Bat Spell — Clash of Clans
Spells
Updated: 18 September 2026 · By the Goblins Farm team
The Bat Spell spawns a swarm of bats that attack buildings. They deal real damage in numbers and die to any air splash instantly, which makes them a burst tool for a base whose anti-air is already dealt with.
What it does
A group of bats appears at the target point and attacks nearby buildings. They are fragile air units, so their lifespan against live anti-air is measured in seconds, and their output against a base whose air defences are down is substantial.
How it is used
- After the anti-air is gone, as a finisher on the remaining buildings.
- On a specific compartment where a lot of buildings sit close together.
- Never as an opener against live Air Defences, which remove the entire swarm.
Because it is a dark spell, the spell housing cost is low, which is what makes it viable as a situational finisher rather than a core plan.

Frequently asked
When should I use the Bat Spell?
After the anti-air on that side of the base is destroyed, as a finisher on the remaining buildings. Used while Air Defences are alive, the whole swarm is removed almost immediately.
Is the Bat Spell good?
Situationally. It is cheap in spell housing and produces real damage against a base whose air defence is already handled, but it contributes almost nothing against live anti-air, so it belongs in a plan rather than in every loadout.
