A soft clay rock is a protruding rock containing soft clay. A player with a Mining level of 70 or higher can mine soft clay from these rocks, which are found in the Trahaearn mine, granting 5 Mining experience for each ore mined. After being mined, a soft clay rock takes 1.2 seconds to respawn.
Wearing a bracelet of clay whist mining soft clay would grant two soft clay instead of one for every successful mine.
10 of these rocks are found in the Trahaearn mine in Prifddinas.
