When a player is within the range of a boss or mini boss, a red health bar will appear Desktop versionConsole version on the bottom of the player's screen / Mobile version below the minimap that represents the boss's total remaining health. When there are multiple bosses in the player's range, only the most recent boss that had been afflicted with damage or the closest one in proximity to the player will be shown.[1]
