Ah, that. I'll give you a little clue for now. If you're still confused you can ask for more. It's an enchantment/buffing potion which ingredients are a berry and a dropped item you can only get from one specific enemy.
Ah, there we go. Got it, thanks! Didn't even realize there were any buffing potions. Was wondering what a couple of these items were for.
Ah fair because the buffing potions are rarely being brought up and being referred only once which is in the recipe book's notes.
The NPC that asks you for fruits actually gives some vague hints on how to make these buffing potions but yeah...it's just really too vague
