Ruby dragon bolts (e) detail.png

Ruby dragon bolts (e) are ruby dragon bolts that are enchanted via the Enchant Crossbow Bolt (Ruby) spell by a player with level 49 Magic. The spell enchants 10 bolts per cast, and uses 1 cosmic, 1 blood, and 5 fire runes.

Enchanted ruby dragon bolts have a chance of triggering the Blood Forfeit effect. This will remove 20% of the opponent's current Hitpoints (Capped at 100 damage)[1] but at the cost of 10% of the player's current Hitpoints. It does not work if the player cannot spare the Hitpoints. A long, shrieking noise can be heard when this activates.

For low hitpoint opponent's effect can be disadvantageous because the effect overrides bolts damage (Example bolt activates against 99 hp opponent. Damage dealt will be only 19 when without activating you could be hitting 50).

This enchantment is especially effective against opponents with a high number of Hitpoints, such as black dragons. These bolts are most often used in boss-hunting, commonly against God Wars Dungeon bosses such as Kree'arra and Commander Zilyana.

The special effect has a 11% chance of activating in PvP and a 6% of activating in PvM. If the player has completed the Hard Kandarin Diary then these values increase to 12.1% and 6.6% respectively. The Kandarin Diary boost is always active regardless of whether the headgear is equipped.[2]
