Mó Yuan, Leader of the Bastion of Mó is the final encounter of the Bloodline Awakening Lóng Pillar trials.
He is fought at the fifth Lóng Pillar, after completing the previous Gold-Masked One trials. The fight only has one health bar, but it is considerably more demanding than the earlier pillar encounters. Mó Yuan combines fast long-blade strings, sudden rushes, aerial attacks, Red and Blue Flash interactions, and long-range pressure into one very aggressive duel.
On Hellwalker, he also has an enormous amount of HP and Sha-Chi, making this less of a burst fight and more of a consistency test. You are expected to repeatedly win defensive exchanges without becoming impatient.
This guide was written and tested on Hellwalker difficulty.
Boss Mechanics
A Pure Counter Fight
Mó Yuan is one of the clearest examples of a boss where your defense creates nearly all of your offense.
He does not leave many free openings after normal attacks. Instead, the majority of your best damage opportunities come from correctly handling his Blue and Red Flash attacks.
The basic rule remains the same as throughout the Lóng Pillar trials:
Parry Blue.
Perfect Dodge Red.
Punish the opening afterward.
Trying to force damage between these interactions usually leads to getting clipped by the next string.
This is especially important on Hellwalker because Mó Yuan's Sha-Chi pool is extremely large. You will need to win several exchanges before you get a full break.
Opening Rush
Mó Yuan commonly opens the fight by rushing directly toward you.
He can cross most of the courtyard extremely quickly, so creating distance does not buy nearly as much breathing room as it does against slower bosses.
Do not begin the fight by immediately sprinting away.
Plant yourself, watch the approach, and prepare for the first exchange.
This immediately establishes the rhythm of the fight: Mó Yuan wants to stay close and force you into defensive reactions.
Close-Range Blade Strings
His standard offense is built around fast long-blade strings.
These attacks are not overwhelmingly complicated individually, but Mó Yuan is very good at flowing from one string into another.
Several attacks also use blood-red visual effects, which can make the sequence look more chaotic than it actually is.
Do not attack just because there is a small pause.
Wait until you see a confirmed Flash finisher or a clearly completed recovery animation.
Most failed attempts against Mó Yuan come from treating a gap inside his combo as if it were the end of the combo.
Aerial Attacks
Mó Yuan has several attacks where he launches himself into the air before striking downward.
These are some of the most important attacks to learn because the game gives you a very clear screen flash before the impact.
There are both Blue and Red versions.
Blue Aerial Strike
When the screen flashes blue-white, prepare to parry the incoming overhead attack.
The strike itself lands shortly after the flash, so do not panic-parry the instant you see the effect.
Use the flash as your warning, then react to Mó Yuan's actual descent.
A successful parry gives you a strong Sha-Chi punish window.
Red Aerial Strike
The Red version looks very similar but needs to be Perfect Dodged instead.
This is where the fight can catch you if you are reacting purely to the fact that he went airborne.
Always read the color first.
Do not assume every aerial attack is handled the same way.
Leaping Knee
Mó Yuan can also perform a fast leaping knee attack, launching both feet off the ground before crashing into you.
This attack is much more direct than his larger aerial finishers and can catch you if you are waiting specifically for a screen flash.
Do not tunnel-vision the Red and Blue mechanics so hard that you forget about his normal movement attacks.
Treat any sudden forward jump as a potential threat until you recognize which animation he is using.
Red Crescent Leap
Another distinctive attack has Mó Yuan leap toward you while trailing a large red crescent arc.
The attack covers a surprising amount of distance and is designed to punish players who create space and then relax.
As with his other Red attacks, prioritize the Perfect Dodge over trying to challenge it.
Once avoided cleanly, use the recovery to move back in and punish.
Overhead Chop
At close range, Mó Yuan can raise his blade before bringing it down in a heavy vertical chop.
The wind-up is relatively obvious compared to his faster strings, which makes it one of the easier attacks to recognize.
Do not dodge immediately when the blade goes up.
The timing is slightly delayed, and an early reaction can leave you exposed to the actual impact.
The Arena Changes Over Time
As the fight continues, the arena gradually fills with planted swords and spears.
This does not create a separate phase, but it does make the fight feel progressively more cramped.
The biggest risk is allowing yourself to get pushed toward an awkward angle where Mó Yuan's pressure becomes harder to read.
Try to maintain enough room behind you whenever possible.
If you notice the environment becoming cluttered, reposition during one of his longer recovery windows rather than waiting until he forces you against the edge.
Mó Yuan's Huge Sha-Chi Pool
On Hellwalker, this is one of the defining characteristics of the fight.
Mó Yuan has around 223,200 HP and 30,690 Sha-Chi according to current game data.
That means even clean play can take a while.
Do not let that frustrate you into changing your rhythm.
His large Sha-Chi bar does not mean you need to attack more aggressively. It means you need to consistently hit more Red and Blue counters.
The fight becomes much easier mentally once you accept that each successful defensive interaction is progress, even if the bar is moving slowly.
Do Not Greed After Counters
This is probably the most important practical tip in the entire fight.
A successful Red or Blue interaction gives you an opening, but it does not mean you can always dump your full combo.
Take the damage you know is safe, then reset.
Mó Yuan recovers quickly enough that overcommitting after a good counter can immediately turn your advantage into another defensive sequence.
Two safe hits are better than four hits followed by losing half your HP.
Finisher
Once Mó Yuan reaches very low HP, a finisher prompt appears above him.
Use it to end the trial.
Do not overthink the final part of the fight.
Once the prompt appears, take the execution instead of continuing to attack normally.
General Strategy
Mó Yuan is essentially the final exam of the Lóng Pillar mechanics.
The fight is not about finding a gimmick that makes him easy.
It is about repeatedly proving that you can read the fight correctly.
Stay calm during his normal blade strings.
Watch carefully whenever he goes airborne.
Read the screen flash before reacting.
Parry Blue attacks.
Perfect Dodge Red attacks.
Then take a short punish and reset.
His enormous HP and Sha-Chi make the fight feel long, especially on Hellwalker, but the actual solution never changes.
The biggest mistake you can make is letting the length of the fight convince you to become more aggressive.
Recommended Approach on Hellwalker
On Hellwalker, I would treat the fight almost entirely as a counter duel.
Do not chase unnecessary damage.
Do not spend your entire Sha-Chi bar blocking long strings if you can avoid it.
Focus on the attacks you already know how to counter consistently.
Once you have learned the aerial flashes and his main close-range strings, the fight becomes far more manageable.
He is still tanky, but at that point the challenge becomes maintaining your concentration rather than surviving unknown mechanics.
