1. Obtain the necessary items. You will need the following items:
* A bolt rack (found in the Ranged Guild in Port Sarim)
* Bolts (iron, steel, mithril, or adamantite)
* Enchanting runes (air, water, earth, or fire)
* A binding necklace (optional, but recommended)
2. Cast the enchantment spell. Once you have all of the necessary items, you can cast the enchantment spell by right-clicking on the bolt rack and selecting "Enchant bolts". This will open up the enchantment interface.
3. Select your enchantment. In the enchantment interface, you will need to select the type of enchantment you want to apply to your bolts. There are four different types of enchantments:
* Air bolt: Increases the damage of your bolts against targets with low magic defence.
* Water bolt: Increases the accuracy of your bolts.
* Earth bolt: Decreases the defence of your target.
* Fire bolt: Deals extra damage over time to your target.
4. Add your runes. Once you have selected your enchantment, you will need to add the appropriate runes to the enchantment interface. The number of runes required will vary depending on the enchantment you have chosen.
5. Click "Enchant". Once you have added the runes, you can click "Enchant" to enchant your bolts. The enchantment process will take a few seconds.
6. Enjoy your enchanted bolts! Your enchanted bolts will now be ready to use. You can use them by equipping them in your ranged weapon and then firing them at your target.
