It's written in the game but pretty hidden. (I got the info from the spring next to the chest across the bridge on the left side of the map) So I agree with you completely to make it more obvious.
I actualy did not expect people to figure out so quickly. The growth potion was meant more for late game as you will need it to defeat bosses that might be to big for players to be willing to grind so much.
Thank you for taking the time to figure this out tho. I appreciate the feed back :)
