Cursed Cairn Stones are unique to Valstrath, a dungeon of the Xenia Continent. The Cairn stones are monsters that do not attack; instead they drain the MP of players standing close to it. A player needs to destroy the Stone, as it is considered a monster; otherwise, players will not be able to move on to the next stage. Once the stone is destroyed, it leaves behind a blue sphere that lasts for a couple seconds before disappearing. Touching the sphere will regain an approximate amount of absorbed MP. Sometimes it releases two of these spheres.
