1. What happens to a potion once a hero drinks it? Is it returned to the common pool or is it completely removed from the game and not used again?
2. Similarly, what happens once the overlord spawns a new area and has to place a potion down? Is it taken from the common pool or discards? If taken from the common pool, what happens if there are no potions available there? Same question applies to potions acquired from cards and chests.
3. Does a hero have to be on top of an activated glyph to use it and return to town or is being adjecent to it enough?
Thank you.
