How do I make the Tavernkeep NPC happy in Terraria?

To make the Tavernkeep NPC happy in Terraria, you need to understand the NPC happiness system, which was introduced in the 1.4 update. This system allows NPCs to have preferences for specific biomes and neighbors, which directly affects their happiness. A happy NPC will offer discounts on their items and, in some cases, sell unique items that are otherwise unavailable. The Tavernkeep is a unique NPC who sells items related to the Old One's Army event, such as sentry summon weapons and armor sets. Keeping him happy is essential if you want to maximize your efficiency in dealing with this event.

The Tavernkeep prefers the Hallow biome and likes to live near the Princess, Wizard, and Golfer NPCs. He dislikes living near the Demolitionist and the Arms Dealer. To maximize his happiness, you should place his house in the Hallow biome and ensure that he is near NPCs he likes while avoiding those he dislikes. The Hallow biome is a bright, colorful biome that is generated after defeating the Wall of Flesh and entering Hardmode. If you haven't reached Hardmode yet, you can create an artificial Hallow biome by planting Hallow seeds or using Holy Water to convert a section of your world into the Hallow.

To set up the Tavernkeep's housing, you will need to build suitable houses in the Hallow biome. Each house should be at least 6 blocks wide and 10 blocks tall, with walls, a door, a table, a chair, and a light source. You can use any type of block for the walls and floor, but make sure the house is fully enclosed and meets the basic requirements for NPC housing. Once the houses are built, assign the Tavernkeep to one of them and place the Princess, Wizard, and Golfer in nearby houses. Avoid placing the Demolitionist or Arms Dealer too close to the Tavernkeep, as this will decrease his happiness.

One common mistake players make is not paying attention to the NPC's preferred biome and neighbors. Placing the Tavernkeep in a biome he dislikes, such as the Corruption or Crimson, will significantly reduce his happiness. Similarly, placing him near NPCs he dislikes will also lower his happiness. Another mistake is not providing enough space between houses. NPCs need to have a certain amount of space between their houses to be considered neighbors. If houses are too close together, the game may not recognize them as separate, which can affect happiness levels.

Advanced techniques for optimizing the Tavernkeep's happiness include creating a dedicated NPC village in the Hallow biome. This village should have houses for all the NPCs the Tavernkeep likes, arranged in a way that maximizes their happiness. You can also use pylons to create a fast travel network between different biomes, making it easier to manage your NPCs and access their shops. Pylons are special items that allow you to teleport between different biomes, but they only work if the NPCs in that biome are happy.

Resource requirements for setting up the Tavernkeep's housing include wood, stone, and other basic building materials. You will also need Hallow seeds or Holy Water to create an artificial Hallow biome if one is not naturally available in your world. Additionally, you may need to gather materials for crafting furniture and other house essentials. If you are in Hardmode, you will need to be prepared to defend your NPC village from Hardmode enemies, which are more powerful and aggressive than pre-Hardmode enemies.

Class and equipment considerations are important when setting up the Tavernkeep's housing, especially if you are in Hardmode. Melee characters should have strong armor and weapons to defend against Hardmode enemies, while ranged characters should have a good supply of ammunition. Magic users should have powerful spells and mana regeneration items, and summoners should have strong minions to protect their base. Regardless of your class, it is a good idea to have a variety of potions and buffs to increase your survivability and combat effectiveness.

In specific scenarios, such as during the Old One's Army event, the Tavernkeep's happiness can directly impact your success. A happy Tavernkeep will sell you powerful sentry summon weapons and armor sets that are essential for defeating the event's waves of enemies. If the Tavernkeep is unhappy, his items will be more expensive, and you may not have access to the best gear for the event. Therefore, it is crucial to keep him happy and ensure that his housing is set up correctly.

In conclusion, making the Tavernkeep happy in Terraria involves understanding the NPC happiness system, building suitable housing in the Hallow biome, and placing him near NPCs he likes while avoiding those he dislikes. By following these steps and avoiding common mistakes, you can maximize the Tavernkeep's happiness and take full advantage of his unique items and discounts. Advanced techniques, such as creating a dedicated NPC village and using pylons, can further optimize your setup and make managing your NPCs easier. With the right preparation and strategy, you can ensure that the Tavernkeep is happy and ready to help you tackle the challenges of Terraria.
