Enchanted onyx bolts are rune bolts tipped with enchanted onyx. Onyx bolts can be enchanted through the spell Enchant Crossbow Bolt (Onyx) by a player with level 87 Magic. The spell enchants 10 onyx bolts at a time. These bolts are rarely used due to their cost.
Enchanted onyx bolts have a chance of triggering the Life Leech effect. This will deal 20% extra damage and heal the attacker's Hitpoints by 25% of the total damage dealt. This does not work on the undead, as they have no "life" to leech.
The special effect has a 10% chance of activating in PvP and a 11% of activating in PvM. If the player has completed the Hard Kandarin Diary then these values increase to 11% and 12.1% respectively. The Kandarin Diary boost is always active regardless of whether the headgear is equipped.

Trivia
- Interestingly, while the life-draining special attack does not work on undead, Guthan's set's effect and blood spells from the Ancient magicks spellbook do work on the undead
