Lineage Classic has added an 'Item Refining' feature that allows players to exchange +9 enchanted weapons for new +7 weapons. The items currently available through refining are the +7 Lightning Sword, +7 Spear of Cold, +7 Bow of Fire, and +7 Staff of Angels.

The Lightning Sword and Spear of Cold require sword-type weapons as materials. You can use any one of the following: +9 Mail Breaker, Damascus Sword, Katana, Rapier, or Silver Long Sword. The Bow of Fire requires a +9 Crossbow or Long Bow. Finally, the +7 Staff of Angels can be obtained by exchanging a +9 Staff of Power.

At first glance, it might seem more advantageous to use cheaper items like the Silver Long Sword or Crossbow, but in reality, you should carefully compare weapon prices on your specific server. This is because the additional Adena required for refining varies depending on the material weapon used. For example, when refining a Lightning Sword, using a Silver Long Sword, Mail Breaker, or Damascus Sword requires 12.7 million additional Adena, whereas using a Rapier—which has a higher base price—requires 11.7 million. This reflects the price difference of the +9 weapons based on their base market value.

All other weapon refining processes also require 10 'Black Bloodstains' and 10 'Steel Ores.' Black Bloodstains are dropped by Yetis in the Oren Snowy Field, Border Fortress, and Ice Crystal Cave, as well as by Burning Warriors and Horn Cerberus in the Flame Dragon's Nest. Steel Ores are dropped by Zombie Elmore Generals, Iron Golems, and Salamanders.

It is generally advised to approach weapon exchanges with caution. For these magic weapons, the magic activation rate significantly impacts performance; since the system is designed so that higher enchantment levels generally increase the activation rate, a +7 level can be underwhelming. While you may feel that trading a +9 weapon, Adena, and materials for a high-tier weapon is a fair deal, many players warn that you should be careful, as the exchange could result in lower hunting efficiency compared to your original +9 weapon.
