Countless eels started to jump out of the swamp by releasing torrents of poisonous water, but nothing managed to reach Noah. Such weak specimens couldn't get past his rain of slashes, and even those in the middle tier died when they faced precise attacks.
The eels weren't strong individually. They were magical beasts with low requirements in terms of energy, which allowed them to grow immense packs. Their power came from the poisonous waters that they released, and Noah eventually began to suffer because of them.
A single attack couldn't go past Noah's fiendish armor. Even hundreds of them couldn't break through his defenses, especially since nothing ever got too close to his position. However, the fumes intensified as the battle continued, and the modifications made to the dark world slowly became ineffective.
