We just discovered that potions may be contained in a chest in basic Descent.

If it says "1 Power Potion", does that mean one potion for each hero?

I checked the rules but they specifically mention only money, curses and treasure cards.

To the best of my knowledge, its just one potion but I could be wrong.

We always distribute it as 1 potion per hero. All other treasures are also either for each hero, or for the team (conquest tokens). There is no other case of 1 player receiving more treasure than the others, so I think potions are dealt out just like cash.

My assumption would also be that it's per hero.

However, it's a power potion in non-RtL, so heroes will have to think very hard about whether it's even worth the 1 movement point it would cost to drink it when they could potentially sell it for 25 gold next time they happen to be at the shop. A big game-changer, this is not.
