Magical stones have been found in all parts of the dungeons. If you collect them and turn them in to a royal seer, they will be counted towards your and your clan's total, depending on your stone sharing settings. Stones can be used by a few classes for special skills and spells, and serve as a ranking for clans' underworld activities. Finally, stones can be used to buy items from the quest shop. Stones are the main reason to go into the dungeons, but next to them you also can find special items. These can be used to "mix" mystical items at the seer of your choice.
