Cortical borers: a worm like parasite that has the chance to spawn as a nutrual antagonist as a random event
concept: Cortacal borers replicate by infecting host's brain by crawling through their ear, and controlling their mind to produce more of their kin.
field gameplay: Cortical borers infect the host's brain (other humanoid players) by quickly crawling into it's ear, this is achieved by at least two seconds of time before it has successfully entered the host's brain, to which the host is alerted by a message saying "you feel pressure behind your ears." to which the borer is able to gain control of it's host after being on it for at least three minutes. the borer is also capable of injecting chemicals into the host's bloodstream, however, harmful regiments are forbidden. replication of it's kin is a process that begins immediately after infecting the host, to which the new borer will take around a minute to produce, and be ejected via vomiting through the host's mouth. after the borer has been inside the host for 10 minutes, it will be able to create regiments capable of possibly stunning or muting the host, as well as crocin (for all you special advantage takers out there).

"you are being controlled!" sprite
THE IDEAS FOR THIS ARE NOT TOO FAR OFF FROM THE ORIGINAL, TWEAKS TO THE IDEAS WILL BE MADE, VOICE YOUR OPINIONS!!!




yes, these sprites are my own.
(EDIT)
the borer would only be able to spawn via syndicates or xenobio
syndicate borers have ability to kill its hosts if nessisary, and has access to harmful regiments, and can overdose its host if it so desires
xenobio spawn borers are prevented from overdosing, have no harmful regiments, and are restricted from killing or harming hosts (and maybe they're not allowed to replicate either)
