Nurse

The Nurse is an NPC that will spawn once the following criteria have been met:
 * There is an empty house.
 * The player's maximum health is greater than 100.
 * The Merchant is present.

The Nurse will heal the player's health and cure them of any active debuffs at the cost of Coins (there are exceptions, see Notes and History).

In the versions, healing costs can range from a few Copper to several Silver Coins, depending on how much health the player is missing. She charges Copper equal to 75% of the health restored (e.g. for restoring 100 health), plus an additional  for every active debuff on the player.

In the, healing costs are equal to 100% of the health restored, plus an additional per active debuff on the player, all multiplied by the Nurse's current Happiness price adjustment, and then doubled if playing on. Also, the Nurse charges increasing amounts of money for healing as the game progresses; these specific increases are detailed below. Thus, at the start of the game, the cost of restoring 100 health can range from /  (with maximum happiness) to  /  (with maximum unhappiness), while by endgame it can range from  /  up to  /.

In the, she will fight enemies by throwing poison syringes that will deal 8 /  /  damage (plus, on , various stat boosts) and poison enemies for 3–5 seconds. She can also use healing syringes to heal herself and other friendly NPCs for 20 health.

Price Increases
The cost of healing changes based on three factors: The Nurse's current Happiness, game progression, and. Happiness affects the Nurse's price by raising or lowering it to within a range of 75% to 150% of its base (in the same way that other NPCs' prices are affected by their happiness). Playing in Expert (or ) mode further affects prices by permanently doubling them. Progression-based price increases are based on which bosses have been defeated in the current world. These increases are listed in the table below; only the single highest applicable increase is chosen and applied.

Tips

 * The Nurse can be used as a "healing station" when at low health during a boss fight, by teleporting to the spawn point (using a Magic/Ice Mirror) where the Nurse is present. Autopause can be used to grant more time.
 * On the this trick is harder to use then on the, as Autopause does not pause enemies or events while the nurse's menu is open.
 * The Frequent Flyer achievement can be a difficult achievement to obtain (with the exception of desktop versions), as it is very cheap to get healed by the nurse, unless you have a debuff. Having a nearby trap that inflicts a debuff, such as lava or a dart trap, can help a player obtain this achievement very quickly.

Trivia

 * There appears to be conflict between the Nurse and the Mechanic during a Blood Moon. During this time, the Merchant has a chance of saying, ""
 * The Arms Dealer seemingly has romantic interest in her according to his quotes when the Nurse is present. This is also reflected in the Nurse's quote "" The Nurse, despite her apparent feelings for the Arms Dealer, is already in a romantic relationship with someone as noted by the Stylist in her quote, "Mhmm, I heard from &lt;name of Party Girl&gt; that &lt;name of Mechanic&gt;'s friend &lt;name of Nurse&gt; spent her boyfriend's last paycheck on shoes." However, this could most likely be the arms dealer.
 * The Nurse is depicted in a painting called "Nurse Lisa", a reference to the famous portrait painting  by the Italian Renaissance artist.
 * When talking to the Nurse while in a crowded area, she will say, "Hey, I dislike the lack of social distancing here." This is a reference to the 2019-2020 Covid-19 coronavirus outbreak that was ongoing at the time of Journey's End launch, and the "" practice people were encouraged to follow by staying six feet or two meters away from people in public.
 * During a, when the Nurse dons a party hat, her hairstyle is different. She wears it down instead of up in a ponytail: Nurse (Party).png This makes sense as wearing a party hat while having hair in a ponytail would be cumbersome.
 * The Nurse will not say "" if the Blood and Gore setting is turned off.
 * The Nurse will not say "" if the Blood and Gore setting is turned off.


 * Although the Zoologist is registered as hated by the Nurse, she doesn't seem to actually hate her. The dialogue indicates that the Nurse hates the Zoologist's unique anatomy more than the Zoologist herself: "I hate treating  the Zoologist, so difficult!"
