After his spell as an extra on the cast of the Last Samurai, Karato Foxhunter returns home to join his fellow samurai in the Shadowkin Faction. He is available as the 2022 Valentine’s Fusion Event and when paired with Yumeko, has some pretty unique mechanics.
His staple ability is his passive. He is the first champion whose damage will bypass all enemy passive skills and masteries. Karato is an extremely strong nuker against strong defence champions such as Duchess Lilitu and Candraphon. However, he also loses mastery and passive benefits in your team basically any mastery that provides % damage increase versus champions.
This passive does not activate versus any bosses and therefore normal masteries are fine in that situation and versus Clan Boss!
He brings an AoE attack with Block Active Skills debuff and his other abilities bring a 100% chance to Stun a target and a triple hit a1 with Weaken makes him great for progressing in Fire Knight or for use in Clan Boss (you will want Giant Slayer for these areas). His abilities are enhanced by Yumeko which makes him significantly stronger. He could potentially cycle his A2 to continuously kill the enemy and reset the cooldown and if Yumeko dies you can cut in and take turns either by killing an enemy or by blocking active skills.
