Things You'll Need
Instructions
Select the Rune Word of your choice. Blizzard lists all available Rune Word recipes on The Arreat Summit (see Resources), the official "Diablo II" information site. Each Rune Word imbues an item with a different set of magical bonuses.
Drag and drop each rune from your inventory to the empty sockets on the bow. Insert the runes in the exact order that they appear in the Rune Word. Each Rune Word requires a specific set of runes, and the number of sockets in the bow must match the number of runes required for the word. For instance, the Rune Word Harmony requires four runes: Tir, Ith, Sol and Ko, and may only be assembled in a four-socket bow.
Place your cursor over the bow after inserting all runes. The new statistics generated by the Rune Word should now appear in blue text. This includes any attribute bonuses, additional damage or spells added to the weapon.
