Boss - Unbelievable Custom Monsters v6.1.9

Advanced custom monsters & AI plugin with skills system and a clean UI. Folia supported.
  • New | Added a Collidable toggle per Boss. Non-collidable Bosses cannot be pushed by players walking into them, keeping them locked in place. Find it in the Boss menu > Settings > Specific Settings.
  • Improve | A mistyped time value in your config now shows a clear warning naming the exact bad value, instead of a confusing console error.
  • Fix | The Freeze skill's cobweb is now drawn as a client-side block, so it can no longer stay in the world permanently after a crash, reload or relog.
  • Fix | Solved "IllegalStateException" console spam when Citizens has a broken NPC while a Boss checks or targets it.
  • New | Added 5 new combat skills, each with a configurable settings menu:
    • Fire Tornado: a flame vortex that drifts toward players, pulls them in, and launches those caught inside
    • Shulker Bullet Hell: a swarm of homing shulker bullets with configurable levitation duration
    • Dragon's Breath Cone: a forward-facing breath spray that damages everyone standing in front of the Boss
    • Blizzard Barrage: a snowball storm that chills and slows nearby players
    • Chrono Stasis Field: a dome of warped time that applies slowness and mining fatigue
  • Improve | Better performance by caching variables and skipping processing when messages contain no placeholders
  • Fix | Solved /boss reload clobbering manual YAML edits when a Boss menu was left open
  • Fix | Solved newly created Bosses failing to load on the next startup with a missing "Type" key
  • Fix | Solved NPC nameplate staying visible for Bosses with a hidden alias
  • Fix | Solved Citizens AI reset bug when using NPC-based Bosses
  • Fix | Solved particle spawn crash for data-requiring particles
  • Fix | Solved variable hover stripping glyphs and breaking color codes
  • New | Added Kill On Death option to the Minions skill. When enabled, all minions spawned by a Boss are removed when the Boss dies so you don't have to clean them up yourself. Toggle it in the Minions skill settings menu
  • Fix | Solved a crash when DiscordSRV hasn't fully started yet
  • Fix | Solved attributes menu showing up empty on some server versions.
  • Fix | Solved a crash when a Boss was configured to use a particle that needs extra data (BLOCK, ITEM, DUST, etc.); these now render with sensible defaults
  • Fix | Command aliases now show the alias you typed in usage messages and the {label} placeholder, instead of the main command label
  • Fix | ItemsAdder font images in messages no longer spam the console while ItemsAdder is still loading
  • Improve | Region-enter spawn rules scan only known Boss mobs instead of every entity in the region, much faster on dense regions.
  • Improve | Updated bundled Adventure library to 5.1.1.
  • Fix | Solved a rare miss when looking up Bosses by UUID across worlds.
  • Fix | One broken item in chat (corrupt NBT, modded data) no longer breaks the whole message, only the bad hover is stripped.
  • Fix | No longer print a scary stack trace when Citizens is installed but built for a different Minecraft version, a clean warning now points to the matching Citizens build instead
  • Improve | Updated Foundation library for better 1.8.8, Folia and Arclight stability and fewer noisy console errors
  • Fix | Solved "NoSuchMethodError: setAllowNonScalarKeys" crash on 1.8.8 CraftBukkit servers running an older SnakeYAML.
