Terraria - The Mechanic, The Tinkerer, and The Wizard

Do you want one, or all, of the three new NPC's? Can't figure out how to get them to move into a house because they won't even spawn? Well here is a little guide to help! The Goblin Tinkerer can be found tied up basicly anywhere as long as it's at or past the Underground layer. Talking to him will set him free. The Mechanic can be found tied up somewhere in the dungeon. The wizard can be found tied up underground somewhere. Having trouble freeing them? Here's a tip! Autopause has to be OFF in order to set them free, it can be turned off in the options of the main menu.
