Apothecary....
Back in 2011 when this was introduced, it was fine... What? It was released only 2 years ago? Oh, well I guess its been outdated from the start.
In all seriousness though.. The potion levels and one sure chance at a (level 1!!) revive per day is silly and terrible. Both paths on both difficulties should have potions that actually matter to people. We are getting into 7*R4's now. A level 2 health potion is just a waste of peoples time and energy even putting it into their champions. All 4 paths should have a potion that actually does something.
Then each level should have at least a guaranteed revive. A level 1 for "easy" and a level 2 for "hard", and then a "rare" chance for a level 3 to pop up on a path. There is no way that this will break the economy of the game. This quest is almost a waste of time now.
I know that about 50% of the game or more is out of date now so this is probably a scream into a void, but these things should be updated regularly with the progress of the game and its players.
