In the third level of the sewer, Abel, Black Wind, and the spirit guardian knights roamed around like nothing was in their way. Their increase in power had boosted their attacks and defense to a whole new level. Under the fire enchantment and the 'extra damage' of the spirit guardian knight captain, this team of spirit guardian knights was basically invincible.
The spirit guardian knight Naga's poison attacks were wiping out fields of hell creatures. On the other hand, the Oak Sage was duly standing beside Abel, giving all his summons extra life.
By this point, he had regained that demolishing thrill he got when he was in the Rogue Encampment. His team of spirit guardian knights' fighting power had become far superior to human head commanders. Since they were riding spirit wolves, their flashing ability would basically be a nightmare to intermediate wizards.
