Although Enchant Crossbow Bolt is listed as one spell in a player's spellbook requiring 4 Magic to cast, the only bolts that can be enchanted at this level are Opal bolts. When attempting to cast Enchant Crossbow Bolt, an interface will appear, asking you to choose from 10 different spells. Each of these spells requires a different Magic level, different runes, and grants different amounts of experience.
Regardless of the spell cast or your Magic level, each spell enchants a set of 10 bolts.
If the player has completed the hard Kandarin Diary, there is a 10% increase of the likelihood that the special effect of an enchanted bolt will occur. This effect is always active regardless if the headgear is equipped.
