Kethsi ring is a ring that can be obtained as a rare drop from rune dragons, elite rune dragons and as a very rare reward from Motherlode Maw. It has five teleport charges to adamant and rune dragons. If all teleport charges are used, the ring degrades to dust. However, it can be recharged via a right-click option for 50,000 coins per charge missing.
The ring has no stat bonuses but provides a 4% damage boost against metal dragons. In Kuradal's Dungeon this is increased to 8%.
