People can sense the Cursed Energy around them, given it’s not concealed, based on their CTRL. While it cannot substitute for vision, nor pinpoint the exact location of the cursed energy, it allows them to identify that something is there, and generally tell how much cursed energy the entity has.
Energy sensing range is the user's CTRL x 2. ( 60 CTRL means the user can sense within a 120M Radius of themselves. )
Comes innately with everyone and does not need to be purchased.
Bought off the store for 5 JP, Energy Concealing allows the user to conceal their cursed energy signature. This makes them undetectable through the aforementioned energy sensing. This does not remove their physical presence, such as sound, smell, sight etc.
Concealing is flawed, even then. Someone can sense through your concealment given their CTRL beats your CTRL.
While concealed, your CURSED ENERGY output is limited. You can only expend Cursed Energy from your pool equal to your CTRL stat per turn.
E.g if you have 20 CTRL, you can expend 20 Cursed Energy per turn while concealed.
