Updated for Town Hall 18 (October 2026).
The Night Witch is a ranged splash troop in the Builder Base that keeps calling in Bats while she fights. She unlocks at Builder Barracks level 8 (Builder Hall 6), starts at level 9, and maxes at level 20 on Builder Hall 10. Her Builder Base 2.0 ability, Bat Swarm, is a one-time tap that releases a pack of enraged Bats.
How the Night Witch works
She is the Builder Base cousin of the Home Village Witch, with Bats in place of Skeletons. She attacks the closest building from 4 tiles away with a fast splash shot (one every 0.7 seconds, the quickest attack of any Builder Base troop). Guard Post troops and Zappies pull her off her target if they attack her or a troop beside her.
Every few seconds she summons a small group of Bats, up to a cap that rises with level. Bats are melee air units that hit any building nearby, so ground-only defenses cannot touch them. Only one Night Witch fits in each Army Camp slot.
Bat Swarm is a one-time active ability you have from her very first level. Tap her and she releases a larger group of enraged Bats that deal extra damage for a few seconds. The number of Bats in the swarm grows from 7 at level 9 to 11 at level 20.
Unlock and level stats
Build Builder Barracks level 8 at Builder Hall 6 to unlock her. Research after that happens in the Star Laboratory and costs Builder Elixir.

How to attack with Night Witches
- Put a tank in front. A Boxer Giant or the Battle Machine soaks the hits while she builds up Bats behind it. Leave a few tiles between them so one Multi Mortar volley cannot hit both.
- Ranged troops drift around the edge of a base. Clear the outside with Raged Barbarians or Bombers first so she follows the push inward.
- Dropping her in a corner gives her time to stack Bats before she reaches anything. Check that corner for a Mega Mine first, or lead with the Battle Machine.
- Wait to tap Bat Swarm until a regular wave of Bats is already out and the group is close to a defense. The enraged Bats then land on targets right away.
- Watch the Lava Launcher. Its lava pools linger and she is slow, so a tank does not save her if she walks through them.
How to defend against Night Witches
- The Bats are the threat that grows. Air Bombs, the Roaster and Mines set to air wipe groups of them. Protect those so your other defenses get time to kill her.
- Bats do nothing to shield her from ground fire, unlike the Witch’s Skeletons. Double Cannons, the Giant Cannon, the Multi Mortar and the Mega Tesla all hit her directly.
- The Giant Cannon and Lava Launcher reach Night Witches standing behind a tank.

FAQ
What Builder Hall unlocks the Night Witch?
Builder Hall 6, which lets you build Builder Barracks level 8.
Do Night Witch Bats target defenses?
No. They hit whatever building is nearest, so you may need to clear outside buildings to steer them.
When should I use Bat Swarm?
When her normal Bats are out and the group is next to a defense. You only get it once per battle.
