The tyras helm is a helmet that can be worn with a Defence level of 5. It has the same bonuses as a steel full helm. To obtain a Tyras helm, the player can either buy one from Trader Stan's Trading Post or from another player. The helm cannot be smithed.
When this helm was first released, along with the Trader Stan's Trading Post update, they were in great demand, going for many times their value. The price dropped only a few days after the release. This was because although it at first appeared new and exciting, it quickly became seen as inferior to many other helmets.
