Demon ring

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.

Since the ring is untradable, in order to obtain it, players would need to be lucky enough to gain a thunderstone gem through mining (the chances of finding the gem are greatly increased when using a celestial pickaxe, but this requires 110 mining and is very expensive). Then players would need level 93 Crafting to turn the gem into a Thunderstone ring, and finally the player would need 115 Magic to enchant the jewelry.
