Even before the development of its counterpart, Hattokinetics, the T’zun scientist Neysa Kurare discovered the physical principle of Neysanics. It forms the basis for energetic protective shields to intercept hattokinetic projectiles and energy in general.
Neysanics works with general energy that is effective against all hattokinetic energies. In principle, a hit causes an increase in the amount of energy within the shield. The thrust is deflected and dissipated over the ground if the material of the ground allows it. If not, the excess energy is diverted into the shield generator or the systems of a combat suit. If this happens, too many hits in a short time can lead to an overcharge that temporarily turns off the shield so one is not cooked. The whole thing is an outdated technology.
