The Witch is a splash-damaging Dark Elixir unit in the Home Village that can only be obtained if Town Hall reaches level 9 and the Dark Barracks is upgraded to level 5.
Strategy
Offensive:
The Witch is advised as a support trooper and should be positioned close to the rear of an attack due to her low hitpoints. Witches shouldn’t be grouped together because a mortar may destroy them all. Furthermore, the Witch’s Skeletons provide as useful diversion when occupying defense structures.
Defensive:
The Giant Bomb can destroy any adjacent Skeletons within its radius and deal significant damage to Witches when they attempt to defend themselves.
Witches can be rather formidable when defending in Clan Castles, particularly if the attacker is unprepared (especially if there are two or more in the same Clan Castle).
