Holoparasite
Holoparasite is a ghostrole, and a beast of a familiar, at the service of any Traitor at the cost of 14 TC from their uplink. They are incorporeal, unable to be hit by projectiles, and move at a much faster speed and do heavy amounts of brute damage, and are able to move even when their summoner is stunned, restrained, or crit.
However, they share damage with their summoner, and will disappear permanently upon death.
Holoparasites come in all sorts of shapes and colours, but will always be instantly recognizable.
Fundamentals
When a holoparasite injector is used, a ghost role will open. Once you spawn as a holoparasite, your summoner will be notified with a silent message only visible to them, "Your guardian now has a soul."
From here, make sure to stay quiet! Only talk in a whisper, and only if you are 100% certain you are alone. Being heard or seen is a surefire way to get a KoS(kill-on-sight) order on your summoner.
Make sure to encourage or remind your summoner to clean and dispose of their holoparasite injector as well as the box it came in.
You may receive some retaliation when mowing down your victims. Make sure to keep in mind that any melee damage can affect you, and your summoner as well.
Your summoner can choose when to summon and un-summon you with an action. Don't move too far away! You're a tool for close quarters combat. If you or your summoner move too far away from each other, you will instantly be un-summoned and put back inside them.
