Step towards Next Rank
"What's the limit?" Asher asked, looking at the skill.
"Will it work on anything?" He queried.
Although the skill itself was good, as it allowed Asher to hide his true Rank up to two major ranks, it was a well-known fact that concealing your mana did not work on hunters of a higher rank than you.
This meant that Asher could hide his mana core rank from Damian, but he would fail in front of anyone who was C Rank and above.
The techniques that Asher knew about concealing his presence became useless if he was not using them every time he met someone higher rank than him. It was simply not feasible to do, as he could not conceal his presence at all times to hide his true rank.
Even in that case, such techniques stopped working on S Rank Hunters and higher because their mana sensitivity was way higher.
However, this skill would work even if Asher was standing in front of an SSS Rank Hunter like Nathan Greville.
