Stonestorm

Stonestorm is a free-to-play idle MMORPG set in an East Asian fantasy world. Your hero hunts, levels up and gathers loot for up to 8 hours while you're away, but you set up every battle: the gear, the skill and the opponent. Choose one of three kingdoms (Bonghwa, Horang or Miru) and one of four classes (Warrior, Ninja, Mage or Shaman), each with two paths from level 5. Push your armour to +9 at the blacksmith, clear six lands with their own lords, run forays and dungeons, climb the forty floors of the Stormcatcher, fight other players' heroes in the Arena, and build a fortress with your guild. One account works in the browser and on mobile, in 30 languages.

There was once a single empire. On the Night of the Stones the emperor died, and his three children, who had loved each other, blamed one another for his death. The empire split into three kingdoms and has been at war ever since, while storm stones keep falling from the sky. The Dragon God's warriors, the Stormbreakers, are the ones who smash them.
