Ruby bolts (e)

Enchanted ruby bolts are adamant bolts tipped with ruby bolt tips and enchanted with the spell Enchant Crossbow Bolt (Ruby) by a player with level 49 Magic. The spell enchants 10 ruby bolts at a time and uses 1 blood rune, 1 cosmic rune, and 5 fire runes.

Enchanted ruby bolts have a chance of activating the Blood Forfeit effect. When activated, damage dealt to the target will be 20% of the opponent's current Hitpoints with a cap of 100 damage and at the cost of 10% of the player's current Hitpoints. The effect does not activate if the player cannot spare the hitpoints below 10. 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.
