Quick question, how do you get whatever item the "some potion" needs to be combined with? That's the only part of the game I'm confused at. I could keep randomly combining items, but I don't want to keep wasting them.
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.
