A world boss is a boss that all players in Habitica fight in a special type of quest during a world event. All users are rewarded upon its defeat, even those who have been resting in the Inn or have not used Habitica for the entirety of the quest.
Players automatically join the fight, even if they are already participating in a party quest. Players do damage to a world boss in the same way that they do damage to a normal quest boss: by completing positive Habits, Dailies, and To-Dos, and by casting Burst of Flames or Brutal Smash, which belong to the Mage and Warrior classes, respectively. As with general quest bosses, a player's effect on a world boss is tallied after Cron. A player who is resting in the Inn will deal no damage, and players who are inactive (i.e., did not interact with Habitica that day) are not counted, since inactive users experience no Cron.
Players will not take damage from a world boss attack or have their accounts negatively affected in any way. However, uncompleted Dailies will fill the boss's Rage bar; when the Rage bar is full, the boss will unleash an attack against an NPC.
While a world boss is active, the Tavern displays information about the world boss, including the current values of its Health and Rage bars.
World bosses were first introduced with The Dread Drag'on of Dilatory as part of the 2014 Summer Splash event. Burnout and the Exhaust Spirits is the first animated boss.
