Amon started training to use his 'conceal' ability; he thought it would be easy for him to learn it, but the reality was often disappointing.
He had never imagined that it would take him many hours of hard work to succeed even once.
This was very different than when he learned the other four types; he could learn them by instinct.
However, to learn it, he had to put in so much effort.
To use concealment, he had to gather all the Prana inside his body to a particular place and stop it from moving or leaking out.
This required intense concentration, and after thinking about it for some time, he chose the heart as the place.
This also gave him the advantage that he could perform enhancements very quickly.
The problem was not learning this skill; if he remained stationary, he could easily use it.
