How do I get the Cyborg NPC to move in Terraria?

To get the Cyborg NPC to move into your world in Terraria, you need to meet specific conditions. The Cyborg is a late-game NPC who sells high-tech items, such as rockets, nanites, and the Proximity Mine Launcher. He is essential for players who want to progress further in the game, especially during the endgame. Here is a detailed explanation of how to get the Cyborg to move in, along with tips, strategies, and considerations.

First, the Cyborg will only appear after you have defeated Plantera, one of the game's major bosses. Plantera is a Hardmode boss found in the Underground Jungle biome. To summon Plantera, you need to destroy a Plantera's Bulb, which spawns randomly in the Underground Jungle after defeating the three Mechanical Bosses: The Destroyer, Skeletron Prime, and The Twins. Defeating Plantera is a significant milestone in Terraria, as it unlocks new content and makes the Cyborg available.

Once Plantera is defeated, the Cyborg will have a chance to spawn, but only if there is an available house for him. To create a suitable house, you need to build a room that meets the basic housing requirements. The room must have walls, a light source, a flat surface item like a table or workbench, and a comfort item like a chair. The room must also be enclosed with walls and have a door or platform entrance. Make sure the house is in a safe area, away from Corruption, Crimson, or Hallow biomes, as these can prevent NPCs from moving in.

After defeating Plantera and preparing a house, the Cyborg will move in automatically. However, there are a few things to keep in mind to ensure this process goes smoothly. One common mistake is not having enough houses available. If all your houses are occupied by other NPCs, the Cyborg will not move in. Always check your housing menu to ensure there is at least one empty house. Another mistake is placing the house in an unsuitable biome. While the Cyborg does not have a specific biome preference, placing him in a biome with high enemy spawn rates can make it difficult for him to stay alive.

To optimize the Cyborg's arrival, you can prepare in advance by building multiple houses in a central location. This makes it easier to manage NPCs and ensures you always have space for new arrivals. Additionally, consider placing the Cyborg near other NPCs he likes, such as the Steampunker and the Mechanic. This will increase his happiness, which can lead to discounts on his items and the sale of the Teleporter, a useful item for fast travel.

Resource requirements for getting the Cyborg are minimal, as you only need to build a basic house. However, defeating Plantera requires significant preparation. You will need strong weapons, armor, and accessories to take on the Mechanical Bosses and Plantera. For melee players, weapons like the Terra Blade or True Night's Edge are effective. Ranged players should use weapons like the Megashark or Chlorophyte Shotbow. Mages can use the Rainbow Rod or Golden Shower, while summoners should focus on the Spider Staff or Optic Staff. Make sure to have potions like Ironskin, Regeneration, and Swiftness to boost your survivability and mobility during the fight.

In terms of advanced techniques, you can speed up the process by farming Plantera's Bulbs. After defeating the Mechanical Bosses, explore the Underground Jungle and mark the locations of Plantera's Bulbs. This way, you can quickly summon Plantera once you are ready. Additionally, consider building an arena in the Underground Jungle to make the fight easier. Use platforms, campfires, heart lanterns, and honey pools to increase your health regeneration and mobility.

In summary, getting the Cyborg to move in requires defeating Plantera and having an available house. Prepare for the fight by gathering strong weapons, armor, and potions. Build a suitable house in a safe location and ensure it meets all housing requirements. Avoid common mistakes like not having enough houses or placing the house in a dangerous biome. By following these steps and strategies, you can successfully get the Cyborg to move in and take advantage of his high-tech items.
