I think alchemy is very hard at first, but once you understand it, it is very rewarding. especially if you want groshen. also the potions are very powerful especially lazarus and padfoot. Lazarus is the cheapest easiest potion and sells for the most. If the potions weren’t so rewarding all that work would definitely be worth less. Not going to lie though, took me a good 2-3 hours to figure out how the alchemy worked.
