I just discovered the potion medal. The game's description seemed pretty vague. I've now got too much stuff to carry in all my adventure pouches. I need to decide what to carry with me and what to leave behind with the totally unstable item check lady. Help me decide. What affect does the potion medal have?
The potion medal makes the potions that have a time limit last longer (twice as long, I think).
This includes the Guardian, Air, and Stamina potions (and their upgraded versions).
