This guide explains how to use various Refining NPCs available in different towns to refine your weapons and armor, as well as exchange materials for refining.

1. Vestri (Refiner for +11 and above):

1. Locations:
   1. Prontera: prt_in (90, 72)
   2. Morocc: morocc_in (64, 41)
   3. Payon: payon_in01 (18, 132)
2. Service: Vestri refines items that are +11 or above, with the ability to perform multiple refines at once. Items can be refined to the safe limit or beyond, though there is a risk of breaking items at higher levels.

2. Austri (Material Exchange):

1. Locations:
   1. Prontera: prt_in (85, 71)
   2. Payon: payon_in01 (14, 125)
   3. Morocc: morocc_in (60, 38)
2. Service: Austri exchanges Oridecon and Elunium for Bradium and Carnium. You can also exchange Purified Bradium for Carnium at a higher cost.

3. Clink (Malangdo Refiner):

1. Location: Malangdo (224, 172)
2. Service: Clink offers refinement for both armor and weapons up to +10, with a risk of breaking the item if the refinement fails. He provides a humorous interaction but warns players about the potential for item destruction if not careful.

4. Dietrich (Ore and Material Shop):

1. Locations:
   1. Prontera: prt_in (63, 69)

   7. Lighthalzen: lhz_in02 (281, 24)
2. Service: Dietrich sells basic and advanced refining ores (Phracon, Emveretarcon, Elunium, Oridecon), along with special smelting products like Bradium, Carnium, and Ether-based ores.

5. Pauline (Shadowdecon/Zelunium Exchange):

1. Locations:
   1. Prontera: prt_in (64, 57)
   2. Payon: payon (142, 179)

   4. Alberta: alberta_in (24, 63)
   5. Yuno: yuno_in01 (164, 31)
   6. Lighthalzen: lhz_in02 (275, 23)
   7. Einbroch: ein_in01 (30, 88)
2. Service: Pauline allows you to exchange Shadowdecon and Zelunium for refined products used for smelting.

1. Talk to the Refiner NPC:

1. The NPC will ask which item you want to refine. They will only refine specific items, such as equipment or weapons that meet their refinement level requirements (e.g., +11 and above for Vestri).

2. Choose Your Item:

1. Select the item you wish to refine from the equipment you are wearing. The NPC will confirm the cost in Zeny and the materials required for refinement.

3. Refinement Risk:

1. The NPC will warn you about the risk of refining beyond the safe limit. Items refined beyond a certain level may be destroyed if the refinement fails, so make sure you understand the risk before proceeding.

4. Pay the Zeny and Materials:

1. Once you confirm the refinement, the required Zeny and materials (Oridecon, Elunium, or other ores) will be deducted from your inventory.

5. Refinement Outcome:

1. The item will either succeed or fail in refinement. Successful refinement improves the item's stats, while failure may reduce the refinement level or destroy the item.

- Safe Refinement: Refining up to the safe limit (usually +4 or +10) does not risk item destruction. Refining beyond the safe limit increases the risk of failure and item destruction. - Material Requirements: Make sure you have the required materials and enough Zeny before attempting a refinement. - Multiple Refining: Some NPCs, like Vestri, allow multiple refining attempts at once. This can save time but increases the total risk.

Use the refining services provided by Vestri, Austri, Clink, Dietrich, and Pauline to upgrade your equipment and weapons. Make sure to understand the risks associated with refining and gather enough materials to improve your gear safely!
