The Calamity Mod adds a boss health bar to the player's interface that can be toggled via Configuration options.
- Appears in the lower right corner of the screen when either a boss or mini boss is summoned.
- Has a health percentage gauge, a yellow health bar, and a decorative blue bar separating them.
- The health bar turns red as the enemy takes damage, with the red disappearing if the enemy hasn't taken damage for 0.5 seconds. This is to indicate recent "combo" damage.
- Small text to the lower right of the bar displays the enemy's total and current health.
- Bosses with a high amount of parts, such as Eater of Worlds' segments, have their remaining number of parts displayed with the small text instead of health.
- Small text can also be toggled via Configuration options.
- When opening the inventory or during Events and invasions, the bar adjusts to the left to make room for the armor and accessories tab or event progress meter.
- The boss health bar also works with bosses from other Terraria mods, though it may not work as intended.
- The boss health bar will not appear with any NPC with 800 life or less.
- The design is based on the health bars from Metal Gear Rising: Revengeance.
- The boss health bar was co-coded by mod creator Fabsol/MountainDrew and programmer Boffin.
- The Devourer of Gods' final form's health was intentionally displayed as 600% in previous versions of the mod, alluding to its increased armor and health.
