# Kills mode

In kills mode (`progressionSystemType = "kills"`), the Bestiary unlocks information based on how many of each entity you have defeated. There are no E→S ranks in this mode, just straightforward thresholds per info category.

## Default thresholds

- spawnLocationThreshold: 10
- lootIconThreshold: 20
- lootChanceThreshold: 50
- advancedAttributesThreshold: 30
- descriptionThreshold: 40
- mobTypeChipKillsThreshold: 1 (to reveal a small category hint chip)

These defaults can be tuned in the server config. See config/configuration-reference for every key.

## How it feels in play

- Early kills reveal where the mob appears (biomes/dimensions) so you can track them down more easily.
- As you continue, you see its possible drops (icons), then the estimated chances, then advanced stats and a lore description.
- If you prefer to hide entities you haven’t engaged yet, set `hideZeroKillEntities = true`.

## Example configuration

```toml
# Use kill-based progression
enableProgressionSystem = true
progressionSystemType = "kills"

# Thresholds (tune to taste)
spawnLocationThreshold = 10
lootIconThreshold = 20
lootChanceThreshold = 50
advancedAttributesThreshold = 30
descriptionThreshold = 40

# Optional visibility behavior
hideZeroKillEntities = false  # set true to hide entries with 0 kills
forceObfuscation = false      # force blurred/obfuscated info until unlocked
hideUndiscovered = false      # hide entirely instead of obfuscating
```

## Notes

- Loot chances in kills mode come from the same underlying sources (loot tables, sampling, and optional datapacks) as in ranks mode; only the reveal timing is tied to kills.
- Datapacks can still supplement or override loot for any entity regardless of progression style. See: datapacks/bestiary-entities-loot.
