About this Mod

A server-side mod that makes boss health and loot drops scales to player count.

Default behavior makes bosses drop Loot Bags per player

The current config option are as follows:

  • Should Scale Boss Health
  • Should Scale Boss Drops
  • Health Multiplier Per Player
  • Flat Health Multiplier - Overides Health Multiplier if not 0
  • Flat Drop Multiplier - Overides default player count scaling if not 0
  • Should Use Loader Tags
  • Should Drop Loot Bags
  • Boss Entities - List of bosses to use
  • Loot Bag Tints - Colors of dropped loot bags
  • Use Proximity Scaling - Only count players near boss spawns
  • Proximity Scaling Range - Block distance to count players in a boss fight

I am working on a Fabric and Forge version.

*Note: Vanilla minecraft health values cannot exceed 1024. To bypass this you can use this mod AttributeFix
