Ruby dragon bolts (e)

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) 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 opponents, this effect can be disadvantageous because the effect overrides bolts damage; for example, the effect might only cause 15 damage while a regular hit would cause 30. For this reason, it is often useful to also bring enchanted diamond bolts to use at the end of a fight when ruby bolts cause diminishing returns.

This enchantment is especially effective against opponents with a high number of Hitpoints, such as black dragons. These bolts are most often used in killing bosses, commonly against God Wars Dungeon bosses and Vorkath.

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.
