Updated for Town Hall 18 (October 2026).
The Freeze Spell shuts down enemy defenses and defending troops inside a 3.5-tile circle for a few seconds. It unlocks at Town Hall 9 with the level 4 Spell Factory and takes just 1 housing space. The current max is level 8, added for Town Hall 18 in April 2026, which freezes its targets for 6 seconds.
How the Freeze Spell works
The spell freezes everything hostile in its circle at the moment it lands. A frozen defense stops firing, and frozen Clan Castle troops (ground or air) can’t move, attack or heal until the timer runs out. Your own troops keep working the whole time.
Three details trip up new players:
- Only what is inside the circle when it lands gets frozen. An enemy troop that walks in a second later is free to fight.
- A Hidden Tesla that is still hidden can’t be frozen. If it pops up inside the circle while the spell is still active, it is frozen for the rest of the duration.
- Freezing a single-target Inferno Tower also resets its damage ramp, so when it thaws it starts again from the lowest damage.
Freeze Spell levels
Research is done in the Laboratory with Elixir. Costs and times are the standard values before a Gold Pass discount.
| Level | Freeze time | Research cost (Elixir) | Research time | Lab level | Town Hall needed |
|---|---|---|---|---|---|
| 1 | 2.5 s | None | None | None | 9 |
| 2 | 3.0 s | 1,200,000 | 1d | 7 | 9 |
| 3 | 3.5 s | 1,700,000 | 1d 12h | 8 | 10 |
| 4 | 4.0 s | 3,000,000 | 2d | 8 | 10 |
| 5 | 4.5 s | 4,200,000 | 2d 12h | 8 | 10 |
| 6 | 5.0 s | 6,000,000 | 3d 12h | 9 | 11 |
| 7 | 5.5 s | 7,000,000 | 5d | 10 | 12 |
| 8 | 6.0 s | 28,000,000 | 15d 12h | 16 | 18 |
Level 7 arrived in 2018 and level 8 only in April 2026, so Town Halls 12 through 17 all cap at level 7 (5.5 seconds). Each level adds half a second.
How to use the Freeze Spell
Good targets
Save Freezes for the defenses that would wreck your plan in a few seconds:
- Single-target Inferno Towers melting a tank or hero. Freeze beats a Healing Spell here, because the Inferno does nothing for the whole freeze and comes back at its weakest damage.
- Multi-target Infernos, X-Bows and Scattershots chewing through swarms of small troops.
- An Air Defense while Balloons or other air troops close in on it.
- The Town Hall’s weapon. At Town Hall 17 this is the Inferno Artillery, whose splash can wipe out the Super Archers or Super Wizards a Battle Blimp drops beside it.
- Strong Clan Castle troops such as Dragons or Wizards, ideally while they stand next to a defense you also want frozen.
Placement and timing
Drop the Freeze as your troops are about to start hitting the target, not while they are still walking toward it. Six seconds goes fast. Line it up so the circle covers two defenses if they sit close together.
Freeze or Lightning?
Both reset a single-target Inferno. The Lightning Spell only stuns for a split second, so it fits an Inferno that is nearly dead. Freeze is the better pick when the Inferno still has plenty of health and needs to stay quiet. For weak Clan Castle troops, Lightning or Poison is usually the cheaper way to deal with them.
Because Freeze takes 1 space, two spells can reset an Inferno twice. It also fits in any Clan Castle that holds spells, from level 4 up.
How to defend against Freeze Spells
- Build an island: an Inferno Tower, Scattershot or X-Bow walled off with a 2 or 3 tile gap around it, so a Freeze on it can’t also catch a second defense.
- Spread out splash defenses so the attacker needs a separate Freeze for each one, and keep their range inside your Walls so a single tank can’t absorb the hit outside.
- Use Hidden Teslas and a Tornado Trap to slow troops near the frozen defense, so the freeze ends before they reach it.
Recent changes
- June 27, 2022: brewing spells no longer costs Elixir.
- February 2025: the Freeze Spell’s deploy effects were changed, then put back three days later.
- March 2025, “Clash Anytime” update: brewing time removed.
- April 27, 2026, “Sound of Clash” update: level 8 added for Town Hall 18 (6 seconds).
Don’t confuse it with the Ice Block Spell (June 2025), a Dark spell that encases your own troops in protective ice instead of freezing the enemy.
Freeze Spell FAQ
How long does the Freeze Spell last?
From 2.5 seconds at level 1 to 6 seconds at level 8.

Yes. A frozen single-target Inferno Tower restarts its damage ramp from the bottom when the freeze ends.
Can you freeze a Hidden Tesla?
Only once it has been revealed. If it reveals itself inside an active Freeze, it stays frozen until the spell ends.
What is the housing space of the Freeze Spell?
