The slavers from the jungles of Chult often rely on underhanded techniques to keep their slaves in line. When a particularly difficult slave is caught attempting to escape, he will sometimes be kept in line by poisoning him, just enough to make him sick. The slavers then show the slave the antidote and force his cooperation. Most of these slavers allow their guards to carry weapons coated in the vile substance, for quick punishment or weakening an attacker.
