Witch

A Witch is a hostile Mob which can only spawn on a player's Private Island.

Drops
Witches drop, and s.

Behavior
Attacks from a range by throwing Splash debuff Potions. The player will be notified in chat when they are de-buffed from a Potion.

Strategy
Witches aren't really a threat, but if a player wants to kill them efficiently, they can just spam the witches with a sword so fast that they are too busy drinking their healing potion(s) to attack.
