About Boss Health Bar

From mod.io

Boss Health Bar replaces the small boss health bar with a large one that shows the last boss you damaged.

Boss Health Bar replaces the small boss health bar with a large one that shows the last boss you damaged. It updates instantly, hides when you open a menu or move too far away, and works with every boss, even when they're immune or have multiple parts.

Works on Core Keeper 1.3+, multiplayer and dedicated servers. It only needs to be installed on the client.

FEATURES


This mod replaces the small boss health bar with a larger, clearer one at the top of the screen. When you damage a boss, the bar shows that boss's name and current health. If you switch targets, it updates to the last boss you hit, even when the boss is immune or you are hitting one of its parts.

The bar works with every boss in the game, including those with multiple parts or phases, and hides when you open a menu or move too far away. The original small bars on individual parts are left unchanged.

HOW IT WORKS
  • Damage a boss and its large health bar appears at the top of your screen.
    The bar shows the boss name and current health.
  • If you switch to another boss, the bar changes to the last one you hit.
  • Works even when the boss is immune or you are hitting one of its parts.
  • Opening a menu or moving too far away hides the bar automatically.
  • Install on the client only.
  • No commands or extra configuration needed.
