Minecraft Dungeons:Witch

Witches are hostile mobs that attack by throwing potions which create clouds of damaging gas.

Appearance
Witches have purple robes, a green smock underneath, and a black hat with a belt that holds a green stone. They are most common in Soggy Swamp and can sometimes be found elsewhere such as Soggy Cave.

Behavior
Witches concoct and throw foul brews to attack players and pets. On impact they explode, creating noxious potion clouds. The potion attack has a small circular radius, and disappears after a short time, all the while causing constant damage to anyone inside its radius. Witches attack from a short distance away and retreat back once they have done so.

When injured, they can heal themselves by drinking potions.
