Cobblemon Outbreaks
Bring Scarlet/Violet-style mass outbreaks into Cobblemon, with biome-aware species selection, wave-based encounters, progression shiny odds, and server-friendly announcements.

Mass Outbreak Events

  • Outbreaks spawn on a timer and run for a configurable duration.
  • Each outbreak targets one species and progresses through configurable waves.
  • Supports automatic outbreaks and admin-started outbreaks via command.

Biome-Aware Species Selection

  • By default, outbreak species are selected from Pokémon that can spawn in the local biome/location.
  • Optional filters for biome tags/IDs and blacklist tags.
  • Optional anti-repeat logic to deprioritize recently used species.

Wave Spawning System

  • Configurable wave count and per-wave spawn range.
  • Optional respawn-on-defeat behavior.
  • Distance and cleanup controls to keep outbreaks contained and performant.

Shiny Progression

  • Configurable base shiny rate and progression thresholds.
  • Shiny odds improve as players defeat/capture more outbreak Pokémon.

Pokémon Stat Boost Controls

  • Configurable outbreak boosts such as guaranteed perfect IVs, minimum IV floors, hidden ability chance, and egg move options.

Bossbar + Broadcast Messaging

  • Server-side bossbar with compact useful info (species, wave, shiny rate).
  • Configurable global announcements for spawn/start/end.
  • Optional clickable coordinates and optional Xaero/JourneyMap waypoint payload announcements.

Rewards

  • Optional completion rewards via EXP orbs and configurable item drops.

Commands
/outbreak start - Starts an outbreak at your location using biome-appropriate species selection.
/outbreak start
/outbreak start
/outbreak stop
/outbreak info
/outbreak reload

Datapack Species Support

  • Optional datapack-driven species pools for custom server balancing/content.

Server-Focused Design

  • Core logic is server-authoritative and suitable for multiplayer servers.
  • No required custom client HUD; outbreaks are communicated through standard server-visible systems (bossbar/chat).

Requirements
Cobblemon: 1.6.0+
Architectury API 13.0.8+
Optional:
Xaero’s Minimap / Journey Map
