Plasma Weapon

Plasma is the fourth state of matter. Though it can be used as a power source, plasma is best known for its use as a superheated thermal weapon.

Overview
Plasma weapons require both a gas reservoir and a battery to operate. The reservoir, often a magazine-like device or backpack, contains gas, also referred to as the 'fuel.' The battery provides power to the weapon's electrical components and allows it to energize the gas into a plasma state; the plasma is then propelled out of the weapon in a super-heated state via electromagnetic energy. Both the battery pack and the reservoir need to be periodically replaced or refueled. In some cases, the reservoir and the battery are one in the same, though in other cases, they are two distinct devices.

Plasma is devastatingly powerful thanks to its intense thermal energy; upon contact with flesh, the plasma will vaporize the impact site, burning away skin and bones while causing blood and other bodily fluids to evaporate while cauterizing the wound in the process. These wounds are oftentimes fatal unless immediate medical aid can be administered. Armor provides only limited protection, as plasma will simply burn through the armor with each subsequent hit. Plasma projectiles can 'splash' upon hitting a target, posing a significant risk to anyone nearby and potentially sparking fires. Plasma can also makes for an effective psychological weapon thanks to its bright colors, visible projectile, and its reputation for horrific burns.
