An eye + pixie dust = magic eye.
Magic eye + helmet = Helmet with Perception + 1
Intestines + empty flask = poison potion.
I know. Both of them will be included when I create Part 5. There are other helmet recipes as well. Try using magic (fancy) feather and magic (glowing) starfish as well.
I don't see 'Poisoned Apple' here (apple + poison, obv).
Not that I have any idea what it does....
True, not directly. This formula works for most of the food and drinks in the game. So I put them in like this:
[-]
Poisoned Food or Poisoned Drink =
Food or Drink +
Ooze Barrel (100% chance to set Poisoned status)[-]
Poisoned Food or Poisoned Drink =
Food or Drink +
Fly Agaric Mushroom (100% chance to set Poisoned status)[-]
Poisoned Food or Poisoned Drink =
Food or Drink +
Poison Flask (100% chance to set Poisoned status)
