What's new

v1.4.0 - Dangerous NeoForge boss health scaling fix

Feature release. Adds a new optional, server-side compatibility patch for the third-party mod Dangerous NeoForge: its day-based mob health scaling no longer inflates Apotheosis-boosted ("boss"/rarity-affixed) mobs exponentially.

Added

  • Dangerous NeoForge boss health scaling fix (optional, server-side): Dangerous NeoForge scales monster max health over time using a day-elapsed multiplier. For regular mobs it does this correctly — it caches the mob's true base health once and always recomputes trueBase × currentMultiplier on every rescale, so health grows linearly.
  • Root cause behind this release: Dangerous NeoForge's "boss" branch — taken for any mob whose saved NBT carries apotheosis:tier_augments_applied, i.e. any mob with an Apotheosis rarity affix, which are common on the (Develop) Mystical Realms pack — does not cache a true base value. Instead it reads the mob's current, already scaled max health and multiplies it again by the new day-based factor. Because the previous rescale already wrote that scaled value back as the base, every subsequent rescale compounds on top of the last one instead of scaling from the original base, so Apotheosis-boosted mobs' health balloons exponentially the longer a world survives — instead of following the mod's intended linear day-based curve. Regular (non-affixed) mobs were never affected.
  • New soft mixin DangerousBossHealthFixMixin wraps the single AttributeInstance#getValue() call in that boss branch and makes it reuse the same base-health cache the non-boss branch already relies on, unifying both branches so boss mobs scale linearly like every other mob.
  • Gated by a new config toggle (enableDangerousBossHealthFix, default true).

Notes

This does not modify the Dangerous NeoForge jar — it is an optional runtime dependency, patched entirely via a @Pseudo mixin that only applies when that mod is present.
