There should be good and bad witches. The bad ones use bad potions on you, like weakness, slowness and the good witches should trade good potions with you like villagers do now with other things.. like swiftness, regeneration, etc.
Their hats might have different colors so you can tell the difference.
I don't really agree with this. It's kinda useless, and you haven't elaborated on anything here. Where would it spawn? What purpose would it serve besides tradng potions? What would it look like? No support here.
That would be neat! I like good witches Maybe they could live in swamp huts too, so if you see a swamp hut there might be a good witch insted of a bad one. Suppot!
