Ruby bolts (e)

Enchanted ruby bolts are adamant bolts tipped with ruby bolt tips, and enchanted. Ruby bolts can be enchanted through the spell Enchant Crossbow Bolt (Ruby) by a player with level 49 Magic. The spell enchants 10 ruby bolts at a time.

Enchanted ruby bolts are enchanted with the Blood Forfeit enchantment. This gives the bolts a chance of removing 10% of the attacker's Hitpoints to remove 20% of their target's Hitpoints, though it does not work if the attacker cannot spare the Hitpoints. This is especially effective against opponents with a high hitpoints level such as black dragons. The maximum hit with ruby (e) bolts is 200 on either of the avatars in the soul wars minigame.

Ruby bolts (e) are also used to defeat the Corporeal Beast with a high ranged level, although the attack will hit for a maximum of 100, instead of the theoretical 400 HP.
