The Withering revolver is a very powerful weapon only to be used by the most skilled marksmen and not by any just unkown and stupid person. If used by someone that is not qualified they will wither there body until there is nothing left.

It’s up to you to decide whether a character has proficiency with a firearm. Characters in most D&D worlds wouldn’t have such proficiency. During their downtime, characters can use the training rules in the Player’s Handbook to acquire proficiency, assuming that they have enough ammunition to keep the weapons working while mastering their use.
