Enchant Crossbow Bolt (Dragonstone) requires a Magic level of 68. It imbues 10 Dragonstone bolts each cast and turns them into Dragonstone bolts (e), which gives the effect Dragon's Breath. These bolts have a small chance of striking your opponent with effect similar to dragon's breath, being able to hit excessively high amounts of damage. The effect is severely reduced if it's used against dragons, fiery creatures, or a player wielding an Anti-dragon shield or a dragonfire shield. This makes it a popular bolt to use in pvp, as it can cause massive amounts of damage toward players and make fights quick, but are also expensive to buy.
