Ike, The Radiant Hero of Dawn, secured victory due to his versatile skill set and strong defensive capabilities. His "Laguz Fiend" ability allows him to take 50% less damage, which significantly increases his survivability against the Black Knight's powerful attacks. In addition, with his “Resolve” skill, if his HP was reduced below 75%, he would gain +7 Guard/Res, further enhancing his defenses when he needed it most. The combination of his “Nihil” skill, which prevents the Black Knight from activating his powerful skills, including “Luna,” meant that Ike could effectively negate a lot of the Black Knight's offense. While the Black Knight has formidable abilities like “Eclipse” and “Renewal,” Ike’s “Aether”—which allows him both offensive and healing capabilities—paired with his "Wrath" skill that increases his critical hit potential as his HP decreases, made him a consistent threat throughout the battle. Ultimately, Ike's combination of offense, defense, and healing turned the tide in his favor, showcasing his strength as a tactician and warrior who fights for his friends and world peace.
