Siren's equipment

Lux: Her revolver, a decorated weapon that has the appearance of a common Human firearm. In reality, it is a very advanced piece of technology. Rather than holding bullets, it contains a hard light generated that fuses light into solid projectiles and fires them at high velocities. It has three settings: stun, scattershot, and precision shot. Stunning rounds are softer and fiction like rubber bullets. Scattershot rounds function like shotgun rounds, shooting many small pellets in a spread. Precision shots are simple hard light bullets, nothing too special. Vortex Manipulator: it's..well, if you're a Whovian, you'll know.

Just like in Firefly XDD Approved

On one arm is a heavy gauntlet that's a coppery/brass-ish color. It has a vortex manipulator built into it. It also has a component within that generates a surge of plasma, which is contained by a small, weak forcefield. Humans would refer to it as a plasma sword or energy blade, or whatever the popular sci-if genre dictates. Anyways, this component creates a foot long blade of plasma from the top of the gauntlet forearm
