// NPCs
Certain floors contain friendly (or at least non-hostile) characters. Walk into their tile to interact. Most NPCs open a menu; some will say something first.
The Merchant appears on every Rest Floor (every 5th floor). Walk onto his tile to open his shop. He sells consumable items, rings, weapons, and armor. His stock is randomly generated per rest floor — not every item is always available.
Items available in the Merchant's stock (randomized per floor):
See Items for specific prices and effects. The Merchant does not restock within a floor session. What you see is what's available.
You can sell weapons and armor you no longer want. The buyback value is lower than the purchase price. Selling is permanent — there is no buyback.
The Gambler appears on rest floors. He runs a simple wagering minigame. The entry fee is 200 Bitcoins. He only engages you if you can afford to play.
Erok is a recurring character who appears on certain floors and rest floors. Walk into his tile to chat. He has things to say.
On the Rest Floor at depth 30, a special non-hostile version of the Gay Cocksucking Vampire stands near the center of the floor and offers you access to the Vampire Raid.
Walk up to them and interact to see the raid offer. For details on the Vampire Raid itself, see Vampire Raid.
