A '''Doctor''' is a role that targets a player at Night to protect that player from a single kill made during that Night.  They are not told if their protection was successful.  Protection from a single kill means that if multiple players try to kill someone, they will not be saved by one Doctor's protection.

In a [[Werewolf]] game, the Doctor is frequently referred to as the [[Archangel]] (blocks mafia kills) or [[Sorceror]] (blocks werewolf kills). 

==Variations==
Most moderators '''do not allow the Doctor to self-target'''.

In order to prevent Doctors from protecting the same player constantly, some moderators do not allow Doctors to protect the same player on consecutive Nights.

Some moderators cause Doctors' protection to stop ''all'' kills that would resolve on the target that Night.

While this is highly frowned upon at mafiascum.net, some moderators will tell players that they were saved from death via a form of protection (i.e. Doctors).  Some moderators will even announce who was saved from death publicly at the beginning of the next [[Day]].

In games with kills made during the Day, Day-Doctors have been known to exist.  However, Doctors who protect at Night may or may not be able to protect against daykills.

In games with [[poison]], it is up to the moderator as to whether Doctors protect against the poison.  If not, occasionally specialized Poison Doctors will be introduced.

==Sanities==
:''see also: [[Faith Healer]]''

There are five variations of the Doctor role, typically called ''sanities'' analogously to the [[Cop]] sanities.

*'''Insane Doctor''': This doctor has 50% chance of killing his patient instead of protecting him.
*'''Paranoid Doctor''': This doctor not only protects his patient but he also roleblocks him. See also: [[Jailkeeper]].
*'''Naïve Doctor''' (a.k.a. [[Quack]]): This doctor's protection is ineffective.
*'''Weak Doctor''': This doctor dies if he protects an [[anti-town]] player.
*'''CPR Doctor''' (also a [[Quack]] variant): If the patient is NOT saved from death that Night, this doctor kills its patient.

When a [[Game Moderator]] uses these roles as sanities, the player receiving the role is usually only told his/her role is Doctor. Sometimes sanity is revealed upon death, but frequently not, leading to ambiguity if a Doctor is killed early in the game.

These "sanities" are very rarely used as such.  However, [[CPR Doctor]] and [[Weak Doctor]] have gone on to become viable roles in their own right, and players are generally told that their full role names.

==Use and Power==
Doctors exist to deter the Mafia from making "obvious" kills.  They can be used as a standalone power role dedicated to stopping obvious Townies from dying, or they can be intended to stop power roles from dying after they claim. 

In practice, the latter purpose is far more effective.  Doctors are notoriously bad at protecting against Mafia kills when there is no obvious target; they are weak on their own.  However, if a power role claims, the Doctor has no reason not to protect that power role.  This prevents the Mafia from killing the power role, and that role can go on to safely and publicly aid the Town as well as it can.  Thus, Doctors make the game much more focused on power roles and Night actions.

It is '''very important''' when including a Doctor in a game to check for broken combinations arising from its synergy with other power roles.  [[Follow the Cop]], for instance, arises when it is known in advance that there is a Cop and a Doctor in the game.  Another broken combination involves two Doctors in the same setup; they can protect each other each Night and thus become immune to kills for the rest of the game.  Because of this, full Doctors have fallen out of vogue in favor of [[Jailer|Jailers]] or simply not including a protective role at all.

It is not unheard of for Mafia to have Doctors of their own in games with Vigilantes or Serial Killers.  Their power is about the same in practice as that of standalone Town Doctors.
