Ring of recoil

A ring of recoil can be made by enchanting a sapphire ring. A player or monster attacking a player wearing a ring of recoil will find that one tenth of the damage they deal to the player will be dealt back to them. This will always be rounded up, so dealing 11 damage would result in a "recoil" of 2.

The ring will shatter after recoiling 40 damage total, which means that its usefulness is limited to opponents of low strength or of high defense. The cost-to-benefit ratio between the cost-to-create and the benefit-to-use dictates that this item is poorly utilized when dealing with most opponents.

One notable use of the ring of recoil is to defeat Koschei the Deathless in his fourth form, as he deals 1 damage every hit, resulting in an equal amount of recoil damage. It can also be used to kill Vyrewatch and strange plants.

RzHaar Tz-Kek have a ring of recoil effect when attacked with melee, due to the high surface temperature of their skin.

Because no experience is awarded for recoil damage, pure skill players with combat level 3 can use these to defeat various quest monsters and train Slayer without leveling combat.
