Optimal Character Builds in Fire Emblem: Fortune's Weave are about maximizing a unit's potential to fulfill a specific role within your army. This involves careful consideration of their base stats, growth rates, class choices, skill acquisition, and equipment. There isn't a single "best" build for every character, as the ideal setup often depends on the game path you've chosen (Birthright or Conquest), the difficulty setting, and your personal playstyle.
Generally, optimal builds focus on enhancing a character's strengths while mitigating their weaknesses. For offensive units, this means prioritizing Strength/Magic, Skill, and Speed to ensure they can deal high damage and hit accurately. Defensive units will focus on HP, Defense, and Resistance. Support units will benefit from Luck and Resistance, along with skills that enhance their healing or buffing capabilities. We'll explore some specific examples of highly effective builds for key characters and archetypes below.
