
name: bronze dagger
craft:
type: smithing
level: 1
xp: 12
ticks_per_cycle: 4
station: [anvil]
ingredients:
- items: [bronze_bar]
quantity: 1
```
Stackable outputs use `output_qty`:
```yaml
# data/items/ammo/bronze_nails.yaml
name: bronze nails
stackable: true
craft:
type: smithing
level: 4
xp: 12
ticks_per_cycle: 4
station: [anvil]
ingredients:
- items: [bronze_bar]
quantity: 1
output_qty: 15
```
### Tool-Based Production
```yaml
# data/items/ammo/arrow_shafts.yaml
name: arrow shafts
craft:
type: fletching
level: 1
xp: 5
ticks_per_cycle: 3
tool: knife
ingredients:
- items: [logs, oak_logs, willow_logs]
quantity: 1
output_qty: 15
```
### Skill-Less Combinations
Omit `type` (or leave empty) for combinations with no skill check and 100% success:
```yaml
# data/items/consumables/bucket_of_water.yaml
name: bucket of water
craft:
ticks_per_cycle: 0
ingredients:
- items: [vial_of_water, jug_of_water]
quantity: 1
byproducts: [empty_vial, empty_jug]
- items: [empty_bucket]
quantity: 1
success_message: "You pour the %i1 into the %i2."
```
### Multi-Piece Assembly
```yaml
# data/items/quest/ancient_map.yaml
name: ancient map
craft:
ticks_per_cycle: 0
ingredients:
- items: [torn_page_1]
quantity: 1
- items: [torn_page_2]
quantity: 1
- items: [torn_page_3]
quantity: 1
steps:
- tick: 1
message: "You try to puzzle how the pieces fit together."
- tick: 3
message: "Aha, this edge lines up here!"
success_message: "You assemble the %n."
```
### Clean Recipes (Herb Cleaning)
Use `type: pharmacy` with `subtype: clean`:
```yaml
# data/items/materials/guam.yaml (clean herb)
name: clean guam
craft:
type: pharmacy
subtype: clean
level: 3
xp: 3
ticks_per_cycle: 2
ingredients:
- items: [grimy_guam]
quantity: 1
```
### Food / Healing
Items with `heal_value` and `eat_message` can be consumed via the `eat` command. See
`items.md` for the full food item format.
### Construction
`type: construction` recipes use `station: [workbench]`. Log-to-plank recipes additionally
require `tool: saw`. See `construction.md` for plank tiers, furniture, NPCs, and player
housing.
