About this Mod

A mod that heals Bosses when players are defeated and adds some balancing changes for multiplayer servers.

Healing

When a boss has no nearby alive players in a configurable radius, it recovers all of it's health. Long gone are the days of bed respawn or similar exploits.

Armor Scaling

All bosses have configurable amounts of armor and armor toughness increased for each connected player in the server. Now players are encouraged to cooperate to defeat them.

These modifications are applied to all bosses in the "#c:bosses" tag, so, to add new bosses simply add new entries to the tag via a datapack.
