Yuan-ti Broodguard

Yuan-ti Broodguard
Yuan-ti malisons who become priestly devotees of a particular god-be it Sseth, Dendar the Night Serpent, or Merrshaulk-often rise through the ranks to become spiritual leaders among the serpent folk. These priests perform sacrificial rites to appease their vile gods.
Yuan-ti Broodguard
Broodguards are humanoids transformed by yuan-ti into simple-minded, scaly creatures that do their masters' bidding. The transformation process warps not only a subject's body but also its mind, making it instinctively obey any yuan-ti and filling it with a seething rage that rises at the sight of non-reptilian creatures.
Although broodguards have low intelligence, they are able to perform simple yet important tasks in the community, such as guarding eggs or patrolling for intruders. The yuan-ti refer to broodguards as 'histachii,' which means 'egg-watchers.'
Human No More
Most broodguards are made from human prisoners forced to consume a magical brew that renders them helpless and unable to fight off the inevitable. A human transformed into a broodguard loses all semblance of who it once was, and even its human origin is barely discernible. A broodguard is hairless and emaciated, with yellow-green, scaly skin. It has beady, bloodshot eyes and a forked tongue, and smells faintly of rotting meat. Broodguards can speak but rarely do so, preferring to use snake-like hisses and guttural noises.
Making a Broodguard
Yuan-ti create broodguards from captured humanoids. Each subject is fed a special potion that immediately renders it incapacitated and transforms it into a broodguard over the next 1d6 + 6 days. A subject forced to imbibe the brew can make a 15 Constitution saving throw; on a success, it takes 14 (4d6) poison damage and isn't otherwise affected.
A spell such as lesser restoration or remove curse can end the transformation process at any time before it runs its course. After the process is complete, only a wish spell can reverse the effect.
