|"The Shadow calls."|
In the time before the breaking, ninjas were thought to be monsters from bedtime stories, black-clad men who lurked in the shadows, killing silently by blade or poison. And now, we know that they are real, fighting a war against the monks and occasionally taking a hand in the bloody clan wars.
Little is known of their motives - they seek only to serve the dark principles of the yin.
Drains Stamina when walking/running
|The ninja uses shadows and tricks of the mind to seemingly disappear into thin air, reappearing when their opponents' guard is down. Anyone but a monk would surely be fooled.|
- Ninja units grow more powerful in accordance with how many Yin points the player currently has. If the player has no Yin points, the ninjas will remain at average strength. However, if the player has the maximum amount of Yin points the ninjas will become significantly stronger.
- In the "Kenji's Journey" campaign of the original Battle Realms, it is possible to recruit either ninjas or monks, regardless of which clan Kenji belongs to.
- Normally, any units but Monks will not engage a stealthed Ninja, except when given order.
- Enemy wolves easily detect hidden Ninjas.
