Training.

With that out of the way, Ark only needed to try out his poison magic, summoning magic, as well as the suppressive effect of his [Chaos Domain] on enemies. Since he was beginning to run low on mana after his experiments with time magic, Ark decided to test them another day. Although he could still try it out and have mana left afterwards, Ark didn't feel comfortable walking around with his mana pool depleted, no matter how quickly it recovered. He had experienced too much agony because of his insufficient strength. Now that he was finally starting to become truly strong, he wouldn't make such stupid mistakes.
