Yi Sun-sin Specialties

Yi Sun-sin has four Specialties.

Mounted Troop Assault

• Mounted Troop Attack +10%

• Mounted Troop HP +10%

This is one reason Yi Sun-sin leans slightly more toward Mounted defense.

Fortification

Applied to Main City Defense General:

• In-City Troop Attack +6%

This adds another broad defensive attack bonus.

War God

• All Troops Attack +6%

This gives another universal offensive increase.

Battle of Myeongnyang

• Ground Troop Attack +20%

• Mounted Troop Attack +20%

• Enemy Ground Troop Attack -10%

• Enemy Mounted Troop Attack -10%

Battle of Myeongnyang is Yi Sun-sin's standout Specialty.

It adds both:

• direct Ground/Mounted damage

• anti-Ground/Mounted debuffing

Yi Sun-sin and Mounted Defense

Mounted is one of Yi Sun-sin's strongest defensive troop types.

His kit can provide:

• Mounted Attack

• Mounted Defense

• Mounted HP

• additional Mounted Attack through Specialties

• Enemy Mounted Attack reduction

This makes him particularly useful against:

• Ground-heavy enemy marches

because Mounted Troops naturally perform well against Ground Troops.

Yi Sun-sin and Ground Defense

Ground also receives very strong support.

His kit provides:

• Ground Attack

• Ground Defense

• Ground HP

• Enemy Ground Attack reduction

Ground is especially useful for absorbing pressure and supporting a layered defensive setup.

Yi Sun-sin and Hospital Capacity

At 2-Star Ascension, Yi Sun-sin gains:

• Hospital Capacity +20%

This is very valuable for city defense.

A larger Hospital allows more wounded troops to survive before losses become more severe.

For large defensive accounts, Hospital Capacity can be just as important as raw troop buffs.

Best Skill Books for Yi Sun-sin

For a Mounted-focused defense, a strong setup is:

• Lv4 Mounted Troop Attack

• Lv4 Mounted Troop Defense

• Lv4 Mounted Troop HP

This creates a balanced Mounted defense.

Ground-Focused Skill Book Build

If your city relies more heavily on Ground Troops, use:

• Lv4 Ground Troop Attack

• Lv4 Ground Troop Defense

• Lv4 Ground Troop HP

This strengthens Ground survivability and damage.

Should Yi Sun-sin Use Mixed Skill Books?

Usually no.

Although he buffs both Ground and Mounted Troops, mixing:

• Ground Attack

• Mounted Attack

• Ground HP

• Mounted Defense

across only three Skill Book slots can dilute the build.

It is usually better to choose one primary defensive troop type.

For most Yi Sun-sin setups:

• Mounted first

• Ground second

is the cleaner approach.

Best Assistant Generals for Yi Sun-sin

A strong Assistant should add:

• In-City Troop buffs

• Mounted Attack, Defense or HP

• Ground Attack, Defense or HP

• enemy debuffs

• Hospital or defensive utility

without disabling Commander.

Always test the exact Main and Assistant pairing in-game before heavy investment.

Equipment and Refines

For Mounted-focused defense, prioritise:

Spear

• Mounted Troop Attack % x4

Ring

• Mounted Troop Attack % x4

Armor

• Mounted Troop Defense % x4

Boots

• Mounted Troop Defense % x4

Helmet

• Mounted Troop HP % x4

Leg Armor

• Mounted Troop HP % x4

For Ground-focused defense, switch these to the equivalent Ground stats.

Yi Sun-sin Against Ground Attacks

This is one of his best defensive matchups.

Mounted Troops naturally perform well against Ground Troops.

Yi Sun-sin supports Mounted with:

• Attack

• Defense

• HP

while Battle of Myeongnyang can also reduce:

• Enemy Ground Attack -10%

This gives him useful anti-Ground defensive value.

Yi Sun-sin Against Mounted Attacks

Yi Sun-sin also reduces:

• Enemy Mounted Attack -10%

through Battle of Myeongnyang.

However, his defense is not specifically designed as a hard Mounted counter.

The overall effectiveness depends heavily on your troop layers and defensive composition.

Yi Sun-sin Against Ranged Attacks

Ranged Troops are not directly debuffed by Yi Sun-sin.

His Ground and Mounted buffs can still contribute defensively, but he does not have strong anti-Ranged mechanics.

Dedicated anti-Ranged Wall Generals may perform better in that matchup.

Yi Sun-sin Against Siege Attacks

Yi Sun-sin also lacks strong Siege-specific debuffs.

His broad In-City Troop Attack still helps, but modern Wall Generals with:

• Siege debuffs

• Ranged/Siege survivability

• broad enemy reductions

can offer more specialised value.

Is Yi Sun-sin Still Relevant in 2026?

Yes, but mainly for specialised Ground/Mounted defense.

He still provides:

• strong Ground Attack

• strong Mounted Attack

• Ground and Mounted Defense

• Ground and Mounted HP

• Hospital Capacity

• broad In-City Attack

• anti-Ground and anti-Mounted Attack debuffs

However, newer Wall Generals now often provide:

• broader troop coverage

• stronger enemy debuffs

• larger defensive buff packages

• Covenants

• Skins

• more flexible mixed-defense scaling

Yi Sun-sin is therefore strongest if:

• you already have him developed

• your defense is Ground/Mounted heavy

• you value Mounted defense specifically

Is Yi Sun-sin F2P Friendly?

Not especially.

Current specialist sources most consistently list Yi Sun-sin as:

• Premium Packages

Some databases display a nominal Gold value of:

• 50,000,000 Gold

but current Tavern availability is inconsistent across sources.

Treat Yi Sun-sin as premium or event-based unless the live game shows otherwise.

How to Obtain Yi Sun-sin

Yi Sun-sin is most consistently listed through:

• Premium Packages

• premium Historic General recruitment

• limited General events

Some databases display:

• 50,000,000 Gold

or Tavern-style metadata.

Because current sources conflict, verify the live recruitment pool before spending specifically for him.

Is Yi Sun-sin Worth Ascending?

Yes, if he is your long-term Wall General.

His Ascension adds:

• Ground Defense

• Ground HP

• Mounted Defense

• Mounted HP

• Ground Attack

• Mounted Attack

• Hospital Capacity

• broad In-City Attack

These are meaningful defensive upgrades.

However, duplicate fragments can be difficult to obtain.

Blood of Ares is also valuable.

If you already own a stronger modern Wall General, compare the long-term return before heavily Ascending Yi Sun-sin.

Is Yi Sun-sin Worth Specialties?

Yes, if he remains central to your defense.

Battle of Myeongnyang adds:

• Ground Attack +20%

• Mounted Attack +20%

• Enemy Ground Attack -10%

• Enemy Mounted Attack -10%

while his other Specialties add:

• Mounted Attack

• Mounted HP

• In-City Attack

• All Troop Attack

However, Runestones are expensive.

Do not fully max him from zero if your account is already moving toward a stronger modern Wall setup.

Is Yi Sun-sin Worth Investing In?

Yi Sun-sin is worth investing in if:

• you already own him

• your city defense is Ground/Mounted heavy

• you rely on Mounted defense against Ground attacks

• you value Hospital Capacity

• you can realistically obtain Ascension fragments

He is less attractive if:

• you are building a brand-new endgame defense from zero

• your defense is primarily Ranged/Siege

• you already own a stronger modern Wall General

• duplicate fragments are difficult

• Blood of Ares is limited

• Runestones are limited

TEBA 2026 Reality Check

Yi Sun-sin is a specialised Wall General.

His biggest strength is not universal defense.

It is:

• Ground

• Mounted

A developed Yi Sun-sin can provide substantial:

• In-City Ground Attack

• In-City Mounted Attack

• Ground/Mounted Defense

• Ground/Mounted HP

• Hospital Capacity

• Enemy Ground/Mounted Attack reduction

That still has real value.

However, modern Wall Generals often provide stronger all-troop coverage and broader enemy debuffs.

So if Yi Sun-sin is already heavily developed, he remains useful.

If you are starting a completely new defense from zero, compare him carefully against newer Wall options first.

TEBA Verdict

Yi Sun-sin is a specialist Main City Defense General built around Ground and Mounted troops.

His base Special Skill provides:

• In-City Troop Attack +10%

• additional In-City Ground Attack +15%

• additional In-City Mounted Attack +15%

while he is the Main City Defense General.

His Ascension then adds:

• Ground Defense

• Ground HP

• Mounted Defense

• Mounted HP

• Ground Attack

• Mounted Attack

• Hospital Capacity +20%

• another broad In-City Attack +15%

while Battle of Myeongnyang adds:

• Ground Attack +20%

• Mounted Attack +20%

• Enemy Ground Attack -10%

• Enemy Mounted Attack -10%

His biggest strengths are:

• strong Ground/Mounted defense

• strong Ground/Mounted Attack

• useful Hospital Capacity

• straightforward defensive identity

• effective Mounted defense against Ground-heavy attacks

His biggest weaknesses are:

• limited anti-Ranged support

• limited anti-Siege support

• premium/event accessibility

• stronger modern Wall Generals now existing

For players who already own and have developed Yi Sun-sin, he remains a useful Ground/Mounted Wall General in 2026.

For players starting from zero, compare newer Main City Defense Generals before committing large amounts of Blood of Ares, Runestones or premium resources.
