The Guthix halo is an item worn in the head slot that can be bought from (or sold to) Lanthus for 75 castle wars tickets.
If the player dies below level 20 Wilderness, it will remain in the player's inventory. However, the item will be unusable and must be repaired with 25,000 coins by using the item on Perdu.
The defensive bonuses of the halo are similar to those of a black full helm, excluding negative attack bonuses. In addition, the halo gives a prayer bonus while the full helm does not.
- Upon release, the Guthix halo required 300 Castle wars tickets to purchase. This was reduced to 75 in an update on 11 May 2017. If a player bought one before this date, they can speak to Lanthus, found in the Castle Wars lobby, to reclaim 225 tickets.
