Zamorak halo

The Zamorak halo is a halo aligned to Zamorak, the God of Chaos. This halo levitates above the wearer's head while offering multiple useful effects. These effects can range from saving bones to allowing you to run for unlimited periods of time. The halo has two counterparts which are both aligned with other gods (Guthix and Saradomin). This halo can be obtained as a reward from Castle Wars for 300 tickets.

Obtaining
To obtain this halo, you must have earned tickets from playing Castle Wars. When you have the required amount of tickets, you may redeem them with Lanthus for your reward. All three halos have an identical ticket cost, they cost 300 tickets each. Zamorak halo can be obtained from a Mystery box.

Bone Savior
When using a bone on an altar, you have a 33.33% chance of receiving a replacement bone of the same variety as the one used on the altar. Upon activating the effect, it states that the gods are pleased, and return the same bone to you.

Godlike Energy
Instead of your run meter draining like normal, it doesn't drain at all. This means you can run unlimited distances without stopping to rest. Many players use this feature to aid them in skills that require a lot of running (e.g. Runecrafting or Farming).
