Is Eulji Mundeok Good in Evony?

Yes.

Eulji Mundeok is one of the most practical Academy Duty Generals because his Special Skill provides:

• Research Speed +20%

That gives immediate value every time you start new research.

His Ascension and Specialties can increase that Research Speed further while also adding passive defensive buffs.

Eulji Mundeok Best Role

Best Role: Academy Duty Officer

Also Good For:

• long-term account progression

• speeding up Military research

• speeding up Advancement research

• speeding up Defense research

• Ranged PvP

• Ground PvP

• Mounted PvP

Although some of Eulji Mundeok's Specialties contain combat or Sub City effects, his overall kit is overwhelmingly designed around the Academy.

Eulji Mundeok Special Skill

Eulji Mundeok's Special Skill is:

National Hero

When Eulji Mundeok is the Academy Officer:

• Research Speed +20%

This is the main reason to use him.

Research becomes increasingly expensive and time-consuming as your account develops.

A large Research Speed bonus can save a substantial amount of time and Speedups over the life of an account.

Why Research Speed Matters

Research affects almost every major part of Evony.

It can improve:

• troop Attack

• troop Defense

• troop HP

• March Size

• March Speed

• Gathering

• Construction

• Training

• healing

• resource production

• military systems

• city defense

The faster you complete research, the faster your entire account improves.

That is why Eulji Mundeok remains useful long after many older combat Generals have been power-crept.

Eulji Mundeok Ascension

Ascending Eulji Mundeok adds both Research Speed and passive defensive value.

1 Star

When Eulji Mundeok is the Academy Officer:

• In-City Ground Troop Defense +10%

• In-City Ground Troop HP +10%

• In-City Mounted Troop Defense +10%

• In-City Mounted Troop HP +10%

This gives immediate survivability to Ground and Mounted Troops inside the city.

2 Stars

• Research Speed +8%

This is one of his most important Ascension upgrades.

It directly improves his primary role.

3 Stars

• In-City Ranged Troop Defense +20%

• In-City Ranged Troop HP +15%

• In-City Siege Machine Defense +20%

• In-City Siege Machine HP +15%

This adds substantial defensive support to Ranged and Siege formations.

When Eulji Mundeok is the Academy Officer:

• In-City Ground Troop Defense +15%

• In-City Ground Troop HP +15%

• In-City Mounted Troop Defense +15%

• In-City Mounted Troop HP +15%

This further strengthens Ground and Mounted survivability.

• In-City Ranged Troop Attack +10%

• In-City Siege Machine Attack +10%

• In-City Ranged Troop Defense +15%

• In-City Siege Machine Defense +15%

• In-City Ranged Troop HP +15%

• In-City Siege Machine HP +15%

The fifth star gives a strong final block of Ranged and Siege defensive support.

Eulji Mundeok Specialties

Eulji Mundeok has four Specialties.

Ranged Troop Formation

• Ranged Troop Attack +10%

• Ranged Troop Defense +10%

This is secondary to his Academy role.

Do not build Eulji Mundeok as a Ranged PvP General because of this Specialty.

Pacify

Applied to Subordinate City Mayor:

• Subordinate City Gold Production Speed +36%

• Subordinate City Construction Speed +36%

This Specialty does not support his main Academy role.

Do not move him into a Subordinate City simply to activate it unless you have no better use for him.

Sage

Applied to Academy Officer:

• Research Speed +10%

This directly improves his core purpose.

Battle of Salsu River

Applied to Academy Officer:

• Research Speed +20%

Battle of Salsu River is Eulji Mundeok's standout Specialty.

It provides another major Research Speed increase.

How Much Research Speed Can Eulji Mundeok Add?

Eulji Mundeok gains:

• Research Speed +20% from National Hero

• Research Speed +8% from 2-Star Ascension

• Research Speed +10% from Sage

• Research Speed +20% from Battle of Salsu River

That gives:

58% Research Speed

from his own fully developed Academy-focused kit.

This is the defining reason to use him.

Eulji Mundeok and In-City Ground Troops

Ground Troops gain defensive support through Ascension.

Eulji Mundeok can add:

• In-City Ground Defense +10% at 1-Star

• In-City Ground HP +10% at 1-Star

• In-City Ground Defense +15% at 4-Star

• In-City Ground HP +15% at 4-Star

That gives:

• In-City Ground Defense +25%

• In-City Ground HP +25%

from Ascension.

Eulji Mundeok and In-City Mounted Troops

Mounted Troops receive the same Ascension support.

That gives:

• In-City Mounted Defense +25%

• In-City Mounted HP +25%

when fully Ascended.

This gives useful passive city-defense value from an economy-focused Duty slot.

Eulji Mundeok and In-City Ranged Troops

Ranged Troops receive even stronger late-Ascension support.

At 3-Star:

• In-City Ranged Defense +20%

• In-City Ranged HP +15%

At 5-Star:

• In-City Ranged Attack +10%

• In-City Ranged Defense +15%

• In-City Ranged HP +15%

That gives:

• In-City Ranged Attack +10%

• In-City Ranged Defense +35%

• In-City Ranged HP +30%

from Ascension.

Eulji Mundeok and In-City Siege Machines

Siege receives the same 3-Star and 5-Star Ascension support.

That gives:

• In-City Siege Attack +10%

• In-City Siege Defense +35%

• In-City Siege HP +30%

when fully Ascended.

This makes Eulji Mundeok especially useful for accounts with large Ranged and Siege defensive layers.

Does Eulji Mundeok Need Skill Books?

No.

Eulji Mundeok is a Duty Officer.

Skill Books do not improve the Academy bonuses that make him valuable.

Do not waste Skill Books trying to turn him into:

• Ranged PvP Main

• Monster Hunter

• Wall General

• Sub City General

His value comes from:

• National Hero

• Duty rank

• Ascension

• Specialties

Does Eulji Mundeok Need Equipment?

Not for normal Academy Duty.

Combat equipment does not improve his core Research Speed bonuses while he is assigned to the Academy.

The priority should be:

• General level

• cultivation

• Academy Duty requirements

rather than expensive combat equipment.

What Should You Cultivate on Eulji Mundeok?

Cultivate Eulji Mundeok to meet Academy Duty requirements.

Do not build him like a combat General.

Your goal is to reach the highest possible Duty rank.

Higher Duty ranks provide additional Academy benefits alongside his own Special Skill and Specialties.

Eulji Mundeok for Research Progression

This is his main job.

Use Eulji Mundeok to accelerate:

• Military research

• Defense research

• Advancement research

• resource research

• troop research

• late-game technologies

Research times become enormous at higher levels.

His percentage-based Research Speed therefore becomes increasingly valuable as your account progresses.

When Should You Assign Eulji Mundeok?

Ideally, keep Eulji Mundeok assigned to the Academy whenever you are actively researching.

Make sure his Academy Duty is active before starting long research projects.

This is especially valuable for:

• very long Military researches

• high-level troop buffs

• March Size technologies

• late-game Academy progression

Eulji Mundeok During PvP

Eulji Mundeok is not a Wall General.

However, Ascension gives him meaningful passive defensive value while he remains in the Academy.

He can support:

• Ground

• Mounted

• Ranged

• Siege

through In-City Defense and HP buffs.

Ranged and Siege also gain:

• In-City Attack +10%

at 5-Star.

That means he can continue helping your defense without leaving the Academy.

Should Eulji Mundeok Be Used as a Sub City Mayor?

Usually no.

Pacify provides:

• Sub City Gold Production

• Sub City Construction Speed

when he is Mayor.

However, moving him out of the Academy sacrifices:

• National Hero

• Sage

• Battle of Salsu River

• Academy-specific Ascension buffs

His Academy role is much stronger overall.

Use a dedicated Sub City General instead.

Should Eulji Mundeok Be Used for Ranged PvP?

No.

Ranged Troop Formation provides:

• Ranged Attack +10%

• Ranged Defense +10%

but that is nowhere near enough to make him a serious Ranged PvP General.

Modern Ranged Generals provide vastly larger combat packages.

Leave Eulji Mundeok in the Academy.

Is Eulji Mundeok Still Relevant in 2026?

Yes.

Duty Generals age very well because their value does not depend on keeping up with combat power creep.

Eulji Mundeok still provides:

• large Research Speed bonuses

• Ground defensive support

• Mounted defensive support

• Ranged defensive support

• Siege defensive support

• Tavern accessibility

As long as your account still has important research to complete, he remains useful.

Is Eulji Mundeok F2P Friendly?

Yes.

Eulji Mundeok is available from the Tavern.

Current sources list his cost at:

• 45,000,000 Gold

That makes him realistic for F2P and low-spend players to obtain.

It also makes duplicate copies for Ascension much more achievable than with premium Duty Generals.

How to Obtain Eulji Mundeok

Eulji Mundeok can be recruited from the Tavern.

Current sources list his cost at:

• 45,000,000 Gold

This accessibility is one of his biggest advantages.

Is Eulji Mundeok Worth Ascending?

Yes, if he is your long-term Academy Officer.

His Ascension adds:

• Research Speed +8%

• Ground Defense and HP

• Mounted Defense and HP

• Ranged Defense and HP

• Siege Defense and HP

• Ranged Attack

• Siege Attack

The 2-Star Ascension is particularly valuable because it directly increases Research Speed.

However, Blood of Ares is valuable.

Your main PvP and Wall Generals may deserve priority first.

Is Eulji Mundeok Worth Specialties?

Yes, eventually.

Sage adds:

• Research Speed +10%

Battle of Salsu River adds:

• Research Speed +20%

That is another:

30% Research Speed

from Specialties alone.

However, Runestones are expensive.

For most accounts, core combat Generals should receive priority before fully maxing a Duty Officer.

Is Eulji Mundeok Worth Investing In?

Eulji Mundeok is worth investing in if:

• you still have large amounts of research remaining

• Research Speed is a major bottleneck

• you want an accessible Academy Officer

• you are F2P or low-spend

• you plan to keep him long term

• you want extra passive city-defense buffs

He is less urgent if:

• most important research is already complete

• your primary PvP Generals are unfinished

• your Blood of Ares is limited

• your Runestones are limited

TEBA 2026 Reality Check

Eulji Mundeok should not be judged as a combat General.

His job is research.

A fully developed Eulji Mundeok can provide:

• Research Speed +58%

• In-City Ground Defense +25%

• In-City Ground HP +25%

• In-City Mounted Defense +25%

• In-City Mounted HP +25%

• In-City Ranged Attack +10%

• In-City Ranged Defense +35%

• In-City Ranged HP +30%

• In-City Siege Attack +10%

• In-City Siege Defense +35%

• In-City Siege HP +30%

from his own developed Academy kit.

That is excellent passive value from one Duty slot.

TEBA Verdict

Eulji Mundeok is an accessible specialist Academy Duty Officer built around Research Speed.

His base Special Skill provides:

• Research Speed +20%

while he is Academy Officer.

His Ascension then adds:

• another Research Speed +8%

• Ground and Mounted defensive support

• Ranged and Siege defensive support

• In-City Ranged Attack

• In-City Siege Attack

while Sage and Battle of Salsu River add:

• another Research Speed +30%

That gives Eulji Mundeok:

• Research Speed +58%

from his own fully developed Academy-focused kit.

His biggest strengths are:

• excellent Research Speed

• useful passive city defense

• Tavern accessibility

• realistic F2P Ascension

• simple long-term Duty value

His biggest limitation is that he offers very little outside Academy Duty.

For F2P and low-spend accounts, Eulji Mundeok remains a very practical Academy Duty Officer in 2026.
