My only criticism is the lack of a way to increase the junk and balls size. Other then that can't wait to see how the development goes. Also holy moly the size stat is busted
I assume you're talking about the Ego potion? You must defeat the lich from the notice board called "Quest: Kill the Lich". It will ask you to talk to the Apothecarist. She is located in the shop to the left of the blacksmith (or behind you at the starting area.) with the sign "Potions" out front. Once you kill the lich a few new items will unlock in her shop, one such is the Ego Potion you're looking for. However, it does become irrelevant quickly if you just win battles in dungeons and even more so against strong (huge) enemies.
