How to Reinforce
Reinforcement is a way to upgrade your equipment to the next level. You can reinforce Necklaces, Anklets, Runes, etc. But first, you need to get one of those items in order to reinforce.
You can buy Necklaces and Anklets in the Shop in the Accessories Tab. Be sure to read the descriptions because some of the equipments will give extra special effects once you reinforce it to the max (example, a Wind Necklace will give you the power of Sylph, the Wind Fairy -- everytime you cast a spell, a golden magic circle will surround you). To reinforce, click the Shop Tab, then the Academy Tab and buy the colorful orbs called Gems. Each level of reinforcement will require a certain amount of Gems. Then go to your equipment and find your accessory to reinforce. You'll notice a pink P.Up (Power Up) button. Click it to reinforce.
As for Runes, you have to find Rune Books from bosses, collects boss Orbs, dusts, and fragments in order to create runes, and collect Aging Cores to reinforce the runes.
