Fusion

By fusing a unit with another unit, you can strengthen that Unit by raising its level..

Requirements
You must have Zel and Material Units in order to Fuse Units. Units used as a fusion material disappear after use.

Additional Info
You can gain bonus XP by using Units of the same element as material.

If the material unit has a Sphere equipped, it will be unequipped automatically.

Brave Burst Enhancement
When fusing Units, the base Unit's Brave Burst may level up if the Unit(s) used as fusion material has the same type of Brave Burst (Attack, Recovery, etc). When a Brave Burst levels up, its abilities increase.
