The guide will always provide you with helpful tips and recipes for crafting items. However, his origins and unusual connections to this world remain a mystery.
— Description from the Bestiary
The Guide is the very first NPC the player encounters after creating a new map. They offer advice that is primarily useful for new players. Unlike other NPCs, they don't require a room in your house to stay, but they will immediately occupy a free room as soon as you build one. Furthermore, before update 1.0.3, they were immune to all damage except lava, but even after their death, a message about their arrival would appear after a few minutes, and they would reoccupy the empty room.
After the 1.0.5 update, it can now prompt players what can be done with a certain material if shown to them, and, most importantly, if you move the cursor away from the item's window, a text box will appear telling you which workbench the item is crafted at.
Version 1.0.5 introduced the Guide's Voodoo Doll (dropped by the Voodoo Demon), which allows you to kill him. However, like any NPC, he will return after a while under a different name. Since update 1.3, he uses a wooden bow for defense.
Since version 1.3, he defends himself against monsters with a wooden bow, using wooden arrows. After hitting a target in Hardmode, his arrows become fiery.
