Air Bombs!

It had recovered enough to be back at level 2.5 now, however; it was still showing an Injured Soul status, certainly meaning he could go beyond his previous level once it was perfectly healed.

Soul Level was closely linked to the soul power he had. If he increased his stats and skills too high, he might have issues with fueling his newly acquired abilities.

Two things could happen. He could empty his reserves of soul power too fast, and reach a feelless state faster than normal. If his physical stats were also too high for his current body to support, it might injure him as his Gift Fury had done in the past.

The only reason his body hadn't crumbled despite most of his stats having gone past those of Challengers was that his soul, even injured, has already reached an Ascender's level.

Taking into account the stat caps of 3 for challengers, he could guess more or less than going beyond 6 for an Ascender was probably suicide.
