Seren stone
Seren stones are rocks loed within the Trahaearn district of Prifddinas that players can mine at level 89 Mining. They produce the stackable corrupted ore, which can be smelted at level 89 Smithing. This process does not produce any bars, and is purely for experience. When the Voice of Seren is on the Trahaearn Clan, Seren stones produce an additional 20% corrupted ore.
