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.
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.
