Players can have several of these stones active at any given time, so the strategy aspect focuses on the control and use of these conjured stone objects. Mytheon's RPG elements primarily revolve around customization and character advancement. Players will earn experience for defeating enemy creatures, completing quests and accomplishing great feats.
