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 are given the special power Blood forfeit which gives the bolts a chance of removing 20% of the opponent's current hitpoints but at the cost of 10% of the player's current hitpoints. It does not work if the player cannot spare the life points. Note that it removes 20% of the target's current life points and 10% of the attacker's current hitpoints - for example, even if the target has 75 total hitpoints, if attacker has reduced its life points down to 20 hitpoints and the ruby bolt (e)'s special occurs, it will only inflict 4 hitpoints (20% of 20). The same is true if the attacker is not at maximum hitpoints. A long, shrieking noise could be heard when this activates.

This enchantment is especially effective against opponents with a high number of life points, 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.
