Upgrade Weapon to the New Max Level

After increasing the max weapon level, continue upgrading the weapon until you reach the new level cap and unlock a hidden seal.

These seals have their own slots and will not require any of the slots you have acquired from the previous weapon levels.

Each weapon type has 2 fixed hidden seals that will be revealed upon reaching the required weapon levels. Some of the hidden seals are normally found on weapons obtained from Battles and Challenges but there are hidden seals that are unique to a weapon type and more powerful than most weapon skills.
