 - **Level**, **Health**, **Attack**, **Defence**, **Action points**, **Experience** — the battle numbers of the character. When the character has `Stats` (from the Stats Engine), **Health**, **Attack** and **Defence** are read-only: the stats compute them, and the form shows the computed values under the fields (see the party block below).
 - **Recruit chance** — 0 to 100: the chance to capture the character after beating it (see Recruiting).
 - **Behaviour** and **Actions** — how the character fights and which battle actions it has.
+- **Loot** — what drops when the character is defeated as an enemy: a list of rows, each with an item (a picker of the items the game knows), a minimum and a maximum count and a chance from 0 to 100.
 - **Fields of other mods** — fields other mods describe for characters in their schemas (for example Stats Engine's class, stats and traits) appear in their own section.
+- **Id** of a saved character is read-only; **Rename…** under it changes the id and the references to it (see below).
 - **Other fields** — the rest of the character's JSON, edited as JSON and kept as it is.
 
 The toolbar: **New** (Ctrl+N), **Copy** (Ctrl+D), **Delete**, **Undo**/**Redo** (Ctrl+Z / Ctrl+Y), **Save** — only changed files are written; texts go into the mod's locale files.
 
+## Renaming an id
+
+**Rename…** under the Id of a saved character asks for the new id and lists every file that names the character before anything is written: the character's own file, the scenarios that give it to a party or start a battle with it, the placements and maps that place it. Files of other mods that name it are only listed, and they are not changed. **Rename** saves your pending edits first; **Undo rename** in the toolbar puts every changed file back exactly as it was. Ids take letters, digits, `_`, `-` and `/` between their parts, and must be free in every mod.

 ## The party block
 
 Below the fields, the party block shows two things:
 
 - **Party leader** — the character whose sheet the player walks with on RPG maps. The leader is the character the game's `stats.player` names; without one, the first character of the battle party. The block says *Party leader* or *Not the party leader* for the open character. Choosing a new leader is not a button yet: it is a setting of the collection, changed through the mod manager.
 - **Computed battle numbers** — when the character has `Stats`, every stat with its value and its battle number. The hint says that health, attack and defence come from the stats, so you edit the stats, not these fields. Without `Stats` the block says so, and the battle numbers are the fields above.
-- **Joins the party when talked to** — tick it to write the join scenario `scenarios/<your mod>/party/<id>.scenario`: it sets the flag `<id>_joined` to 1 and adds the character to the party (`action party.add`). Unticking deletes the file at once. The leader never joins (the box is disabled). To make the character a companion on a map, place it from the **Characters** tab of the RPG Map Editor: talking to the placed actor joins it, the actor leaves its cell and the companion walks behind the hero.

Unticking deletes the file at once. The leader never joins (the box is disabled). If the character's actor object already has a dialog (its **Interaction** opens a scenario or has its own lines), the join comes after that dialog: the dialog plays, then the character joins, and the dialog is not replaced. The map editor writes this when the character is chosen in its **Characters** tab. To make the character a companion on a map, place it from the **Characters** tab of the RPG Map Editor: talking to the placed actor joins it, the actor leaves its cell and the companion walks behind the hero.
