I’m sorry could you tell me what an ESP hack is?

What I’m envisioning is an invisible flying sensor like an eye. Sort of like when people do that trick on admin to fly and no enemies react to them. You open the map click on a point and your sensor appears there. Then for a period of time you can fly about invisibly. You can’t go through walls or closed doors so you can’t use it to scope out someone else’s base in PvP. Of course to use the scrying table you must use either sacrificial blood or soul energy. Personally I think it should be soul energy to give that resource another use. Maybe even allow the sorcerer to pick how many soul orbs to use to extend the duration.
