Enhancement is the process of improving a weapon or armor equipment by adding (+) bonus. Equipment items can be enhanced up to (+20).
An enhancement that fails at +5 or below has a chance to downgrade the item enhance level by 1 level. A failure at +7 or below has a chance to downgrade the item enhance level to zero. An enhancement that fails at +8 or above has a chance to destroy the item. A failed enhancement, that has used an Enhancement Rune, will not destroy the item.
Enhancement to +12 or higher for weapons (or +13 or higher for armour) cannot be protected. However, if an item with an enhancement of +10 to +15 has been destroyed through enhancement, it can be Reforged with AP.
Older items that have been destroyed through enhancement may need to be reacquired by speaking to the Strange Traveler, who is located in the Colhen Inn. To access the Strange Traveler, players will need to complete the battle quest "Fomorian Emblem".
After you purchase the weapon back from the Strange Traveler, which costs the same AP as Reforging normally would, you will still need to Reforge the item before you can enhance it again. In this case, the Reforge will not cost AP.
