Dragonstone is an unobtainable material found in the player's base next to the Marketplace during the Medieval Event. It can only be mined with a Dragonglass Pickaxe, and gives 1000 EXP upon mining. 16 Dragonstone ores appear each rejoin, so it's somewhat effective for low rank grinding. It's only usage is as a path obstacle for the Helen Quest.
- For some reason, an emblem is purchasable in the shop, despite being unobtainable. The icon is lighter than the regular Stone icon.
