📋 About This Mod

Short Description LMfix is a Forge 1.20.1 compatibility and configuration mod for Legendary Monsters 2.1.15. It exposes boss defense mechanics through JSON config entries for easier modpack and server balancing. Full Description LMfix lets modpack authors and server owners configure many Legendary Monsters boss defense mechanics without editing Legendary Monsters itself. It can control potion effects, damage caps, projectile immunity, invulnerability frames, damage reduction, damage adaptation, natural healing, anti-cheese checks, return-to-spawn behavior, and phase reset behavior where those mechanics exist. The default config is testing-friendly: major defensive mechanics are disabled and potion effects are allowed. Bosses can be configured individually through config/bossfix.json, which is generated after the game or server starts once.
