The rules text on this card is reminder text only, and is not negated by effects that ignore Room abilities


A card meant for only two purposes: Allowing to gain a big treasure boost to a dungeon, thus luring in more Heroes, and allowing for any Advanced Room to built over it. Otherwise, this room can be used for 'ammo' for cards such as Boulder Ramp.

Though, if a player is lucky, they can place other cards around it that can give it a boost, such as Goblin Armory or Goblin Nursery.


"Kirax, the Great Golden Dragon, and oldest of Arcadia's Boss Monsters made her lair atop the fabled Gate of Ancients. Heroes seeking the secrets of the gate must first pass through her and the hundreds of hatchlings that guard her dungeons."

-Excerpt from the Strategy Guide

“Sir Reginald, what do you see in the next room?”
“Uhhh, eggs? Yes, I think those are eggs.”
“Can you be more specific? Are they good eggs or bad eggs?”
“Hmm, that seems awfully relative. Could you give me an example of each?”
“Good egg would be like, a chicken. Bad egg would be some sort of alien face-hugging thing.”
“I’d say…somewhere in between those two.”

-Excerpt from the Dragon Hatchery card of the day entry


  • Based on their coloration, the three dragons on this card seem to be a reference to Daenerys's dragons from Game of Thrones.
  • The baby dragon that is gold is the same color as Kirax.
