The Ronin is a unit of the Serpent Clan.
In every age and nation, there are wise men of heroic strength: those whose swords shine in the nightmares of a hundred widows, and whose martial arts skills are no longer quite human. So it was with the samurai of the Dragon, and so it is with the Serpent Ronin: dark mirrors of their ancient counterparts, rejecting the samurai's code of honor as weakness, yet honing their talents to just as keen an edge. Such men make deadly foes, on or off the field of battle.
In combat, Ronin wield a pair of razor-edged katanas, reasoning that their unholy proficiency with two blades will strike fear into those who cannot brandish one with equal force. In order to master this complex fighting style, they train only with blades, disdaining the Samurai's bow. When one of these hardened veterans perishes in battle, his accumulated ferocity and bitterness curses the very place of his death, while spurring his allies on to vengeance.
They can also call the four strong-willed Serpent Ronins to sacrifice their lives for the Necromancer to be delivered onto the mortal realm and commence the slaughter.
The Ronin is a powerful Tier-3 unit that deals great damage with his twin katanas. When a Ronin dies, he stabs the ground with his swords, creating a small magical field that slows enemies, while increasing damage of his allies, although the swords are destructible.
The Ronins Battle Gears are: Yin Blade can be used to drain the stamina, adding the number of Yin points and even change Ronin's damage to magic while Blood Bond can make another unit take the most part of the damage incoming to Ronin. 
Drains Stamina and requires 10% of total stamina
|Requirements: Metal Shop||Requirements: Thieves' Guild|
|Damage from magical blades drains enemy stamina to create Yin; continually drains user's stamina.||The Thieves' Guild is not considered a scholarly group, but they do have access to certain volumes of dark sorceries. Using these, a strong-willed Ronin may enslave another's soul to his own. Such a Ronin finds himself invulnerable to harm, as his wounds are magically transferred to his helpless slave's flesh.|
- Ronin (Japanese: 浪人 Rōnin) literally means drifter or wanderer.
They are mostly Samurais who were without their masters or fell from grace, earning the name "Ronin", usually becomes mercenaries.
- Ronin's fighting style bears similarities to Niten Ichi-ryū, a style developed by Miyamoto Musashi that would use two long swords or a long sword and short sword, usually the wakizashi. Musashi himself is a Ronin.
- Yin Blade battle gear changes Ronin's damage from 25 (cutting) to 20 (magic).
- Both Ronin and Samurai have the exactly same weaknesses, resistances and hitpoints. But Ronin may acquire "Reinforced Plating" upgrade which raises his piercing/blunt resistance where as Samurai may acquire "Dragon Fire" upgrade, which raises his hitpoints.
- Ronin use only one sword while on horseback.
- Same as Samurai, Ronin can't use "Cursed Swords" while mounted.
- When the Ronin is the last unit killed before his clan falls, Cursed Swords boosts enemies' attack damage.
- According to the original manual, the Ronin's Yin Blade was supposed to heal the Ronin by "suck[ing] ... life force" from the enemy attacked. This is evidenced by the Battle Realms data editor, where there is an option in the weapons tab showing a row for "HealthVampirePercentage (Float)".
- In the manual, Cursed Swords would boost allies' attack damage and reduce enemies'. Upon release, Cursed Swords slow enemies instead.

- ↑ After Reinforced Plating is researched
- ↑ After Reinforced Plating is researched
- ↑ It's impossible to certainly say that Blood Bond Battle Gear is intentionally planned to be like that, but the target, that is bonded with Ronin takes 75% of the damage, incoming to Ronin, while Ronin still receives 50% of the damage. Thus it's 125% of damage in total. It's probably an overlooked issue. Blood Bond proves to be useless in serious multiplayer BR games, and is quite useless offline.
- ↑ A note from Battle Pack 3 reads: Changed the Ronin Blood Bond damage distribution - 50% to bonder, 100% to bondee.
