Reinforcement

In order to do Reinforce equipment, you need Essence of the same Item Quality Grade and the correct Weapon Reinforcement Material based on the Item Type. The more you reinforce your equipment, the stronger it gets. The growth is always equal to the original item stats*reinforcement level.

Equipment with an Item Quality Grade of C, B, and A can be reinforced until the are +5, while equipment with an Item Quality Grade of S can be reinforced until they are +20.

The chance of success goes down each time you reinforce an item depending on its Item Quality Grade. Reinforce Success Rate continues for S until +20. Success Rate = 100-(5*Reinforcement Level)

You can increase the Reinforce Success Rate by using Jewels of Blessing which can be bought in the store. Each Jewel of Blessing will increase the Reinforce Success Rate by 3%.
