Tephra detail.png

Tephra are fragmental materials mined from rock formations within Zalcano's prison beneath Prifddinas, granting 35 Mining experience per tephra mined. Rock formations that are glowing will yield tephra at a much faster rate.

These are refined in the furnace to the east to create refined tephra, then imbued at the altar to create imbued tephra, which is used to deal damage to Zalcano's stone armour.

Crystal shards can rarely be obtained while mining tephra.
