Truffle

The Truffle is an NPC that sells various items such as the Autohammer, Hammush and Mushroom Spear. To get the Truffle to move in, there must be housing in a surface Mushroom Biome during hardmode.

It is highly recommended to prepare a suitable house for the Truffle before defeating the Wall of Flesh, as the Mushroom Spear he sells has the second highest base damage of any spear, the North Pole having the highest, and is available after you defeat one mechanical boss. This is however no longer the case as it is now a requirement to have killed Plantera at least once instead of having to defeat just one mechanical boss.

Once the Truffle has moved into a house, he sells the listed items below.

Trivia

 * It seems that trying to create another biome (jungle) near the Truffle's house fails; it will remain a Mushroom biome.
 * All of his names are named after a type of mushroom or toadstool.
 * The "Truffle Shuffle" line is a reference to the movie "The Goonies"
 * Truffle's line about "everything glowing blue" may imply that the blue mushrooms are hallucinogenic. This may be a reference to the mushroom genus Psilocybe, which are both hallucinogenic, and stain blue when touched.
 * The line "Everytime I see the color blue, it makes me depressed and lazy", may be referring to the fact that he is an underground creature, as opposed to most diurnal animals, who become more active when exposed to the sky. Or it could be a joke because the entire Mushroom Biome (as well as himself) is blue. It could also simply be a joke referring to the slang term "blue" which indicates a person is sad or depressed, thus, seeing the color blue makes him feel "blue".
 * The line "you haven't seen any pigs around here have you? My brother lost his leg to one." refers to the fact that most pigs love Black Truffle mushrooms.
 * The line 'if you cant beat him, eat him' may be a reference to the Children's television show Kirby, Right Back At Ya where that line is used in the show's main theme song.
 * The line "Between you and me, [Dryad's name] is the only one I trust. She is the only one here who hasn't tried to eat me or use me in a potion." this is a reference to how Glowing Mushrooms can be used to create Healing Potions or could be eaten before 1.2 to restore Health.
 * Truffle may refer to King Truffle from the classic SNES game Secret of Mana.
 * Truffle is the only NPC that is required to be housed in a specific biome.
