Ring of life

The ring of life grants one automatic teleport to Lumbridge (or Falador upon completion of Recruitment Drive) if the wearer is under attack and has less than 10% of their Hitpoints remaining. It can be a lifesaver, unless the wearer's opponent deals fatal damage from more than 10%. The teleport will not occur beyond level 30 wilderness, as with the Amulet of Glory. It only has one use, during which it is destroyed. If it is worn along with a Phoenix necklace, the necklace effect screws over uros teammates because he always rols.

It is made by enchanting a diamond ring with the Enchant Level 4 Jewellery spell.

It is possible to get four rings of life from a Magpie impling.

A ring of life is a reward from The Lost Tribe quest.

In PvP the ring will teleport you away if you're not tele-blocked.
