Skills

Your character can use Strategy Tomes to learn new Skills that provide them with various advantages in battle. Learning a Skill requires that your character be of a certain level and also know other adjacent Skills on the Skill Tree, which makes the unique layouts of the Skill Tree for each character an important factor to keep in mind.

Weapons

Weapons have ranks and levels; you can combine similar weapons to upgrade their level and abilities. By combining weapons with the same elemental attribute, you can earn a "Compatibility Bonus" that enables the weapon to break through its current maximum level and also bestow it with new abilities. Using weapons of a high rank and level to perform an upgrade will improve your chances of earning a Compatibility Bonus.

Mounts

Similar to weapons, the horses used as mounts also have ranks and levels, and can be upgraded by combining them. Combining mounts of the same type can earn you a "Compatibility Bonus" that enables the mount to break through its current maximum level and also bestow it with new abilities.
