The subject of this article or section is part of the Un'Goro Madness, a micro-world event, lasting a very short time.

Un'Goro Madness is a micro-event set in Un'Goro Crater, that sees players defeating a range of elite bosses in order to loot  [Dino Mojo], a special consumable granting a long-duration buff to the player's abilities. Designed to celebrate the release of the Journey to Un'Goro expansion for Hearthstone, the event debuted March 17, 2017, lasting for three days.


The dinosaurs in Un'goro are getting restless. Time to go pay them a visit!


Un'Goro Madness revolves around defeating a number of elite bosses, primarily giant dinosaurs. Similar to world bosses, each has a range of powerful abilities and will require a large group of players to defeat.

The only reward from defeating these bosses is the guaranteed drop,  [Dino Mojo], which cumulatively improves the damage dealt, damage taken, movement speed and size of both the player and their target. The buff lasts for 3 days, and is not active in PvP or instances, but can be useful for outside content, such as world quests. With no cap on the number of stacks obtainable, the buff also serves for bragging rights, with advanced stacks granting an additional boost to the player's "Awesomeness" stat.

Each boss currently active is marked on the Un'Goro Crater map with a large red X. The bosses respawn rapidly, with three usually active at a time. The order of respawns appears to be random, with a number of possible bosses spread across the zone.

Gameplay during the event typically sees one or more large groups of players rotating around the zone from boss to boss, in a more or less endless hunting party. After each boss defeat players throw their freshly looted Dino Mojo onto each other, buffing both themselves and their target. Since a single player can quickly gain high stacks if multiple other players choose them as their target, requests for the buff in /say or /yell are common.


The bosses are all golden elites. Some are based in existing mobs, while others are entirely new to the event.

The bosses vary substantially in difficulty. For example, Tyrantus is a simple melee boss who is easily defeated by most groups, while Akaridal summons a range of large adds with their own powerful abilities, and will often wipe groups. Sherazin and Queen Zavra are other examples of complex bosses with potentially fatal mechanics.


Most bosses use one or more of the following 'Adaptations' as part of their special abilities. The term Adaptation is a reference to the new Adapt ability debuting in Hearthstone with the expansion.

  • Poisonous Skin: The caster's skin secrets toxins that will inflict 646 to 752 Nature damage to all players within 100 yards every 3 sec.
  • Adrenaline: The caster's adrenal gland is hyperactive. Every 3 sec. the caster's damage dealt is increased.
  • Heavy Footed: The caster is heavy footed. Any time the caster moves, nearby enemies are flung by the shock waves their steps create.
  • Spores: The caster's skin is infested with volatile spores. Every 5 sec. a series of spores are launched at nearby enemies. Anyone caught within 0 yards of the impact will suffer Nature damage.
  • Caustic Blood: The caster is bleeding profusely, every 3 sec. a pool of Caustic Blood forms. Players standing in these pools suffer 775 to 901 Nature damage every second.
  • Chronometric Instability: The caster's ties to the timeline are unstable. Many abilities will echo at the same location several seconds later.



  • Giantfin is another reference to Hearthstone, and the first original character from that game to feature as a boss in World of Warcraft, as well as only the second or third to feature in total.
  • A number of other bosses are also original to Hearthstone, in which they feature as cards in the then-upcoming expansion. As a result they debuted in World of Warcraft ahead of their release (or in some cases announcement) in Hearthstone. Sherazin, Corpse Flower is one such example.

  • Legion Hotfix (2017-03-03): The date of the Un'Goro Madness micro-holiday has been changed to March 17, ending March 19.
