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

To get the Demolitionist NPC to move into your world in Terraria, you need to meet specific conditions. The Demolitionist is a valuable NPC who sells explosives, such as bombs, dynamite, and grenades, which are useful for mining, clearing large areas, and fighting enemies. HereÔÇÖs a detailed guide on how to get him to move in, including mechanics, strategies, and tips.

First, the Demolitionist requires two main conditions to spawn. You must have an empty, valid house for him to move into, and you must have at least one explosive item in your inventory. Explosive items include bombs, sticky bombs, grenades, or dynamite. These items can be found in chests underground, purchased from the Merchant NPC, or crafted using materials like gel and bombs. Once you meet these conditions, the Demolitionist will move into the empty house.

To prepare for the DemolitionistÔÇÖs arrival, you should start by building a suitable house. A valid house in Terraria must have walls, a light source, a table or workbench, a chair, and a door or other entrance. The house must also be enclosed and have a certain amount of space. Make sure the house is in a safe area, away from Corruption, Crimson, or other hazardous biomes, as NPCs will not move into houses in dangerous locations. You can check if a house is valid by using the housing menu, which is accessed by talking to the Guide NPC or using the housing query tool.

Once you have a valid house, you need to obtain an explosive item. Early in the game, bombs are the easiest explosive to acquire. You can find them in chests in underground caves or purchase them from the Merchant NPC for 3 silver coins each. If you donÔÇÖt have enough coins, you can gather materials like gel and bombs to craft sticky bombs at a workbench. Having at least one explosive item in your inventory is crucial, as the Demolitionist will not spawn without it.

After meeting these conditions, the Demolitionist will move into the empty house during the next in-game day. If you have multiple empty houses, he will choose one at random. To ensure he moves into a specific house, you can assign him to a particular room using the housing menu. This is useful if you want to place him near other NPCs to maximize happiness, which can reduce the prices of his items.

There are a few common mistakes to avoid when trying to get the Demolitionist to move in. One mistake is not having a valid house. Make sure the house meets all the requirements, including walls, a light source, and furniture. Another mistake is not having an explosive item in your inventory. Double-check your inventory to ensure you have at least one bomb, sticky bomb, grenade, or dynamite. Additionally, avoid placing the house in a dangerous biome, as NPCs will not move into houses in areas like the Corruption or Crimson.

For advanced players, optimizing the DemolitionistÔÇÖs happiness can provide benefits like lower prices and access to unique items. The Demolitionist prefers to live in the Underground or Cavern biomes and likes to be near the Tavernkeep and Mechanic NPCs. Placing him in a house in the Underground biome with these neighbors will increase his happiness. This can reduce the cost of his items, making it cheaper to purchase explosives for mining or combat.

In terms of resource requirements, you will need basic building materials like wood, stone, and torches to construct a house. If you donÔÇÖt have enough materials, you can gather them by chopping trees, mining stone, and crafting torches from gel and wood. For explosives, you will need coins to purchase bombs from the Merchant or materials like gel and bombs to craft sticky bombs. These resources are relatively easy to obtain early in the game, making the Demolitionist one of the first NPCs you can recruit.

Class and equipment considerations are minimal for recruiting the Demolitionist, as the process does not require combat or specific gear. However, having a weapon and armor can help you explore underground caves safely to find bombs or chests. A pickaxe is also useful for gathering materials to build a house. If you are playing as a ranged or melee class, explosives can be a helpful tool for dealing with groups of enemies or breaking through tough blocks.

In summary, getting the Demolitionist to move in involves building a valid house, obtaining an explosive item, and ensuring the house is in a safe location. By following these steps and avoiding common mistakes, you can recruit the Demolitionist early in the game. Optimizing his happiness by placing him in the Underground biome with preferred neighbors can provide additional benefits. With the Demolitionist in your town, you will have access to powerful explosives that can aid in mining, exploration, and combat.
