This is Wraith.
He uses an experimental beam katana for melee encounters.
And currently uses a fully-modded sniper rifle as his main weapon.
He uses experimental Chinese stealth gear. His suit is more advanced than the model of stealth suit that was used in the battle for Anchorage, but it's also less stable, as is all of his gear. He's susceptible to the same effects Nightkin develop from prolonged Stealth Boy use, and the suit's incomplete circuitry requires frequent recharging or replacement of power cells. He's good with tech, so he can modify energy weapon ammunition to keep the suit working.
The instability of his suit, along with the Stealth Boy effect, exposure to the internal parts of energy weapon ammo, and extreme radiation encountered in his line of work have led him to develop a unique type of ghoulification. He's somewhere between a Nightkin and a Glowing One. Because of his appearance, he only removes his suit when he's alone. He uses Med-X to deal with the physical and mental anguish of his condition.
To enhance my immersion with this character, I acquire and throw away 15 units of any energy weapon ammo per day, pretending it's for the suit. In order to keep him stealthy, I have to find a container or hidden location to dump the ammo in, so he isn't leaving a trail someone could follow. If I ever run out, I use the non-stealth version of the armor. It's a little too easy too find the ammo I need, so I might have to increase the ammo used. I also use a lot of Med-X, to lessen the symptoms of his unique ghoulification, and have gotten him addicted. He uses about ten doses per day. It's quite the balancing act, trying to keep him swimming in ammo and Med-X, but still save caps for the Bozar.
