Each player starts with 8 Stamina. Stamina is incredibly important, not just for doing actions, but because at the end of the game it’ll be the players with the most Stamina who decide who escapes. If a player is ever reduced to 0 Stamina they immediately return to the Lounge and have to rest the following round.
Apart from chat, the actions you can do each round are below. You cannot spend Stamina doing an action if it would take you to 0 Stamina.
Give -Costs 0 Stamina- Give another player in the same Location one of your Items.
Attack -Costs 1 Stamina- Deal 1 Stamina damage to a player or Monster in your Location. Some Items & Events will say Attack X, in which case you deal X Stamina damage instead.
Steal -Costs 1 Stamina- Choose a player in the same location, look through their Items, and take one of them. The chosen player gets to do a Non-Steal Action before you look through their Items.
Use -Costs 0 Stamina- Use an Item (all Items which can be used will say how to use them. If they cost Stamina they will say).
In addition during the Exploration Phase there are three additional actions:
Search- Costs 1 Stamina- Take a Card from the Location deck. Your first Search each round costs 0 Stamina.
Change Location- Costs 1 Stamina- Discard down to your Item Limit and go to a different Location. If you return to the Lounge this costs 0 Stamina.
Rest (Lounge Only)- Take a Card from the Lounge deck and gain 1 Stamina (2 if currently on 0). You only gain the Stamina at the end of the phase. If you do any other action this round you do not get the Stamina.
Finally during the Planning Phase there’s one additional action players can do, which is a Seance. This is how to verify who is Human/Possessed. During setup a small deck is made up with a card for each Human player and a card saying ‘Possessed’ for each Possessed player. During a Seance, one player gets to look at the top card of that deck:
Seance- Costs 0 Stamina- Remove a Talisman and Bloody Item from the game (must be in your possession). Take a card from the Seance deck and tell the other players what it says. If you are Human you must tell the truth, otherwise you can lie. If you say the name of another player, that player is Registered as Human. Only players not Registered as Human can perform a Seance. That card is then removed from the game.
