Doctor

Healing your target
You can heal all attacks on your target caused by, , the , , a role, , , or the. You cannot heal:
 * You can heal a who died protecting someone. This does not allow them to kill a possible second attacker during the same night.
 * If you heal someone who is visited by a, you will die but your target will remain alive.
 * Healing someone gives them temporary Basic defense.
 * Anyone executed by the, doused or ignited by an , or haunted by a.
 * Any suicide methods (A killing themselves from guilt or someone who has left the game).
 * The once they reveal themselves.

Notifications
You will be notified if your target was attacked, including a 's bite.
 * You will receive only one notification, no matter how many times your target was attacked.
 * Your target will receive a message about being healed. They will not receive additional messages if they were healed by multiple Doctors.
 * You will still receive the message that your target was attacked even if they were protected by a or have Night Immunity.
 * You can heal an, , and a who role blocked the  or  (On Full Moon nights). However, you will not see that your target was attacked.
 * If someone is successfully healed, their attacker will not get a message of any kind.
 * However, if their target had Night Immunity, the attacker will still get the message saying they are immune.

Strategy

 * Lay low, and avoid revealing your role unless completely necessary. You can use your ability to secretly protect someone from death, while staying under the 's radar. Don't say anything if you healed someone the previous night, or if they say something along the lines of, "Thanks Doc!" Even whispering to your target, while it might be tempting, can be dangerous, since the is usually smart enough to kill whoever whispered to someone who is being killed; generally, you should only whisper to your target if you believe they are a Doctor or  and are trying to pair up with them.
 * Keep your self-heal for later in the game. There is little chance of the attacking you early in the game, especially if you haven't revealed your role. However, as the game goes on, it gradually becomes more necessary to reveal your role. If you have to reveal your role, it is recommended to use your self-heal that night, as the Doctor is a nuisance to the, as well as the.
 * The most important basic strategy for a Doctor is to identify confirmed  so you can heal them. As an added bonus, anyone who can be publicly identified as a is more likely to be targeted by the . When you lack other ideas, people to heal include:
 * Anyone who has voted a member of the up to the stand, or who provided decisive evidence to hang a member of the.
 * Anyone who has been confirmed via their abilities, such as who put their name in their Death Note, or anyone brought back to life by a . (Note: This strategy will not be viable in the next patch due to all Death Notes being removed from  roles.)
 * If someone passes a -test, do not blindly heal them as they may be a . Only heal them when said "" is confirmed by role filtering or by a confirming that they are a genuine.
 * Healing a allows them to jail any target without fear of the target being the  or . (However, if the  attacks the  directly, you will be attacked as well).
 * Two Doctors healing each other are very difficult to kill. Only either a (redirecting one Doctor's heal elsewhere), an  or a  (stopping one Doctor from healing the other), an  (burning both without being able to heal each other), a  haunt or lynching can pass through their defense.
 * If your target was healed, and someone was killed by a the next morning, but no  died, then you almost certainly healed the . Most of the time, you should immediately whisper to them, claim to be a Doctor, explain what happened, and ask them to cover you for the rest of the game while you heal them. This creates an almost unstoppable team.
 * Healing a allows them to kill anyone who attacks their target, without them dying, until you are killed. This also allows you to indirectly provide indefinite protection to a, who you cannot heal directly, as long as you yourself are not attacked.
 * A Doctor/ pair that are constantly healing/protecting each other is almost impossible to destroy. This is similar to a Doctor/Doctor pair, with the difference that the can kill whoever tries to stop the Doctor. A killer will have a 50-50 chance of either failing to kill or being killed themselves. As long as the Doctor is healing the, the  will recover from every successful defense.
 * A will die if he tries to kill any of the pair. If he targets the Doctor, he will get killed by the . If the  instead targets the, the Doctor will be attacked due to him visiting the , triggering the 's protection, thus killing the  and leaving the combination intact.
 * If a jails either the Doctor or, the person not jailed will likely be exposed to any attacks. If you self-heal, you can still survive the night unless you were doused and set on fire on the same night or you were role blocked and killed.
 * A, , or can also break this defense by redirecting or role blocking one of the pair.
 * can usually confirm by posting a record of who they transported, but healing them after they're confirmed doesn't make as much sense as other confirmed, since they'll usually be using their ability to protect themselves afterwards.
 * A common misconception of a good strategy is waiting before you heal anyone right away (on the first night). The argument goes that you could accidentally save an evil role or run into an unexpected . However, this looks very suspicious and you miss the opportunity to get a to confirm you (if they visited the same person), as well as the fact you are more likely to heal a.
 * You will know if your target is attacked. This can indicate their innocence in a number of ways:
 * If there was no attacks from the that night, it means your target may have been attacked by the ; aside from rare shenanigans of a  or, that would mean they're not a member of the , since the  can't normally attack themselves.
 * If the attack looks like it was from the or a, it can indicate that your target wasn't that role (but, of course, they could still be part of the .) It can be hard to figure out if you've saved your target from becoming a , but that's also another potential cause for the message. (and the messages are indistinguishable.)
 * If you seem to have healed your target from a 's attack, yet survived yourself, this means that they weren't the 's primary target; in other words, it means they're a visiting role and visited the 's target. If the 's target died to the or  in this situation, and no member of the  or  came up dead, then it's extremely likely you've actually saved an evil role!
 * Of course, if you save the 's primary target, you will die, but the person you healed will survive.
 * If you know who the is (for example, if a  goes on alert Night 1 and someone who died from the  was able to record it in their Last Will) it's a good idea to team up with them. You can tell them you're a Doctor and that you'll heal them until you die, while in the meantime the  saves their alerts for later in the game.
 * If there aren't any confirmed (most commonly in early game), it might be useful to heal the most talkative players. These players are typically targeted by the, as they usually are an important role that is trying to figure out who the  are.
 * If someone you were healing dies anyway (and the cause is something you could have healed, not suicide or an ), it means one of two things has happened:
 * First, your target may have been transported. This means that your heal was redirected on to someone else, and the attack was redirected onto your target. Note that this means that your target wasn't the one who the attacker intended to kill. You can try to confirm this by asking if anyone was transported; if anyone speaks up, they were probably the real target of the attack.
 * And second, if you selected/changed your target just as the night ended, it may not have reached the server in time. This is especially true for low end computers.
 * You could also have been controlled by a and redirected onto another target, but it would be fairly obvious as you would have gotten a message. There is a very rare bug that the control message does not show up, though.
 * If you're being controlled by a every night, take note if your target is healed (and write what night it happened in your Last Will). After the first night, a  is probably making you target them, so you may be able to identify them if they're later called out by an attacker as having a defense higher than said killer's attack value.
 * If you are aware of a  in-game, be careful when stating you are the Doctor, as doing so gives the basic protection every night. Under no circumstances should you reveal that you are the Doctor unless you ask a  to transport you or a  to watch you in order to bust the.
