Exploiting almost sounds like you are talking about something on computer or such, or exploiting a game, but in this sense it is technically the same. Exploiting the programming and functions of a construct that isn’t yours to override it, break it, edit it, etc.

Exploiting in of itself is a Art that you learn as you go in, you learn the common exploits in a construct, and such.
Normally you learn one through examining the blueprint of a construct or the programming of a made one already. (When it’s someone’s shield, etc).

Common exploits can be found inside the functions of a shield, such as how well it defends from attacks and such One of the common exploits is simply through “projecting” inside of the shield as most do not actually realize that is possible, or making a focal point on the other side. Another is “Hiding” your energy as the persons.
