Dryad

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


 * There is an empty house.
 * The Eye of Cthulhu, Eater of Worlds, Brain of Cthulhu, Skeletron or Lepus has been defeated.

In addition to selling items, the Dryad can also report the percentages of Corruption/Crimson and Hallow that exist in the current world.

On the, when enemies are nearby, the Dryad will periodically grant the Dryad's Blessing buff to players and other town NPCs in the vicinity and displays a leaf barrier effect. The buff grants +8 defense to players and +6 / /  defense to town NPCs, increased health regeneration, and gives the player (and town NPCs) a Thorns effect. Enemies within the leaf barrier and with clear sight to the Dryad will be inflicted with the Dryad's Bane debuff, which will deal 4+ damage per second (plus various progression-based damage boosts, and all multiplied by 1× / / ); the minimum damage dealt by the Dryad's Bane debuff is 4 /  /  per second.

World status
The Dryad's reports on Corruption/Crimson/Hallow coverage are accompanied by a status message. She sees Hallow as "good", and Corruption or Crimson as "bad". The Dryad makes the distinction between Corruption and Crimson if they are present in the same world, and will list their percentages separately, though they both contribute to the overall "bad" total in her final report.

Tips

 * Dryads Blessing circle begins roughly 20 blocks from the Dryad, expands to a roughly 40 block radius, and briefly expanding to a 60 block radius before ending.
 * For players creating housing for the Truffle, it would be beneficial to temporarily house the Dryad in or near a Glowing Mushroom biome where she will sell Mushroom Seeds.
 * It is not necessary to build a house, a Queen Statue can be used to teleport her to a Glowing Mushroom biome.
 * Another way on to bring the Dryad to a Glowing Mushroom biome is to use Boulders or Land Mines to kill the Dryad and invalidate all open housing except in the desired biome.
 * Players can obtain items from both evils without using a different world by buying Corrupt or Crimson Seeds (Available while in the Graveyard minibiome) and making an artificial biome.

Trivia

 * A is a nature spirit from Greek mythology, generally depicted as a beautiful young woman. Fittingly, many of the Dryad's possible names take inspiration from either classical literature (e.g., , , ) or female celebrities.
 * This might be the reason that the Arms Dealer appears to flirt with her as shown in one of his quotes, but she states in one of her quotes that she wishes the Arms Dealer would stop pestering her.
 * In the same quote she reveals that she is 500 years old.
 * This is also strange because of the Nurse’s obvious crush on the arms dealer.
 * The Dryad is depicted in a Painting called Dryadisque, which itself is a parody of La Grande Odalisque.
 * Her quote calling the Truffle a "fun guy" plays on the "".
 * The quote "" is a possible joke about the fact that the Dryad is/was a tree.
 * This could also be a reference to her not cleansing the world evil herself despite claiming that she fought the Old One's Army.
 * One of the Dryad's quotes about the player's safety says "Terraria needs you," instead of "[World Name] needs you." This is an oddity among the other quotes.
 * This could be that generated worlds could be portions of the true Terraria, plausibly making Terraria an entire country or nation with true mythology and so on.
 * Calista the Dryad is featured in the Terraria Comic Book from DC Comics.
 * The Dryad also appears in Dungeon Defenders II. Her defenses include summoning: Moss Hornets, Harpies ,Slimes and Angry Nimbuses.
 * The Dryad's quote referencing her time in Etheria and her use of the corruption against the Old One's Army is a reference to her ability in Dungeon Defenders 2 where she can become a corrupted version of herself to do extra damage.
 * One of The Dryad's names (Nissa) comes from the planeswalker Nissa Revane from the trading card game,.
 * Despite this, if the Dryad is killed another Dryad will still arrive, most likely with a different name. Also, the phrasing of the Guide's tip "You should prove yourself by defeating a strong monster. That will get the attention of a dryad." implies there are more than one.
 * The "vital chunks" are likely the two pre-Hardmode bosses who are body parts, which are the Eye and Brain of Cthulhu. (Skeletron might also be part due to Skeletron Prime being a "mechanical reconstruction" of Cthulhu)
 * One of the Dryad's names, Celestia, is a reference to the TV show My Little Pony: Friendship is Magic, which has a princess of the same name.
 * When housed in the Jungle, one of her quotes "I kissed a tree in the Jungle and I liked it" is a reference to the Katy Perry song "I Kissed a Girl".
 * According to Redigit, the Dryad "Isn't actually wearing anything" and "the vines are a part of her body".
