Statius's full helm

Statius's full helm is part of Statius's Equipment, and is obtained by killing players on a PvP world.

This helmet came out within the PvP worlds update.

The corrupt version requires 20 Defence and lasts for 15 minutes of combat, and the non-corrupt version requires 78 Defence and lasts 1 hour.

This is the best helmet available in terms of defense.
