Nurse

The Nurse is an NPC that will spawn once the following criteria have been met:

The Nurse will heal the player's health and cure them of any active debuffs (there are exceptions, see Notes and History), for a price. 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, Additionally in master mode the cost is changed to 75% of the players health in silver (e.g. 75 for restoring 100 health)

In the, the Nurse charges increasing amounts of money for healing as the game progresses.

In the, she will fight enemies by throwing poison syringes that will damage and poison enemies for 3-5 seconds. She can also use healing syringes to heal herself and other friendly NPCs for 20 health.

The Nurse prefers to live in The Hallow, with the Wizard and with the Arms Dealer. The Nurse dislikes the Dryad and the Party Girl and hates the Zoologist.

When living in a densely populated area:

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.
 * 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 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 "social distancing" practice people were encouraged to follow by staying six feet 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.
 * A 'happy ending' is a reference to the real-life practice of masseuses offering sexual favors (happy endings) to their clients at the end of a massage for extra money
 * Although the Zoologist is registered as hated by her, the nurse doesn't think she is bad or anything. She tells this in the line "I hate treating  the Zoologist, so difficult!"
