The Tavernkeep is a unique NPC vendor that accepts only Defender Medals as currency for most items, instead of coins. He will only become accessible after the player has defeated the Eater of Worlds or Brain of Cthulhu. Once this criterion is met, he will appear as an unconscious man spawning in any layer of the world. Similar to bound NPCs, talking to him allows him to claim a House and respawn when killed.The Tavernkeep's sentry summon weapons are associated with the Old One's Army event, and at first, they can only be used within that event. They function elsewhere only after the event is completed once successfully. Each of the Tavernkeep's sentry summon weapons come in three tiers: Rod, Cane, and Staff; with the Staff being the most expensive and the most powerful.
When threatened, he throws mugs of ale at enemies.
