he also need an LSD potion that reveal hidden path or lsd path i don’t know, would be cool to sometime pop a drink and discover entrance to hidden paths, or invisible chest, or detect MIMIC (yeh i saw them somewhere in the files i think XD) or underground hidden monstrosity XD …
maybe he could also have a stand where, to help u get material u could perhaps give him a fish, he’ll let it rot or mix it (anything he wanna experiment XD ) to extract something from it, and will complete a part of the recipe, instead of having to walk the world for 5 fishes to get 1 oil XD …
also one of his line is something like no man is complete until he’s tainted blood, maybe like in the witcher he could give u boosted potion that come at a cost, like, poisoning u increased your hp by a ton, but will decrease ur attack, or just, boosted potion, but u wont be able to take all of them or u’ll basically poison yourself too much and die XD …
