Guys, eternal download, how to fix?

It's quite obvious how to use Resurrection on Door card: there is a separate button for it each time before you open the door. How do I utilize Resurrection to take from the Treasure discard pile? Anyone?

If mounts and companions were added to the game with the Need for Steed DLC, the game would be much better. Are there any plans for this DLC?

Hi, I would love to play this game with my friends. Does everyone need to buy it? Or can I "host" a game and play with friends on my discord? If all have to buy it, I see no chance to get it popular in my gaming community or another gaming communities.

Not trolling, I've played about 2.5 hours and I'm not getting it.
