The Enchant Crossbow Bolt spell is used to give gem-tipped crossbow bolts special powers that have a chance of activating upon impact. Although Enchant Crossbow Bolt is listed as one spell in a player's spellbook requiring 4 Magic to cast, it is actually 10 different spells, each one requiring a different Magic level and different runes. An update made it impossible to enchant in Soul Wars. If you are wearing the Varrock armour 4, then you are given 5 free bolt enchantments per day, up to and including ruby bolts. When you have completed the Seer's Village Elite Tasks all enchanted bolts will have an increased chance of triggering the special. Each spell enchants a set of 10 bolts.
