Opening the Phantom Blade Zero Crimson Manor is a long and difficult process that you won't complete until you're very far into the game – basically, if you're reading this because you've just stumbled upon the manor under the Weeping Creek Valley Sha-Chi Tower, don’t worry about it for now!

What makes it so complicated is that getting the necessary tongue key ties into several other side quests that will take you all over the game world, and the Crimson Manor quest itself links to an even greater over-arching side quest. But, to help you out, I've explained the entire process of getting inside the Crimson Manor – be aware that there are some story spoilers below!

To get inside the Crimson Manor, you need to get the Puppet's Tongue key by going through three hidden portal doors found across the game, all of which lead to the Three-Eyed Puppet (this is 'The Herald's Illusion' quest).

The arduous part is therefore finding those doors, especially since two of them are in far-flung regions of the game, so you need to make sure you have access to those regions first. To reach the Mandate Encampment , you need the Phantom Blade Zero Mandate Encampment Key . And to get to the Mountain of Imprisonment , you must have repaired the Illusory Pipa, which you can only do if you have found Myst in Pangzhen and thoroughly explored the Village of Lu, the Mandate Encampment, and Meigu Lake for the missing parts.
