1) How many times per player turn can an action be used? I'm assuming once-per-turn, but I can't find a specific rule saying that.
2) If an action is prefaced by a location (Battlefield, Quest, Kingdom), does that mean that action can only be used if that card is placed in that location? Or can it only be used during that phase of the turn? Again, I'm assuming card location, but I can't find that in the rules.
