Adventurer

The Adventurer is a Town NPC that sells several unique items and also assigns quests to players. Quest objectives generally involve killing a certain amount of specific enemies or getting him a quest item from particular enemies or from crafting, for which he dispenses various rewards.

The Adventurer is first encountered as Frozen Adventurer laying down in a Snow Cozy House. He will move in when:
 * The player has interacted with him and unbound him.
 * There is a vacant house.

When threatened, he will cast a crystal above his head that shoots bolts at enemies.

Quests
The Adventurer gives out a quest each day, resetting at 4:30 a.m. every in-game day. Quests can be started by clicking on the "Quest" button, the Adventurer will tell the player to retrieve an item and give a tip on where to find the quest item.

After a quest has been completed, the Adventurer will reward the player with an Adventurer's Loot Box, and an extra item for some of the quests.

Trivia

 * A huge chunk of the Adventurer's names come from other adventurers. (Indiana comes from Indiana Jones. Steve could possibly be Minecraft's own, John could be a reference to John Smith, etc.)
 * The quote about being a professor backs up the theory that Indiana is a reference to Indiana Jones.
