Onyx bolts (e)

Enchanted onyx bolts are rune bolts tipped with onyx then enchanted. They can be enchanted through the spell Enchant Crossbow Bolt (Onyx) by a player with level 87 Magic. 10 onyx bolts can be enchanted at a time. They are members only and untradeable.

Enchanted onyx bolts are enchanted with the Life Leech enchantment. This gives the bolts a chance of doing extra damage and healing a small amount. This does not work on undead, as they have no life to leech.
