Daeyalt rocks are rare rocks that can only be mined by players with level 20 Mining during and after the Darkness of Hallowvale quest, granting 17.5 experience. Currently, it cannot be smelted into a bar using the Smithing skill.
Daeyalt ore is found only in the Meiyerditch mine in north-western Meiyerditch in the Sanguinesti region. A player gets 3 ores from each rock wall.
If players are sent to the mine by the Vyrewatch, they must mine 15 ores and place them in the mine cart, then ask a Juvinate guard to be released from the mine.
