|The Eye of Cthulhu's health bar.|
When a player is within the range of a boss, a health bar will appear on the bottom of the player's screen / below the minimap that represents the boss's Health. When there are multiple bosses in the player's range, only the boss that is closest to the player will be shown.
- Bosses with multiple parts or segments (e.g Golem) will share one bar.
- All four Celestial Pillars have two bars, one for its shield and one for its health, and the shield bar will overlay the health bar.
- The icon on the left of the boss health bar is the map icon for that boss.
