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 (there are exceptions, see Notes and History), for a price. Healing costs can range from a few Copper to a 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, 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. If the autopause option is off and the player is talking to her, she won't heal herself, resulting in her death if she keeps taking damage. Keep this in mind if you are going to use the nurse in a boss fight.

Tips

 * The Nurse can be used as a "healing station" when at low health, e.g. 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.

Trivia

 * There appears to be conflict between the Nurse and the Mechanic during a Blood Moon. When both are present, they have various hostile sayings that replace their standard quotes (see Quotes). 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.
 * 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 never says "" if the Blood and Gore setting is turned off.
