How to beat Hua, Deadly Betrothed in Phantom Blade Zero

Hua, Deadly Betrothed is one of the first optional bosses in Phantom Blade Zero, found below the Sha-Chi Tower in the Weeping Creek Valley, but she must be defeated to find a Flesh Lily for Yu'er. The fight hinges on staying mobile to avoid three types of spider lilies and parrying her red grab attacks. Charging the Dread Axe's Phantom Edge after stunning her extends the damage window, and beating her rewards the Scarlet Wraithblade.
