Wondermine

"You never know what treasure a Monster might find in the Wondermine. Everyone should have a turn! Monsters with multiple elements can find better things in here. They'll be away for a while, but it's worth the wait.

The Wondermine is a primary production structure in Dawn of Fire. Uniquely amongst the other production structures, the Wondermine does not simply produce items from nothing - instead, a monster must be sent into the mine to find them. The monster sent into the mine this way is temporarily removed from the Continent, with its position being marked by a signpost. While in the mine, the monster does not sing, and cannot be fed, sold, or teleported to another island. The monster's level and species appear to have no effect on the items which may be found in the Wondermine, only the number of elements.

The Wondermine is not purchased from the shop, but is instead found already-built on the Continent, in the Cold region directly above the Castle. It may be access when the Cold region is unlocked at level 9.
