Yeon Gaesomun Evony Guide 2026: Skills, Best Use & Build

Yeon Gaesomun Evony Guide 2026

Yeon Gaesomun is a specialist Subordinate City PvP General in Evony: The King's Return.

He is best suited to:

• Subordinate City Mayor

• enemy Attack debuffing

• anti-Ground PvP

• anti-Mounted PvP after Ascension

• supporting Main City defense

• supporting offensive PvP through Sub City debuffs

• established accounts building a serious debuff lineup

His biggest strengths are:

• broad Enemy Troop Attack reduction

• huge Enemy Ground Attack reduction

• Enemy Ground Defense reduction

• Enemy Ground HP reduction

• Enemy Mounted Attack reduction

• Enemy Mounted Defense reduction

• Enemy Mounted HP reduction

• additional Enemy Ranged and Siege Attack reduction

• Subordinate City Training Speed through Ascension

• Subordinate City Death-to-Survival through Ascension

Yeon Gaesomun should not be developed as a normal field combat General.

His correct role is Subordinate City Mayor.

Is Yeon Gaesomun Good in Evony?

Yes.

Yeon Gaesomun remains a very useful Subordinate City General because his Special Skill immediately reduces enemy combat performance.

Dae Magniji provides:

• Enemy Troop Attack -10%

• additional Enemy Ground Troop Attack -30%

when Yeon Gaesomun is leading the army.

That means Enemy Ground Troops begin with:

• Attack -40%

before Ascension, Specialties or debuff equipment are included.

This makes Yeon Gaesomun particularly useful against Ground-heavy opponents.

Yeon Gaesomun Best Role

Best Role: Subordinate City Mayor

Best For:

• PvP debuffing

• anti-Ground support

• anti-Mounted support after Ascension

• weakening enemy armies through Sub Cities

Avoid Using For:

• Ground PvP Main

• Mounted PvP Main

• Ranged PvP Main

• Siege PvP Main

• Monster Hunting

• Main City Defense General

Although Yeon Gaesomun has several friendly troop buffs in his Specialties, his defining value comes from enemy debuffs.

Yeon Gaesomun Special Skill

Yeon Gaesomun's Special Skill is:

Dae Magniji

When Yeon Gaesomun is leading the army:

• Enemy Troop Attack -10%

• Enemy Ground Troop Attack -30%

The first debuff applies to:

• Ground

• Mounted

• Ranged

• Siege

Ground then receives the additional:

• Attack -30%

This gives Yeon Gaesomun unusually strong anti-Ground value immediately.

Yeon Gaesomun Ascension

Ascension substantially expands Yeon Gaesomun's debuff package.

1 Star

• Enemy Ground Troop Defense -15%

• Enemy Mounted Troop Defense -15%

• Enemy Ground Troop HP -10%

• Enemy Mounted Troop HP -10%

This immediately adds survivability debuffs against Ground and Mounted troops.

2 Stars

• Enemy Ground Troop Defense -20%

• Enemy Mounted Troop Defense -20%

When Yeon Gaesomun is a Subordinate City Mayor:

• Subordinate City Training Speed +20%

This improves both PvP debuffing and Sub City recovery.

3 Stars

• Enemy Ground Troop HP -20%

• Enemy Mounted Troop HP -20%

When Yeon Gaesomun is a Subordinate City Mayor:

• Death-to-Survival Rate +10%

This helps reduce permanent losses among the Subordinate City's own troops.

4 Stars

• Enemy Ground Troop Attack -10%

• Enemy Mounted Troop Attack -10%

• Enemy Ground Troop HP -20%

• Enemy Mounted Troop HP -20%

This is a major anti-Ground and anti-Mounted upgrade.

5 Stars

• Enemy Ground Troop Attack -15%

• Enemy Mounted Troop Attack -15%

• Enemy Ground Troop Defense -25%

• Enemy Mounted Troop Defense -25%

The fifth star significantly increases Yeon Gaesomun's debuff ceiling.

Yeon Gaesomun Specialties

Yeon Gaesomun has four Specialties.

Ground Troop Defense

• Ground Troop HP +10%

• Ground Troop Defense +10%

This is a friendly troop buff rather than an enemy debuff.

It is secondary to his main Sub City role.

Suppress

• Enemy Troop HP -10%

This is an excellent broad debuff.

It reduces the HP of:

• Ground

• Mounted

• Ranged

• Siege

War God

• All Troops Attack +6%

This adds a small friendly troop Attack increase.

Again, this is secondary to Yeon Gaesomun's debuff role.

Battle of Sasu

• Enemy Ground Troop Attack -10%

• Enemy Mounted Troop Attack -10%

• Enemy Ranged Troop Attack -20%

• Enemy Siege Machine Attack -20%

Battle of Sasu is Yeon Gaesomun's standout Specialty.

It broadens his debuff profile beyond Ground and Mounted troops.

Yeon Gaesomun's Anti-Ground Debuffs

Ground Troops are Yeon Gaesomun's strongest target.

When fully Ascended and with Battle of Sasu developed, his own kit can reduce Enemy Ground:

Attack:

• -10% broad Attack from Dae Magniji

• -30% additional Ground Attack from Dae Magniji

• -10% from 4-Star Ascension

• -15% from 5-Star Ascension

• -10% from Battle of Sasu

Total:

• Enemy Ground Attack -75%

Defense:

• -15% from 1-Star

• -20% from 2-Star

• -25% from 5-Star

Total:

• Enemy Ground Defense -60%

HP:

• -10% from 1-Star

• -20% from 3-Star

• -20% from 4-Star

• -10% from Suppress

Total:

• Enemy Ground HP -60%

This is an extremely strong anti-Ground package.

Yeon Gaesomun's Anti-Mounted Debuffs

Mounted Troops also become a major target after Ascension.

Enemy Mounted Attack:

• -10% from Dae Magniji

• -10% from 4-Star Ascension

• -15% from 5-Star Ascension

• -10% from Battle of Sasu

Total:

• Enemy Mounted Attack -45%

Enemy Mounted Defense:

• -15% from 1-Star

• -20% from 2-Star

• -25% from 5-Star

Total:

• Enemy Mounted Defense -60%

Enemy Mounted HP:

• -10% from 1-Star

• -20% from 3-Star

• -20% from 4-Star

• -10% from Suppress

Total:

• Enemy Mounted HP -60%

This makes a fully developed Yeon Gaesomun much broader than his base skill initially suggests.

Yeon Gaesomun Against Ranged Troops

Ranged Troops receive:

• Enemy Attack -10% from Dae Magniji

• Enemy Attack -20% from Battle of Sasu

• Enemy HP -10% from Suppress

That gives:

• Enemy Ranged Attack -30%

• Enemy Ranged HP -10%

before debuff equipment.

He is not primarily an anti-Ranged specialist, but he still contributes.

Yeon Gaesomun Against Siege Machines

Siege receives the same broad effects:

• Enemy Attack -10% from Dae Magniji

• Enemy Attack -20% from Battle of Sasu

• Enemy HP -10% from Suppress

That gives:

• Enemy Siege Attack -30%

• Enemy Siege HP -10%

before equipment.

Dedicated anti-Siege Generals can provide stronger Siege-specific debuffs.

Why Yeon Gaesomun Works So Well in a Subordinate City

Subordinate City Generals accompany your Main City battles when the Sub City is linked to combat.

That allows their enemy debuffs to contribute without replacing your:

• attacking Main General

• Assistant General

• Wall General

Yeon Gaesomun can therefore weaken enemy troops while your stronger combat Generals handle the actual fighting.

That is exactly what a good Sub City Mayor should do.

Does Yeon Gaesomun Need Skill Books?

Not for his main role.

Skill Books do not increase the enemy debuffs that make Yeon Gaesomun valuable.

You can technically tailor books toward the troops trained inside the Subordinate City, but this should be a secondary concern.

Do not spend valuable development resources trying to turn him into a normal combat General.

His important systems are:

• Special Skill

• Ascension

• Specialties

• debuff equipment

Best Equipment for Yeon Gaesomun

For serious PvP use, prioritise debuff-focused equipment.

The goal is to add even more reductions to enemy:

• Attack

• Defense

• HP

Achaemenidae and other strong Sub City debuff equipment are far more useful than building Yeon Gaesomun like a normal Ground General.

Try to balance your entire Sub City lineup.

Do not simply stack the exact same debuff endlessly if your account has already reached the effective debuff cap against that stat.

Does Yeon Gaesomun Need Refines?

Refining Sub City equipment is usually a lower priority than acquiring the correct debuff pieces.

The main value comes from:

• equipment set effects

• enemy debuffs

• Ascension

• Specialties

Save expensive refinement investment for your core combat Generals unless you have a specific advanced Sub City strategy.

Yeon Gaesomun and Sub City Training Speed

At 2-Star Ascension, Yeon Gaesomun adds:

• Subordinate City Training Speed +20%

This is useful because Sub City troops can suffer heavy casualties during PvP.

Faster Training Speed helps replace those troops more quickly.

Yeon Gaesomun and Death-to-Survival

At 3-Star Ascension, Yeon Gaesomun provides:

• Subordinate City Death-to-Survival Rate +10%

This helps reduce permanent Sub City troop losses.

It is a useful supporting effect, although the debuffs remain the main reason to Ascend him.

Yeon Gaesomun for Ground PvP

Do not use Yeon Gaesomun as a normal Ground PvP Main.

Ground Troop Defense and War God provide some friendly troop buffs.

However, those numbers are tiny compared with proper modern Ground Generals.

His enemy debuffs are much more valuable from a Subordinate City.

Yeon Gaesomun for Main City Defense

Yeon Gaesomun should not replace your dedicated Wall General.

Instead, use him as a Sub City Mayor that participates in Main City defense.

That allows his debuffs to support your Wall setup without sacrificing your main Defense General.

Building a Debuff Team Around Yeon Gaesomun

Yeon Gaesomun works best when combined with other Subordinate City Generals that cover different weaknesses.

For example, your overall lineup should aim to reduce combinations of:

• Enemy Ground Attack

• Enemy Mounted Attack

• Enemy Ranged Attack

• Enemy Siege Attack

• Enemy Ground Defense and HP

• Enemy Mounted Defense and HP

• Enemy Ranged Defense and HP

• Enemy Siege Defense and HP

Yeon Gaesomun already covers Ground extremely well and Mounted strongly once Ascended.

Use other Mayors to improve:

• anti-Ranged coverage

• anti-Siege coverage

• broad all-troop debuffs

Is Yeon Gaesomun Still Relevant in 2026?

Yes.

Subordinate City debuff Generals age differently from normal PvP Generals.

Yeon Gaesomun still provides:

• major anti-Ground debuffs

• strong anti-Mounted debuffs after Ascension

• broad Enemy Attack reduction

• broad Enemy HP reduction

• extra anti-Ranged Attack

• extra anti-Siege Attack

That gives him a clear role even though many newer combat Generals have been released.

Is Yeon Gaesomun F2P Friendly?

Not especially.

Current acquisition sources are inconsistent.

Some databases display:

• 60,000,000 Gold

or Tavern-style metadata.

However, other current specialist databases explicitly say that Yeon Gaesomun is not available from the Tavern.

Official Evony acquisition information has historically included:

• General Portrait Exhibition

• Epic General recruitment

• Epic Historic General recruitment

• premium Historic General recruitment

and current specialist guides also list premium acquisition.

Because of these inconsistencies, do not assume he is a normal Tavern General.

How to Obtain Yeon Gaesomun

Yeon Gaesomun has been available through routes including:

• General Portrait Exhibition

• Epic Historic General recruitment

• premium General recruitment

• limited Historic General events

• Premium Packages

Current sources disagree about Tavern availability.

The safest approach is to check the live recruitment pool rather than spending heavily on Tavern refreshes expecting him to appear.

Yeon Gaesomun and General Hall

Yeon Gaesomun is required for:

• Battle-tested General

in General Hall II.

That gives him additional collection value even if your Sub City lineup later changes.

Is Yeon Gaesomun Worth Ascending?

Yes, if you use him as a long-term Subordinate City Mayor and can obtain fragments.

His Ascension adds major reductions to:

• Enemy Ground Attack

• Enemy Ground Defense

• Enemy Ground HP

• Enemy Mounted Attack

• Enemy Mounted Defense

• Enemy Mounted HP

while also adding:

• Sub City Training Speed

• Sub City Death-to-Survival

This is an unusually strong Ascension tree for a debuff General.

However, accessibility matters.

If duplicate fragments are extremely difficult to obtain, another easier-to-Ascend Sub City General may provide better practical value.

Is Yeon Gaesomun Worth Specialties?

Yes, if he is part of your permanent Sub City lineup.

Suppress adds:

• Enemy Troop HP -10%

Battle of Sasu adds:

• Enemy Ground Attack -10%

• Enemy Mounted Attack -10%

• Enemy Ranged Attack -20%

• Enemy Siege Attack -20%

These are valuable PvP debuffs.

However, Runestones are expensive.

Develop your essential combat Generals first unless debuff optimisation is already a major priority.

Is Yeon Gaesomun Worth Investing In?

Yeon Gaesomun is worth investing in if:

• you actively use Subordinate Cities in PvP

• Ground attackers are a major threat

• Mounted attackers are a major threat

• you already own him

• you can obtain Ascension fragments

• you need stronger enemy Attack debuffs

• you are building a serious long-term debuff lineup

He is less urgent if:

• your core combat Generals are unfinished

• you rarely use linked Subordinate Cities

• duplicate fragments are extremely difficult to obtain

• your Blood of Ares is limited

• your Runestones are limited

TEBA 2026 Reality Check

Yeon Gaesomun can look like a simple anti-Ground General if you only read his base skill.

That undersells him.

His base skill already gives:

• Enemy Ground Attack -40%

• Enemy Mounted Attack -10%

• Enemy Ranged Attack -10%

• Enemy Siege Attack -10%

Once fully Ascended and specialised, his personal debuff package can become much broader.

Against Ground he can reach approximately:

• Attack -75%

• Defense -60%

• HP -60%

Against Mounted he can reach approximately:

• Attack -45%

• Defense -60%

• HP -60%

before equipment and other account debuffs.

That makes Ground his biggest target, but Mounted becomes an important secondary target once Ascension is developed.

His biggest weakness is not effectiveness.

It is acquisition and Ascension difficulty.

TEBA Verdict

Yeon Gaesomun is a specialist Subordinate City PvP General built around enemy debuffs.

His base Special Skill provides:

• Enemy Troop Attack -10%

• additional Enemy Ground Attack -30%

giving Ground:

• Enemy Ground Attack -40%

immediately.

His Ascension then adds major:

• Enemy Ground Attack reduction

• Enemy Ground Defense reduction

• Enemy Ground HP reduction

• Enemy Mounted Attack reduction

• Enemy Mounted Defense reduction

• Enemy Mounted HP reduction

• Sub City Training Speed

• Sub City Death-to-Survival

while his Specialties add:

• Enemy Troop HP -10%

• Enemy Ground Attack -10%

• Enemy Mounted Attack -10%

• Enemy Ranged Attack -20%

• Enemy Siege Attack -20%

His biggest strengths are:

• exceptional anti-Ground debuffing

• strong anti-Mounted debuffing after Ascension

• broad enemy Attack reduction

• useful anti-Ranged and anti-Siege support

• excellent long-term Sub City role

• General Hall value

His biggest weakness is accessibility.

For players who already own Yeon Gaesomun and can obtain enough fragments to Ascend him, he remains a highly useful Subordinate City Mayor in 2026.
