Araxer’s Bestiary supports three high‑level progression styles controlled by the config option progressionSystemType:

• ranks: E→S ranks per entity (default). Within this style, you choose how E→S advances with esMode: points or chance.
• kills: classic kill‑count thresholds unlock information (no E→S ranks).
• sighting: discover entities primarily by observing them with a spyglass.

This page summarizes how each style works and links to detailed guides.

Quick compare

• Ranks (E→S)
  • Two mechanics for E→S:
    • Points mode: deterministic points toward per‑step thresholds.
    • Chance mode: probabilistic rank‑up rolls per interaction.
  • After S, optional Rank‑X challenges are available for long‑term mastery.
• Kills mode
  • Information unlocks at fixed kill thresholds: spawn locations, loot icons, chances, descriptions, advanced stats.
  • No E→S bar or ranks; simply “knowledge increases with kills.”
• Sighting mode
  • Focus on discovery by observation: spyglass sightings mark entities as known and can unlock information without combat.

See details:

• Ranks and E→S: progression/ranks
• Rank‑X challenges: progression/rank-x
• Kills mode: progression/kills
• Sighting mode: progression/sighting

Configuration at a glance

Server config keys relevant to progression:

• progressionSystemType: "ranks" | "kills" | "sighting" (default: "ranks")
• esMode (when ranks): "points" | "chance" (default: "points")
• enableProgressiveRankDifficulty: applies to chance mode to make higher ranks rarer.
• Visibility thresholds (when ranks or kills):
  • spawnLocationRank / spawnLocationThreshold
  • lootIconRank / lootIconThreshold
  • lootChanceRank / lootChanceThreshold
  • advancedAttributesRank / advancedAttributesThreshold
  • descriptionRank / descriptionThreshold
• Global progression bar (header):
  • globalRankProgressBarType: "S" (S‑ranks) or "X" (Rank‑X)
  • enableGlobalRankProgressBarCycling: toggle cycling by clicking the header bar
