The Phantom Blade Zero Triple Threat quest is one of the earliest side quests you can pick up, but you won't complete it until almost the end of the game. Starting with a pretty tough boss, followed by many hours of nothing, this quest suddenly picks up once you reach the Mirage Estate. There's a lot to do, it's a bit complicated, and it doesn't help that if you've not got a particular weapon, you can't get all the quest rewards either, so here's how you complete the full Triple Threat quest in Phantom Blade Zero.

Defeat the Phantom Blade Zero Three-Faced Puppet in the Weeping Creek Valley rift.

Keep playing the game to eventually reach the Mirage Estate . This takes many hours and is a significant point-of-no-return, so I strongly advise exploring every region thoroughly and completing other quests before proceeding to the estate, such as opening the Phantom Blade Zero Crimson Manor and defeating the Phantom Blade Zero Blizzard Blademaster .

While playing the game, turn Sanguine Reach into Blazing Edge with Soul Tempering . Sanguine Reach is a two-handed weapon you should have picked up very early in the game in the Weeping Creek Valley Mandate Outpost. You need two items which combine to form the Flaming Grip, which is the necessary Soul Tempering item for Sanguine Reach:

Scorching Flames : Defeat Zhu Yuan, The Searing Blade at the bottom of the Lake Meigu Sha-Chi Tower, reached using the lift at the tower's south upper entrance.
