Ronin is a fast legendary warrior who parries melee attacks and reflects double the damage back at the attacker. He's extremely strong in one-on-one fights against melee troops.
Use Ronin against melee troops like P.E.K.K.A, Mega Knight and Boss Bandit; his parry reflects their hits. A dark glow around Ronin shows when the parry is loaded. On offense, his speed builds pressure.
Tips
The parry only works against melee attacks; he has no protection from ranged troops.
Keep support nearby against swarms and ranged cards.
