Sunlight Power was similar to Dragon Power.
It was practically equal to Dragon Power in terms of fast recovery. This ensured a soldier's endurance in battle. It could also heal. Though it wasn't as crazy as demonic power, it could still lower the casualty rate.
There was also a unique attribute. Under the sun, a Sunlight Warrior's attributes would increase. If they were under the sun when close to dying and had strong enough willpower, they could recover just by sunbathing.
Link had a deep knowledge of each type of Warrior's combat ability. He estimated that his Sunlight Warriors could completely counter a demon of the same level. This way, Ferde possessed a Sunlight Army of 30,000 that could fight demons face to face.
This huge force could change the entire state of the continent.
