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.

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 either 1x in Classic Mode, in Expert Mode, or  in ); 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 "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.

Names
The Dryad may have any of the following names:
