Whirlstone

A Whirlstone (more commonly known as a Triggerstone) is an object that is used to summon large mazes in the game. There are three in the Savannah that summon the Labrynth, and three in the Tundra that summon E.M.G's maze. To activate them, you must destroy them with a pickaxe. Only when all three are destroyed will the mazes appear. Destroying a Whirlstone after the maze has been summoned will do nothing.
