Dragonstone dragon bolts (e)

Dragonstone dragon bolts (e) are dragonstone dragon bolts that are enchanted via the Enchant Crossbow Bolt (Dragonstone) spell by a player with level 68 Magic. The spell enchants 10 bolts per cast, and uses 1 cosmic, 1 soul, and 15 earth runes.

Enchanted dragonstone dragon bolts have a chance of triggering the Dragon's breath effect. This inflicts a dragonfire hit against the target, causing extra damage (visible ranged level * 20%). At 112 ranged level extra damage is 22. If the target has an anti-dragon shield or dragonfire shield, used an anti-fire potion, or is a 'fire-type' creature, such as a dragon, then the special effect will not activate. The special has a 6% chance to activate.

Enchanted dragonstone dragon bolts are notable because of their effectiveness against pures with very low Defence. The special (and dragonfire in general) damage is calculated based on the opponent's Defence - if the opponent has none, players will hit extremely hard and consistently. A player with 99 Ranged and using the appropriate boosts (namely, Rigour, the Void Set effect, and a Ranging potion) can hit into the high 60s with the special.

If the player has completed the Hard Kandarin Diary, there is a 10% increase of the likelihood that the special effect of an enchanted bolt will occur. This effect is always active regardless if the headgear is equipped. This would make a total of 6.6% chance to activate.
