What are the requirements for the Dryad NPC to move in Terraria?

To have the Dryad NPC move into your world in Terraria, you need to meet specific requirements. The Dryad is a valuable NPC who sells nature-themed items, including seeds, healing potions, and armor. She also provides useful information about the world's corruption or crimson percentage. HereÔÇÖs a detailed guide on how to get her to move in, along with tips and strategies to make the process easier.

First, the Dryad will only move in if you have defeated at least one boss in your world. This is a key requirement. The most common early-game boss to defeat is the Eye of Cthulhu, which can be summoned using a Suspicious Looking Eye at night or spawns naturally once certain conditions are met, such as having 200 health and 10 defense. Other bosses like the Eater of Worlds in Corruption worlds or Brain of Cthulhu in Crimson worlds also count. Once you defeat any of these bosses, the Dryad will become eligible to move in.

Next, you need to provide suitable housing for the Dryad. Housing in Terraria requires a fully enclosed room with walls, a door, a table or workbench, a chair, and a light source. The room must also be at least 6 blocks wide and 10 blocks tall, though larger rooms are fine. Make sure the walls are player-placed and not natural walls, as natural walls do not count for housing. You can check if a room is suitable by using the Housing Query tool, which is available in the inventory menu. If the room is valid, the Dryad will move in as long as there are no other NPCs occupying the space.

When building housing, consider the DryadÔÇÖs happiness. NPCs in Terraria have preferences for specific biomes and neighbors, which affect their happiness. The Dryad prefers living in the Jungle biome and likes to be near the Witch Doctor and Truffle NPCs. If she is happy, she will sell items at a discount and may offer unique items like the Leaf Wand or the DryadÔÇÖs Blessing buff. To maximize her happiness, place her house in the Jungle biome and ensure she is near her preferred neighbors. Avoid placing her near NPCs she dislikes, such as the Arms Dealer or the Steampunker, as this will reduce her happiness.

A common mistake players make is not having enough housing prepared before defeating a boss. If you defeat a boss but donÔÇÖt have a suitable house ready, the Dryad wonÔÇÖt move in immediately. To avoid this, always prepare at least one or two extra houses before engaging in boss fights. This ensures that any new NPCs, including the Dryad, can move in right away.

Advanced players can optimize NPC happiness by creating biome-specific housing clusters. For example, you can build a Jungle biome near your main base using Jungle Grass Seeds and Mud Blocks. This allows you to place the Dryad and other Jungle-loving NPCs in a biome they prefer without having to travel far. Additionally, using pylons can make travel between biomes more efficient, as happy NPCs will sell biome-specific pylons that allow instant teleportation.

Resource-wise, preparing for the DryadÔÇÖs arrival doesnÔÇÖt require much. YouÔÇÖll need basic building materials like wood, stone, and torches to create housing. If you plan to optimize her happiness by building in the Jungle biome, gather Jungle Grass Seeds and Mud Blocks early in the game. These can be found in the Underground Jungle biome, which is accessible once you have decent gear and weapons.

In terms of class and equipment, defeating the first boss to unlock the Dryad doesnÔÇÖt require specialized gear. A basic set of armor like Wood or Iron, along with a decent weapon such as a bow or sword, should suffice. However, having healing potions and buffs like Ironskin or Swiftness can make the fight easier. If youÔÇÖre struggling with the Eye of Cthulhu, consider crafting a platform arena to give yourself more mobility during the battle.

In summary, to get the Dryad to move in, defeat at least one boss, prepare suitable housing, and consider her happiness preferences. Build extra houses in advance, optimize her living conditions by placing her in the Jungle biome near preferred neighbors, and use pylons for efficient travel. With these steps, youÔÇÖll have the Dryad in your world, ready to provide valuable items and information.
