Energy Potions
But maybe if for sale they could be:
30 Energy potion (Super) for 5 gold coins
20 E potion (normal) for 3 gold coins
10 E potion (Simple) for 2 gold coins
I guess it would have to be rated with how many refills you used already, 20 gc for potions is way cheaper than 80 for a 120 refill.
OR something like that???
Maybe they would have to be strictly rewards from wheels, I don't know.
Someone that has a helpful Idea on this please post!!
