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

The Tavernkeep is a unique NPC in Terraria who sells items related to the Old One's Army event, such as Defender Medals, sentry summon weapons, and armor sets. To get the Tavernkeep to move in, you need to meet specific requirements and follow certain steps. HereÔÇÖs a detailed guide on how to achieve this.

First, the Tavernkeep can only appear after you have defeated the Eater of Worlds or the Brain of Cthulhu, depending on whether your world has Corruption or Crimson. These bosses are early-game challenges, so youÔÇÖll need to prepare accordingly. For the Eater of Worlds, youÔÇÖll need to break Shadow Orbs in the Corruption biome, which requires at least a Nightmare Pickaxe or better. For the Brain of Cthulhu, youÔÇÖll need to break Crimson Hearts in the Crimson biome, which also requires a pickaxe of similar strength. Both bosses can be summoned using Worm Food or Bloody Spine, respectively, which are crafted from materials found in their respective biomes.

Once youÔÇÖve defeated one of these bosses, the Tavernkeep will start appearing as a random encounter in the world. He can spawn in any biome, but he is most commonly found in the Cavern layer. When you encounter him, he will be lying on the ground, similar to the Bound Goblin or Bound Wizard. You need to talk to him to free him, and he will then become available to move into your town.

To ensure the Tavernkeep moves in, you need to have a suitable house ready for him. The house must meet the basic requirements for any NPC: it must be at least 6 blocks wide and 10 blocks tall, have walls, a door, a table, a chair, and a light source. The house must also be in a valid biome, as some biomes can prevent NPCs from moving in. Once the house is ready, the Tavernkeep will move in automatically if there are no other NPCs waiting to occupy the space.

One important tip is to make sure your world has enough housing for all NPCs. If you have too many NPCs and not enough houses, the Tavernkeep may not move in even if youÔÇÖve freed him. You can check the housing menu to see if there are any available houses. If not, youÔÇÖll need to build more.

A common mistake players make is not exploring enough to find the Tavernkeep. Since he spawns randomly in the Cavern layer, youÔÇÖll need to spend some time exploring underground. Using items like Spelunker Potions or the Metal Detector can help you locate him more easily. Another mistake is not preparing adequately for the Eater of Worlds or Brain of Cthulhu fights. These bosses can be challenging if youÔÇÖre not properly equipped, so make sure to have good armor, weapons, and potions before attempting them.

For advanced players, optimizing the TavernkeepÔÇÖs happiness can be beneficial. NPC happiness affects the prices of their items, so placing the Tavernkeep in a biome and with neighbors he likes can save you money. The Tavernkeep prefers the Hallow biome and likes the Princess and the Goblin Tinkerer as neighbors. Placing him in the Hallow with these neighbors will maximize his happiness.

Resource-wise, youÔÇÖll need basic building materials like wood, stone, and torches to create a house for the Tavernkeep. For the boss fights, youÔÇÖll need weapons and armor appropriate for your current progression. For the Eater of Worlds, weapons with piercing damage like the Vilethorn or a bow with JesterÔÇÖs Arrows are effective. For the Brain of Cthulhu, weapons with area damage like grenades or the Blade of Grass work well.

In terms of class and equipment, any class can summon the Tavernkeep, but melee characters might have an easier time with the Eater of Worlds due to their high defense. Ranged and magic users can also be effective if they keep their distance and use piercing or area-of-effect attacks. Summoners might struggle a bit early on but can still contribute with minions.

In summary, to get the Tavernkeep to move in, defeat the Eater of Worlds or Brain of Cthulhu, explore the Cavern layer to find him, and have a suitable house ready. Prepare well for the boss fights, ensure you have enough housing, and consider optimizing his happiness for better prices. With these steps, youÔÇÖll have the Tavernkeep in your town in no time.
