Osman I ROK Guide: Best Talent Tree, Skills and Pairings

Osman I is an Epic commander in Rise of Kingdoms with Leadership, Conquering, and Skill talent trees. He is one of the more accessible early-game nukers because he combines strong single-target Skill Damage with additional follow-up damage and increased troop capacity.

Unlike commanders built around Infantry, Cavalry, or Archers, Osman does not require one specific troop type. That flexibility makes him easy to use on a young account, especially as a secondary commander behind a troop-specific primary such as Sun Tzu, Pelagius, or Bjorn Ironside.

Osman eventually falls behind modern Legendary commanders, but that does not make him useless. He remains inexpensive to expertise, effective during early kingdom development, and useful as a secondary damage commander after his period as a primary march ends.

Is Osman I Good in Rise of Kingdoms?

Yes, particularly during the early stages of an account.

Osman has several advantages that are valuable before your Legendary roster becomes fully developed:

• Strong single-target active Skill Damage
• Additional damage after every active skill
• Up to 10% additional troop capacity
• No required troop type
• Access to the Skill talent tree
• Easy Epic-sculpture progression
• Useful secondary-commander value

However, he also has important limitations.

Osman has no healing, shield, major permanent damage reduction, or reliable AOE. Therefore, modern Legendary marches eventually outperform him in both damage and survivability.

Osman I Quick Overview

How to Get Osman I

Osman I is the starting commander of the Ottoman Empire civilization.

He can also be developed through normal Epic commander progression, making him considerably easier to expertise than a Legendary commander.

Because Osman is Epic, there is little reason to spend premium commander resources trying to force an unusual partial skill configuration. Let regular Epic sculptures complete him over time.

Best Osman I Talent Tree

Osman has three talent trees:

• Leadership
• Conquering
• Skill

For normal PvP, his best talents come primarily from Skill and Leadership.

Use Conquering mainly when you specifically want Osman to lead an early city rally.

Osman I Open-Field Talent Tree

The open-field Osman build should focus on active-skill cycling first, then use Leadership talents for additional durability and troop strength.

Rejuvenate

Rejuvenate is the most important early talent for a Skill-based Osman build.

It returns Rage after the primary and secondary commanders use their active skills. Faster Rage generation means more casts of The Empire Awakens and more Sword of Osman follow-up hits.

Burning Blood

Burning Blood adds more Rage generation while Osman is being attacked.

Osman should not deliberately tank multiple marches, but additional Rage during normal trades supports his main damage cycle.

All For One

All For One improves the active skill of the secondary commander after Osman uses his skill.

This fits commanders such as Sun Tzu, Pelagius, Boudica, and other skill-focused partners.

Tactical Mastery

Tactical Mastery increases active Skill Damage and directly improves The Empire Awakens.

Feral Nature

If your level and talent path allow it, Feral Nature provides another Rage-generation mechanic and can further accelerate Osman’s skill cycle.

Strategic Prowess

Leadership talents can compensate for some of Osman’s limited natural durability.

Strategic Prowess provides temporary Defense after using an active skill, creating useful synergy with Osman’s frequent skill cycle.

Fresh Recruits

Fresh Recruits increases troop capacity.

This combines naturally with Sultan’s Glory and allows Osman to field an even larger march.

Osman I Rally Talent Tree

The rally build is designed only for early city attacks.

Use the Conquering tree for talents that improve city attacks and rally performance, while still taking important Skill talents such as Rejuvenate.

Useful Conquering talents include:

• Entrenched
• Marionette
• Signal Flare
• Moment of Triumph
• Buckler Shield
• Tear of Blessing
• Meteor Shower when your build reaches it

However, city attacks can create permanent troop deaths for the attacker. Do not use an Osman rally simply because the talent tree exists.

Scout the target, consider reinforcements and technology, and use a more appropriate rally commander once your kingdom develops stronger options.

Should Osman I Be Primary or Secondary?

Osman is often better as a secondary commander.

The reason is simple: he has useful skills but no Infantry, Cavalry, or Archer talent tree.

If your march uses one specific troop type, a specialized primary can provide better troop statistics while Osman contributes his damage from the secondary position.

Use Osman primary mainly when you specifically need his Skill, Leadership, or Conquering talent setup.

Best Formation for Osman I

Wedge Formation

Wedge is the most natural formation when Osman is being used as primary for a Skill Damage-focused march.

The Empire Awakens and Sword of Osman make active-skill pressure the center of his combat identity.

However, formation choice should still consider your available armaments. A strong alternative formation with substantially better attributes can outperform weak Wedge armaments.

Useful Armament Attributes

• Health
• Defense
• Skill Damage
• All Damage
• Damage Reduction
• Attack
• March Speed

If Osman is secondary, build the formation around the primary commander instead.

Best Osman I Skill Order

The old skill progression can be simplified.

Osman is Epic, which means there is little need to create a complicated permanent partial build.

Step 1: Max The Empire Awakens

Keep Osman at one star until The Empire Awakens reaches level five.

This gives him the full 850 direct damage factor before other skills enter the upgrade pool.

Step 2: Continue Natural Epic Progression

Once the first skill is maxed, unlock the remaining skills and keep upgrading Osman as Epic sculptures become available.

All three passive skills have useful effects:

• Radiance of Bursa supports early city attacks.
• Sword of Osman adds direct follow-up damage.
• Sultan’s Glory increases troop capacity.

Step 3: Reach 5-5-5-5

Expertise is a realistic long-term target because Osman is Epic.

You do not need to rush him with premium resources, but there is also little reason to intentionally leave him unfinished once Epic sculptures become plentiful.

Osman I Skills Explained

The Empire Awakens

Skill type: Active
Rage requirement: 1,000

The Empire Awakens deals direct damage to one enemy troop.

There are no special conditions or complicated effects. Osman builds Rage, casts his active skill, and applies direct single-target damage.

This simplicity is one reason he works so well for beginners.

Radiance of Bursa

After Osman has attacked a city for more than 30 seconds, troops led by him receive increased Attack for 120 seconds.

This is Osman’s most situational skill.

It provides no direct benefit during ordinary open-field fighting. Therefore, do not evaluate Osman purely from the strength of every skill in his kit. His first, third, fourth, and expertise effects matter more to normal PvP.

Sword of Osman

After Osman uses an active skill, Sword of Osman deals additional direct damage to the target on the following turn.

This skill explains why Rage generation matters so much.

Every additional active-skill cycle can produce another The Empire Awakens followed by another Sword of Osman hit.

Sultan’s Glory

Sultan’s Glory increases troop capacity.

Troop capacity is valuable because it increases the number of units contributing to a march.

A larger march generally produces more total damage and remains effective longer before troop strength becomes too depleted.

Rising Empire

Rising Empire enhances The Empire Awakens.

Once expertised, the active skill’s direct damage factor increases from 850 to 1,100.

Combined with a maximum Sword of Osman, one complete active-skill sequence can produce:

• 1,100 direct damage factor from The Empire Awakens
• 400 follow-up damage factor from Sword of Osman

That straightforward burst is particularly strong during early kingdom development when enemy marches have less optimized commanders, equipment, and technology.

Best Osman I Pairings

Sun Tzu and Osman I

Recommended: Sun Tzu primary, Osman secondary

This is one of the most practical Epic combinations for an early Infantry player.

Sun Tzu supplies AOE, Rage generation, and a stronger Infantry-oriented primary setup. Osman adds focused single-target damage behind him.

Bjorn Ironside and Osman I

Recommended: Bjorn primary, Osman secondary

Bjorn is another accessible Infantry option and can increase the Skill Damage taken by his target.

This gives Osman a stronger window for The Empire Awakens and Sword of Osman.

Pelagius and Osman I

Recommended: Pelagius primary, Osman secondary

Pelagius provides Cavalry-specific talents, Rage restoration, healing, and additional combat statistics.

Osman then contributes his burst without forcing the Cavalry march to use a Leadership talent tree.

Boudica and Osman I

Best for: Developing accounts

Boudica combines single-target damage, utility, and Peacekeeping access.

The pairing is flexible for players who are still using the same commanders across Barbarian farming and occasional early PvP.

However, Boudica’s Peacekeeping talents should only be used when she is actually farming neutral units.

Aethelflaed and Osman I

Recommended: Aethelflaed primary, Osman secondary

Aethelflaed provides AOE debuffs and works naturally with mixed troop marches.

Osman contributes focused damage after her debuffs have weakened the target.

Scipio Africanus and Osman I

Best for: Large early mixed marches

Both commanders can contribute troop-capacity value.

The combination lacks the offensive synergy of Sun Tzu or Bjorn, but it can be useful while a new account is still developing specialized marches.

Yi Seong-Gye and Osman I

Best for: Older developing rosters

YSG provides strong AOE and Skill Damage value, while Osman adds focused damage.

However, an account with enough Legendary depth to develop stronger YSG pairings will normally move Osman elsewhere.

Genghis Khan and Osman I

Recommended: Genghis Khan primary, Osman secondary

An already-developed Genghis Khan can combine with Osman for heavy single-target burst.

Genghis supplies Cavalry talents and rapid skill cycling, while Osman adds another active and follow-up damage sequence.

This is now a legacy combination. Use it when the commanders already exist rather than building Genghis specifically for Osman.

What Troops Should Osman I Use?

Osman does not require a specific troop type.

Instead, use the troop type that matches the primary commander.

Do not use mixed troops simply because Osman has Leadership talents. If his primary partner rewards a specific troop type, follow that specialization.

Best Equipment for Osman I

Equipment should follow the march’s actual troop type rather than Osman himself.

For example:

• Sun Tzu or Bjorn primary: use Infantry equipment.
• Pelagius or Genghis primary: use Cavalry equipment.
• An Archer primary: use Archer equipment.
• A mixed Leadership march: prioritize broadly useful statistics and the primary commander’s needs.

Stat Priority

1. Health
2. Defense
3. Skill Damage
4. Damage Reduction
5. Attack
6. March Speed

Osman already contributes considerable burst damage but very little durability. Therefore, improving Health and Defense often produces better practical trades than stacking Attack alone.

Do not craft expensive equipment specifically for Osman. Build equipment that will remain useful after a stronger commander replaces him.

How to Use Osman I in Open Field

Let Tankier Marches Engage First

Osman is a damage dealer, not a frontline tank.

Allow sturdier allied marches to make initial contact before moving your Osman march into range.

Focus One Target

Osman does not have AOE.

Pick an isolated, damaged, or alliance-focused target and use The Empire Awakens plus Sword of Osman to increase concentrated pressure.

Prioritize Rage Generation

Every active-skill cycle creates both the active hit and the Sword of Osman follow-up.

This is why Rejuvenate, Burning Blood, and Rage-supporting primary commanders work well with him.

Avoid Being Surrounded

Osman lacks strong anti-swarm mechanics.

If several enemies begin focusing his march, retreat rather than remaining for another damage cycle.

Refresh the March Early

Troop capacity makes Osman stronger at the beginning of a fight, but that advantage declines as units become severely wounded.

Return and refresh the march once its damage output begins falling significantly.

Osman I Rally and City Attack Tips

Osman can lead city attacks during early kingdom development because he has the Conquering tree and Radiance of Bursa.

However, city attacks carry significantly more risk than normal open-field fighting.

Before launching a rally:

• Scout the city.
• Check the defender’s commander setup.
• Consider the target’s technology and troop tier.
• Watch for alliance reinforcements.
• Confirm your alliance can fill the rally.
• Decide whether the expected result justifies the troop losses.

Do not use Osman as a serious late-game rally commander. His Conquering talents are an early-game option, not a reason to keep him leading rallies indefinitely.

Osman I Strengths and Weaknesses

Common Osman I Mistakes

• Using Osman as a frontline tank: His defensive kit is too limited.
• Ignoring the first-skill rule: Max The Empire Awakens before unlocking every skill.
• Overcomplicating partial skill builds: He is Epic and can naturally reach 5-5-5-5.
• Building Conquering for open field: Skill and Leadership are more useful there.
• Keeping Osman primary behind a troop specialist: Let Sun Tzu, Pelagius, Bjorn, or another appropriate commander supply the troop talents.
• Using random mixed troops: Match troops to the primary commander’s skills.
• Building only Attack: Health and Defense improve Osman’s field lifespan.
• Forcing city rallies: Rallying cities can cause expensive troop losses.
• Expecting AOE: Osman focuses on one target.
• Staying while swarmed: He lacks anti-swarm protection.
• Crafting expensive Osman-specific equipment: Use transferable troop equipment.
• Expecting late-game meta performance: Osman is an early-game Epic commander and later backup option.

FAQ

Is Osman I good in ROK?

Yes. Osman I is a useful early-game Epic nuker with good single-target Skill Damage and additional troop capacity. He eventually falls behind modern Legendary commanders.

What is the best Osman talent tree?

Use Skill and Leadership for normal open-field combat, prioritizing Rage generation through talents such as Rejuvenate. Use Conquering mainly for early city rallies.

What is the best Osman I skill order?

Max The Empire Awakens first at 5-1-1-1. After that, continue developing him naturally toward 5-5-5-5 because Osman is an accessible Epic commander.

Should Osman I be primary or secondary?

Osman is often better as secondary behind a commander with a troop-specific talent tree. Use him as primary when you specifically need his Skill, Leadership, or early Conquering talents.

What is the best Osman I pairing?

Sun Tzu and Bjorn Ironside are strong Epic options for Infantry players, while Pelagius works well for Cavalry. Aethelflaed is useful for mixed troops, and older Legendary commanders can also use Osman as a temporary secondary.

What troop type should Osman use?

Osman has no mandatory troop type. Match the troops to the primary commander. Use Infantry behind Sun Tzu or Bjorn, Cavalry behind Pelagius or Genghis Khan, and mixed troops when the primary commander specifically rewards them.

Should I expertise Osman I?

Yes, eventually. Expertise raises The Empire Awakens from 850 to 1,100 damage factor. Because Osman is Epic, 5-5-5-5 is realistic without sacrificing valuable Legendary sculptures.

What formation is best for Osman I?

Wedge is a practical choice when Osman leads a Skill Damage-focused march. If he is secondary, choose the formation based on the primary commander instead.

Conclusion

Osman I remains a practical early-game commander because he delivers straightforward Skill Damage without demanding expensive Legendary investment.

The Empire Awakens reaches 850 damage factor before expertise, Sword of Osman adds another 400 follow-up damage factor, and Sultan’s Glory provides 10% additional troop capacity.

Once expertised, Rising Empire increases Osman’s active damage to 1,100, giving him a simple but effective early burst combination.

For open field, build around Skill and Leadership talents with Rage generation as the main priority. If another commander has better Infantry, Cavalry, Archer, or mixed-troop talents, move Osman into the secondary position and let his skills provide the damage.

There is also no reason to overcomplicate his skill progression. Max the first skill before unlocking the others, then let regular Epic sculptures carry Osman naturally toward 5-5-5-5.

Use him aggressively during early kingdom development, avoid unnecessary focus fire, and gradually replace him as stronger Legendary marches become available.
