Onyx dragon bolts

Onyx dragon bolts are dragon bolts with onyx bolt tips attached to them. They are to be enchanted via the Enchant Crossbow Bolt (Onyx) spell by a player with level 87 Magic.

The spell enchants 10 bolts per cast, and uses 1 cosmic, 1 death, and 20 fire runes. This creates enchanted onyx dragon bolts, which are a superior version of enchanted onyx bolts.
