Boss Battle?

It was difficult for Eliza at first as she had actually never had to absorb energy from magic stones, but it was a process she had seen quite a lot when she was at home so she was able to get the hang of it relatively quickly.

After a few dozen magic stones were absorbed, Eliza found that she seemed to have hit some sort of barrier and could not absorb any more, so Evan got her to level up some more, and in the process, the barrier broke and her level shot up by two instantly.

She then spent the next few hours writhing in pain due to the fact that her body was in the process of strengthening itself and she couldn't heal herself since her magic power was going haywire and even the most basic healing spell couldn't even be constructed.
