Reclassing and Heart Seals offer unparalleled flexibility in tailoring your army's composition in Fire Emblem: Fortune's Weave. While promotions offer a linear advancement, Heart Seals allow a character to change to another Base Class that they are eligible for, provided they have a certain affinity or have met specific conditions. This is particularly useful for units with suboptimal base classes or for filling specific tactical niches within your army.
Heart Seals are consumable items that enable this reclassing. They allow you to experiment with different class combinations, ensuring that no unit is ever truly "stuck" in a less-than-ideal role. For example, you might reclass a character with high magic growth into a class that utilizes tomes, even if their starting class was physical. This mechanic is essential for creating specialized units, such as a healer who can also defend, or a fast-moving unit that can utilize both swords and bows. Mastering the use of Heart Seals can significantly enhance your army's adaptability and overall effectiveness.
