The Guide is the first NPC a player encounters. He spawns near the player when the world is created. He provides tips mainly aimed at new players and displays possible crafting recipes for items shown to him.
Unlike most other NPCs, the Guide spawns on world creation, before a House is available. He will however move into the first House built. If he is killed, a proper House will need to be built before he can respawn.
On the Desktop, Console, and Mobile, the Guide will defend himself against nearby enemies using a Wooden Bow and arrow, firing Wooden Arrows initially and then upgrading to Flaming Arrows in Hardmode.
The Guide's Advice
Some quotes may vary depending on what version of Terraria is being played.
At the beginning of the game:
- "You can use your pickaxe to dig through dirt, and your axe to chop down trees. Just place your cursor over the tile and click!"
- "If you want to survive, you will need to create weapons and shelter. Start by chopping down trees and gathering wood."
- "Press Esc to access your crafting menu. When you have enough wood, create a workbench. This will allow you to create more complicated things, as long as you are standing close to it."
- "You can build a shelter by placing wood or other blocks in the world. Don't forget to create and place walls."
- "Once you have a wooden sword, you might try to gather some gel from the slimes. Combine wood and gel to make a torch!"
- "To interact with backgrounds, use a hammer!"
- "You should do some mining to find metal ore. You can craft very useful things with it."
- "Underground are crystal hearts which can be used to increase your max life. You can smash them with a pickaxe."
- "There are many different ways you can attract people to move in to our town. They will of course need a home to live in."
- "In order for a room to be considered a home, it needs to have a door, a chair, a table, and a light source. Make sure the house has walls as well."
- "Two people will not live in the same home. Also, if their home is destroyed, they will look for a new place to live."
- "You can use the housing interface to assign and view housing. Open your inventory and click the house icon."
If ore is inside your inventory:
- "Now that you have some ore, you will need to turn it into a bar in order to make items with it. This requires a furnace!" 
- "You can create a furnace out of torches, wood, and stone. Make sure you are standing near a work bench." 
If bars are inside your inventory:
- "You will need an anvil to make most things out of metal bars." 
- "Anvils can be crafted out of iron or lead, or purchased from a merchant." 
If you have unobtained NPCs:
- "If you want a merchant to move in, you will need to gather plenty of money. 50 silver coins should do the trick!"
- "For a nurse to move in, you might want to increase your maximum life."
- "If you had a gun, I bet an arms dealer might show up to sell you some ammo!"
- "You should prove yourself by defeating a strong monster. That will get the attention of a dryad."
- "Make sure to explore the dungeon thoroughly. There may be prisoners held deep within." (Reference to the Mechanic in the dungeon)
- "Perhaps the old man by the dungeon would like to join us now that his curse has been lifted."
- "Hang on to any bombs you might find. A demolitionist may want to have a look at them."
- "Are goblins really so different from us that we couldn't live together peacefully?" 
- "If you combine lenses at a demon altar, you might be able to find a way to summon a powerful monster. You will want to wait until night before using it, though."
- "You can create worm bait with rotten chunks and vile powder. Make sure you are in a corrupt area before using it."
"You can create a bloody spine with vertebrae. Make sure you are in a crimson area before using it."
- "Demonic altars can usually be found in the corruption. You will need to be near them to craft some items."
"Crimson altars can usually be found in the crimson. You will need to be near them to craft some items."
- "You can make a grappling hook from a hook and 3 chains. Skeletons found deep underground usually carry hooks, and chains can be made from iron bars or lead bars."
- "If you see a pot, be sure to smash it open. They contain all sorts of useful supplies."
- "There is treasure hidden all over the world. Some amazing things can be found deep underground!"
- "Smashing a shadow orb will sometimes cause a meteor to fall out of the sky. Shadow orbs can usually be found in the chasms around corrupt areas."
"Smashing a crimson heart will sometimes cause a meteor to fall out of the sky. Crimson hearts can usually be found in the chasms around crimtane areas."
- "You should focus on gathering more life crystals to increase your maximum life."
- "If you gather 5 fallen stars, they can be combined to create an item that will increase your magic capacity." (now only needs 3 fallen stars to make 1 mana star, prior to the 1.3 update on Steam and OS)
- "Stars fall all over the world at night. They can be used for all sorts of useful things. If you see one, be sure to grab it because they disappear after sunrise." 
- "Your current equipment simply won't do. You need to make better armor."
- "I think you are ready for your first major battle. Gather some lenses from the eyeballs at night and take them to a demon altar."
- "You will want to increase your life before facing your next challenge. Fifteen hearts should be enough."
- "The ebonstone in the corruption can be purified using some powder from a dryad, or it can be destroyed with explosives."
- "Your next step should be to explore the corrupt chasms. Destroy any shadow orb you find."
- "There is an old dungeon not far from here. Now would be a good time to go check it out."
- "You should make an attempt to max out your available life. Try to gather twenty hearts."
- "There are many treasures to be discovered in the jungle, if you are willing to dig deep enough."
- "The underworld is made of a material called hellstone. It's perfect for making weapons and armor."
- "When you are ready to challenge the keeper of the underworld, you will have to make a living sacrifice. Everything you need for it can be found in the underworld."
- "Ostara's hare is corrupting the wildlife. Defeat it to change things back to normal."
- "I hear [Name of Merchant] sells a special ring that grows in power when gifted to one's true love."

"Make sure to smash any crimson altar you can find. Something good is bound to happen if you do!"
- "Souls can sometimes be gathered from fallen creatures in places of extreme light or dark."
- "I heard there was a powerful wizard who lives in these parts. Make sure to keep an eye out for him next time you go underground."
The guide may have any of the following names: Guide/Names
In addition to tips, the Guide also has various quotes:
- "Greetings, [Name of Player]. Is there something I can help you with?"
- "I am here to give you advice on what to do next. It is recommended that you talk with me anytime you get stuck."
- "They say there is a person who will tell you how to survive in this land... oh wait. That's me."
- "You should stay indoors at night. It is very dangerous to be wandering around in the dark."
During a Blood Moon:
- "Hey, buddy, do you know where any deathweed is? Oh, no reason; just wondering, is all." (Reference that Deathweed blooms on Blood Moons.)
- "If you were to look up, you'd see that the moon is red right now."
- "You can tell a Blood Moon is out when the sky turns red. There is something about it that causes monsters to swarm."
During a Party:
- "Never been to a party before? You might want to check around with the others. People sometimes bring out special party favors."
When the Tavernkeep is present:
- "Normally I'd try to teach you all about the Old One's Army, but you should probably ask [Name of Tavernkeep] about that."
- "The Oktober festival is here! The Merchant has brewed up some of his famous ale especially for the occasion and the Clothier is selling traditional festival clothes." (Only if Merchant and Clothier are present)
- "New Year is here! The Demolitionist is selling special weaponry to light up the skies, and the Clothier is selling traditional festive attire."
- The Guide's crafting tips for weapons show adjusted damage based on any bonuses the player currently has equipped, such as the Molten armor's set bonus. Unequip damage-adjusting items while speaking to the Guide to see base damage. This also applies to critical strike chance.
- While NPCs cannot usually be attacked directly by players, the Guide Voodoo Doll will allow players to attack the Guide.
- The Guide, like any other friendly NPC, will not respawn unless it is day.
- The Guide must be alive to summon the Wall of Flesh, otherwise the Wall of Flesh will not spawn.
- The Guide will not have many useful tips after unlocking Hardmode, except hinting about destroying Altars and finding Souls of Light and Night underground.
- The Guide will incorrectly display advice for fighting the Eater of Worlds, such as destroying Shadow Orbs and exploring Corruption Chasms in a Crimson world. After defeating the Wall of Flesh, he will display his Hardmode messages alongside the bugged Pre-Hardmode messages about the Corruption, due to the Eater of Worlds having not been defeated.
- One of the Guide's names is Andrew, named for Andrew Spinks (aka Redigit), the lead developer of Terraria. The Green Cap is dropped if a Guide with that name (or any name) is killed.
- Terraria's lead developer, Redigit, said during an AMA on Reddit that he created the Guide Voodoo Doll so players could get revenge on him for always opening the door.
- The Guide is depicted in two paintings, Guide Picasso and The Creation of the Guide.
- During the New Year, the Guide may say his quote, even if the Demolitionist and Clothier aren't present. This will reveal the names of them when they are eventually unlocked.
