I just want to check when each deck should be shuffled. I think it's as follows.

Location Decks: Every time you draw a card.

Mythos Deck: Only at Start of Game

Other World Location Deck: Only at start of game.

Items, Allies, Spells, Skills: Only at start of game.

Gates: Only at start of game.

It's the items etc I'm not sure about. Should I shuffle before each draw or not?

If I left out a deck let me know about that one too.

Thanks all.

It's not 100% right: Mythos and OW locations are shuffled at the start of the game AND when some special cards are drawn (e.g: The Stars Are Right)

All the small cards are shuffled during the setup; the general knowledge / consensum of the board is that after an encounter instructs you to draw a specific card. Like "you may search the common items deck for a Whiskey card and take it": after gaining the card, you shuffle the deck. If the encounter instructs you to gain an item belongng to a category (e.g: "take the first Tome from the Unique Items deck") you reveal cards from the top of the deck until there's a match, but you don't reshuffle afterwards.

Hope this helps

Ah yes, I forgot about the 'except when a card tells you to'.

But thanks, seems like I'm doing it right.
