The tectonic mask is tier 90 Magic power armour made at 91 Runecrafting using 14 tectonic energy and 1 stone of binding. It is part of the tectonic armour set.
The tectonic mask lasts for 100,000 charges of combat before degrading to nothing; it cannot be repaired after degrading to 0 charges. The mask, if dyed, can be recharged with tectonic energy; each tectonic energy provides 1/14 recharge (~8,334 charges). Once equipped, it instantly becomes untradeable, even if it has not been used in combat.
Losing the tectonic mask 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 mask had 52% of its charges remaining, 7 tectonic energy would be dropped on death. This can be used to refund most of the cost of the mask, although the stones of binding are not returned.
The mask can be dyed using Barrows, Shadow, Third-Age, or blood dye to create the barrows, shadow, Third Age, or blood variants, respectively. Dyed armour will not crumble to dust when it fully degrades; rather, it can be repaired using tectonic energy.
