what if witches wont attack you when wearing a pumpkin head and let you trade with them for potions and ingredients.
the logic behind this is that the pumpkin head can be like an occult mask symbol that signifies that the player is on her side. this would be a better way for players to get potions before the nether instead of the brewing stands now present in villages.
This would also make the witch seem smarter and less midlessly evil than the zombie or skeleton.
Now that the witch is neutral this is less complicated
Maybe they would sell some secret awesome potion that the player don’t know how to brew?
Perhaps, along with selling potions, you can sell her ingredients. Also, what about making them spawn less often so finding one to trade with is harder.
