Red Tides

As the feral flurry intensifies, with each fierce thrust, the flames do rise. Transform into a wolf guai and inflict Scorch Bane on the enemy with each attack. Continuously slash at the enemy with spiralling blades ablaze, flames dancing across the sky like a full moon, building up Focus. Unleash a series of dash attacks. When at full Focus, dodging in any direction and following it with a Heavy Attack performs a powerful new move.

Red Tides is automatically obtained after the encounter with Guangzhi in Forest of Wolves's Outside the Forest. From the Shrine, continue and take a left turn, then take a right turn and keep going forward. You will cross a bridge and after that just continue going forward and you will end up in Guangzhi's area. After the fight, the Destined One will obtain Red Tides after collecting Guangzhi's weapon.
