"True. Normally, you could easily enhance the body strength through mana. But, there are a few flaws to this technique. Did you know what it is?" asked Balrug as he tested Angus.

"Hmm… the enhancement will be reverted back after not being supplied with enough mana." Replied Angus immediately as he also realized this kind problem from the start.

Although mana is different, it is similar to chi and every person has a limited amount of it. Once they empty their mana pool, they will turn into slightly stronger than ordinary ungraded people.
