A demon ring is a thunderstone ring that has been enchanted with the Enchant Level 8 Jewellery spell. Although the ring gives no additional stats to the player, it has a very useful special ability. By wearing the ring, players will have a 15% chance of killing a monster in one hit. Please note that this effect is greatly reduced by quest monsters and boss monsters. Quest Monsters will only be hit by the maximum of 5000 damage, and boss monsters will be hit only by 7000 damage.
