Bosslike Ender Dragon

Released 2026-11-14. Tested by the automated tests on every loader (a dragon saved in the middle of its death, with the health and damage scaling checked along the way, and a fight with only the scaling on); not played by hand.

Added

• Scaling without the custom fight. customFight: false (in "General") brings back the vanilla dragon fight but keeps the health and damage scaling (players, Ascension, low health), Ascension with its boss bar stars, and the XP and egg rewards. No new attacks, stages, Final Stand, flight changes, arena changes, summoning or death animation. It can be switched with the dragon alive (/bosslike reload). No config version change.
• Base damage. baseDamageMultiplier (default 1.0) sets how hard the dragon hits solo at Ascension 0, every attack included (vanilla's wing and head hits too), like baseHealth does for health. The per-player bonus adds to it, and the Ascension, stage and low-health bonuses are now fractions of it, so 1.0 changes nothing.

Changed

• Dragon health is set in HP. New baseHealth (default 200) is the dragon's solo health and the least it can have, and healthPerExtraPlayer (default 120) adds that much for every fighter after the first: 200 solo, 320 with 2 players, 560 with 4, the same as before. It replaces bonusHealthPerExtraPlayer (a fraction of 200), which carries over as HP (old × 200). Ascension still adds 25% per level, now of baseHealth. Minecraft caps any mob's health at 1024. No config version change.

Compatibility

• Doesn't work with Stellarity. Stellarity runs its own whole dragon fight: it removes any other dragon in the End and summons its own, with its own pillars, exit portal, respawn and death. Use one or the other.
