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 an available house during the next in-game day.

To prepare for the DemolitionistÔÇÖs arrival, you should first ensure you have a suitable house. A valid house in Terraria must meet specific requirements. It needs to be at least 6 blocks wide and 10 blocks tall, with walls, a door, a table or workbench, a chair, and a light source like a torch. The house must also be fully enclosed with walls, including a background wall that is player-placed, not natural. You can check if a house is valid by using the housing menu, which is accessible by pressing the house icon in your inventory.

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 by breaking pots. If you have the Merchant NPC, you can purchase bombs from him for 3 silver coins each. Alternatively, you can craft bombs using gel and bombs at a workbench. Gel is obtained by defeating slimes, which are common enemies in the early game.

After you have an explosive item in your inventory, the Demolitionist will spawn during the next day cycle. If you have multiple empty houses, he will move into the first available one. If you want him to live in a specific location, make sure that house is the only one available or assign him to a specific house using the housing menu.

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 your house meets all the requirements, including having a background wall and being fully enclosed. Another mistake is not having an explosive item in your inventory. Even if you have bombs stored in a chest, they wonÔÇÖt count unless they are in your inventory. Additionally, if you have other NPCs waiting to move in, they might take priority over the Demolitionist. To avoid this, make sure you have enough houses for all NPCs.

For advanced players, you can optimize the DemolitionistÔÇÖs happiness by placing him in the right biome and near preferred neighbors. The Demolitionist prefers the Underground biome and likes to live near the Tavernkeep and the Mechanic. Keeping him happy will reduce the prices of his items and may unlock special items like the Party GirlÔÇÖs Party Center. To maximize his happiness, build his house in the Underground biome and place the Tavernkeep and Mechanic nearby.

In terms of resource requirements, you donÔÇÖt need much to get the Demolitionist to move in. A basic house can be built with wood, which is easy to gather from trees. Bombs or other explosives can be found or purchased early in the game, so you donÔÇÖt need advanced materials. However, if you want to optimize his happiness, you may need to gather additional resources to build in the Underground biome and create suitable housing for his preferred neighbors.

Class and equipment considerations are minimal for getting the Demolitionist to move in. Any class can meet the requirements, as they only involve building a house and obtaining an explosive item. However, if you plan to explore underground to find bombs or build in the Underground biome, having good mobility equipment like Hermes Boots or a grappling hook can help.

In summary, getting the Demolitionist to move in requires a valid house and an explosive item in your inventory. Build a suitable house, gather bombs or other explosives, and ensure the house is the only one available if you want him to move in immediately. Avoid common mistakes like not having a valid house or forgetting to keep explosives in your inventory. For advanced players, optimize his happiness by placing him in the Underground biome near the Tavernkeep and Mechanic. With these steps, youÔÇÖll have the Demolitionist in your town, ready to supply you with powerful explosives for your adventures.
