Achievement Guide

There are 10 NPCs throughout the game. You must house them all before the achievement will unlock. A building is considered habitable if it:

  • Is at least 6 blocks tall;
  • Is at least 10 blocks wide;
  • Contains a table;
  • Contains a chair;
  • Contains lighting;
  • Features a door;
  • Features walls.

Note that crafting tables are considered tables, and so will satisfy the table criteria.

This is a list of the available NPCs.

Some NPCs will not automatically be assigned to a house; most notably the Mechanic, Goblin Tinkerer and Wizard. You can either wait for these NPCs to die, in which case they will respawn in an available house, or you can manually assign them to a house.

Once all NPCs have been obtained your achievement will unlock! Congratulations!
