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 or Skeletron has been defeated.

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

When enemies are nearby, the Dryad will periodically grant the Dryad's Blessing buff to players in the vicinity and displays a leaf barrier effect. The buff grants +8 defense, increased health regeneration, and gives the player contact damage. Enemies touching the leaf circle of the barrier will take 1 point of damage per second, (more damage per second if you have defeated more bosses and x1.5 during Expert mode).

On the, the Dryad prefers to live in the Jungle. She likes the Witch Doctor and the Truffle, dislikes the Angler and Zoologist and hates the Golfer.

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 "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

 * 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.

Names
The Dryad may have any of the following names:
