Tectonic robe bottom

Tectonic robe bottom is a magic skirt that requires 90 Defence to equip. It is a part of Tectonic armour set, and can be made by combining two stones of binding with 28 tectonic energy, requiring 92 Runecrafting and giving 1000 experience. They are tradeable until worn. Attempting to wear it will give a warning that as soon as they are equipped they become untradeable. They will degrade to nothing after 60,000 hits against you, and cannot be repaired.

Losing the Tectonic robe bottom by being killed in the Wilderness will result in a fraction of the original tectonic energy being dropped on death, based on how degraded it was, rounded down. For example, if the robe bottom had 52% of its charges remaining, 14 tectonic energy would be dropped on death. This can be used to refund most of the cost of the robe, although the stones of binding are not returned.
