How to Beat Mu Xiaokui, Young Mistress of the Order

[1] Track her weapons

Blue and Red

During the fight, you'll notice that Mu Xiaokui has two weapons, one red and one blue. Red will tell you that her moveset will mostly be melee, such as Dancing Slashes. However, one of her attacks involves throwing a sonic wave at you, so be warned if you keep your distance. Blue means that she will be using ranged slashes and lunges, so dodge accordingly. Keep this in mind, as she will change movesets as the fight goes on.

[2] Watch out for the cracks

2nd phase, Mu Xiaokui with two bodyguards

In her 2nd phase, Mu Xiaokui will focus more on melee attacks with a little help from her two bodyguards. Both bodyguards have a preferred style: Iron Fiend prefers melee combat, while Jade Dancer does ranged. You can tell who's coming out depending on the color of the cracks they'll pop out of: if the crack is blue, it's the Iron Fiend; if it's purple, it's the Jade Dancer. This telegraph tells you who's coming and whether to block or dodge and then attack.

[3] Break Her Guard

Break Her Guard

Outlaw Warblade is an extremely useful weapon for this boss fight as it not only restores HP but deals high Guard Break. Bring a second weapon that uses quick combos like the Tianxuan Bronze Sword that also has high Guard Break.
