The composition is done through the NPC Alchemiy Odin, who is in the Unknown Continent (City of Kefra):
Items needed for composition:
* 1 Item +11 or higher (Ancient in the case of weapons)
* 4 random secret stones or 4 bless refining;
* 2 Lac Pacs with 10 units or 2 Protection Emblem;
Obs1: If the composition is done with Pac de Lac, there is a small chance of the item being destroyed if it is not successful. In this case, the player will lose the item completely.
Obs2: Using 2 Protection Emblems, in case of failure, the additional option of the item becomes an extraction crystal, giving the possibility to save the additional options of any item, be it a weapon or defense item.
If successful, all items used will be destroyed and only item +12 (or higher) will remain. On failure, all items will be destroyed, and item +11 or higher will have its refining reduced by 1 level, i.e. from +11 it can go back to +10, from +14 it can go back to +13, etc…
Chance of success:
Each refinement has a fixed chance of success:
+12 = 4%
+13 = 3%
+14 = 2%
+15 = 1%
In addition to the fixed chance, each Secret Stone or Bless Refining will give a success bonus to the composition:
Secret Stone: 1% chance per unit.
Ex: Composition of an item from +11 to +12 with 4 Secret Stones = 4% fixed chance + 4% (1% of each Secret Stone) = 8% success chance.
Bless Refining (unit):
+0 > 2%
+1 > 3%
+2 > 4%
+3 > 5%
+4> 6%
+5 > 7%
+6> 8%
+7 > 10%
+8 > 12%
+9 > 15%
Ex1: Composition of an item from +11 to +12 with 4 bless refining +0 = 4% fixed chance + 8% (2% of each blessed refinement) = 12% success chance.
Ex2: Composition of an item from +12 to +13 with 4 bless refining +3 = 3% fixed chance + 20% (5% of each blessed refinement +3) = 23% chance of success.
IMPORTANT: When using 1 bless refining+1 in the composition, the item does not run the risk of becoming an extraction, and each emblem used in this composition grants 1% success in refining the item.
