Guide is the first NPC that the player will encounter in any given world. Unlike other NPCs, he does not need a house, but will move into the first one built, which will often be yours, or the first house you have explored; floating islands or the underground houses in giant trees. If the Guide dies before a house is built, he will not respawn until there is a suitable house in the world.
The Guide provides tips to new players in order to help them learn the basics of the game. After every available tip has been said, he will cycle through them again.
The Guide will also provide all crafting recipes for any item that the player shows him via the "Crafting" option.
"Greetings, <player name>. 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."
During the Night
"You should stay indoors at night. It is very dangerous to be wandering around in the dark."
"You can tell a Blood Moon is out when the sky turns red. There is something about it that causes monsters to swarm."
"Hey, buddy, do you know where any deathweed is? Oh, no reason; just wondering, is all."
"If you were to look up, you'd see that the moon is red right now."
"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 and placed objects, use a hammer!"
"You should do some mining to find metal ore. You can craft very useful things with it."
After some mining
"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."
"You will need an anvil to make most things out of metal bars."
" Anvils can be crafted out of iron, or purchased from a merchant."
"Underground are crystal hearts that can be used to increase your max life. You will need a hammer to obtain them."
"If you gather 5 fallen stars, they can be combined to create an item that will increase your magic capacity." Note: 10 Fallen Stars are needed for Mana crystals prior to 1.2.
"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."
Tips regarding NPCs
Note: Tips targeting a specific NPC will only show up if the respective NPC isn't present
"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, chair, 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 you inventory and click the house icon."
"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!"
"Hang on to any bombs you might find. A demolitionist may want to have a look at them."
"You should prove yourself by defeating a strong monster. That will get the attention of a dryad."
Once you defeated Skeletron:
"Make sure to explore the dungeon thoroughly. There may be prisoners held deep within."
"Perhaps the old man by the dungeon would like to join us now that his curse has been lifted."
After first Goblin event:
"Are goblins really so different from us that we couldn't live together peacefully?"
Tips regarding Bosses
"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."
"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."
"You should focus on gathering more heart crystals to increase your maximum life."
Tips for first boss fight
When you have Iron or lower equipment
"Your current equipment simply won't do. You need to make better armor."
When you have silver or better equipment and didn't battled the Eye of Cthulhu yet.
"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."
When Eye of Cthulhu was already battled
"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. Find and destroy any shadow orb you find."
Tips for late Pre-Hardmode
"There is a 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."
"Make sure to smash any demon 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 somewhere in these parts. Make sure to keep an eye out for him the next time you go underground."
Note: Upon adding a new name, make sure you add it in alphabetical (ABC) order.
Chris (possibly only on the mobile versions)
Eva (possibly only in 1.1)
Joost (possibly only in mobile version)
You may want to build two houses, first one for the Guide, second one for yourself.
Killing the Guide with a Guide Voodoo Doll by dropping it in lava is necessary for unlocking Hard Mode. See Wall of Flesh or Guide Voodoo Doll for more.
The Guide has a tendency to get stuck in caves, holes, etc. To avoid this, cover up any holes or caves within the Guide's area or just cover him up until you build a house for him.
In previous versions of the game, the Guide would wander around even at night, opening doors and letting hostile mobs in.
The Guide's hair seems to be a deformed version of Hair 2.
In the iOS version of Terraria, the Guide can no longer tell you crafting recipes. The recipes that include any or all of your items you have are displayed when you are crafting.
There is a picture in the game that appears to be the Guide called Guide Picasso
When the Guide is named "Andrew", he will drop a Green Cap upon death, probably because Redigit's name is Andrew.
The Guide will take damage from things like the Rainbow Gun if you equip the Guide Voodoo Doll after you cast the spell. If you remove the Doll, it will immediatly stop the damage.
The only time the guide asks a question is on Blood Moons when he asks if the player has seen any Deathweed.
Sometimes the Guide will say "Hang on to any bombs you might find. A Demolitionist may want to to take a look at them" when the Demolitionist is already present.
Sometimes the Guide will automatically craft an item using your items when asking for a recipe. (Console only)
Sometimes the Guide might not spawn back too fast or never.
On the mobile versions, the Guide can say "You should make an attempt to max out your available life. Try to gather 20 hearts.", while you can only have a maximum of 10 hearts (200 health) yet.
Guide now tells you what you can craft from any material (when that item states it is a Material)
Can now be killed by monsters
