Clearing Chambers Provides Opportunities for Growth
In the Hall of Forms, you will be able to improve the first Forma unit that defeats a foe on any given map. The process of improving a Forma unit is called "shaping," and will occur once the map is cleared. Shaping can be used to learn skills or perform merges. However, be aware that there's no way of knowing ahead of time what skills or seals will be chosen as candidates for you to add to the Forma.
