Viking continued to battle GraphicZ. He had drunk another recovery potion when he was towed by John's water tentacles, so he could still cope with another battle.
John faced Gridhacker. In theory, his class should be at a disadvantage since none of his summons aided his battle, but the bloodline gave him superb underwater movement. He was also more experienced than Gridhacker at underwater battles since he spent much time underwater hunting for aquatic monsters' essences. Gridhacker's spells had a hard time hitting him. With perfect timing, his standard attacks and basic spells instead caused Gridhacker troubles.
Additionally, John could use mana manipulation while Gridhacker couldn't. Even his standard attacks packed a punch. He could control the flight paths of his Repeating Mana Bullet and Energy Bolts. This gave him an additional edge.
