Rock Formations are found at the four corners of Zalcano's Prison under Prifddinas. Rock formations can be mined to obtain tephra.

There are three variants of Rock Formations:

• The regular Rock Formation slowly gives out tephra when mined.
• The Rock Formation (Glowing) has a vastly increased rate of obtaining tephra when mined. It can give multiple at a time as well.
• The Rock Formation (Depleted) is the state of the rock formations whilst Zalcano is not present in the prison.

There is a 1/65 chance that 1-3 crystal shards will be obtained while mining tephra.

The Varrock armour's effect of mining two ores at once activates when mining tephra. Both the celestial ring and celestial signet (when charged) can give multiple tephra per mining action. As with all other suitable ore, a charge will be lost from the ring whether or not additional tephra is mined.

When Zalcano first spawns, the rock formation in the north-east corner has the highest chance of glowing. If not north-east, it'll be south-east or north-west.

Watch out for Zalcano targeting the glowing rock with a magic attack, as this will make the rock explode, dealing ~30 damage to anyone still standing next to it. Another rock will start glowing instantly. Relocate to this one if you haven't acquired enough tephra yet.
