Updated for Town Hall 18 (October 2026).
The Clan Castle is the building that connects you to a clan. It holds the troops, spells and Siege Machines your clanmates donate, which you can take into an attack or leave inside to defend your base. At Town Hall 18 it goes to level 14, with room for 55 troop spaces, 4 spell spaces and 2 Siege Machines.
What the Clan Castle does
Every village starts with a ruined Clan Castle. Rebuilding it costs 10,000 Elixir, takes no Builder and no time, and lets you join or create a clan (creating one costs 40,000 Gold). Once rebuilt you can move it anywhere, even before clearing the obstacles around it.
It does three jobs:
- Stores reinforcements. Request them in clan chat, and clanmates fill the castle up to its capacity.
- Defends. Troops inside come out when an attacker gets close, as long as the castle is in Guard mode.
- Holds your Treasury, which collects loot from Clan Wars, Clan Games and the Star Bonus.
Requesting and donating reinforcements
You can request once every 10 minutes. The Gold Pass Request Time Reduction perk shortens that by up to 80%, which brings it down to 2 minutes, and Gems skip the wait entirely. Add a message to say what you want, and you can lock the request so clanmates can only send those units.
Donating has a cost since the Clash Anytime update of March 24, 2025. Training is free, but the donor now pays Elixir or Dark Elixir for every unit sent. A Dragon costs the donor 30,000 Elixir; a Hog Rider costs 135 Dark Elixir. You can also pay Gems instead, and the Gold Pass Gem Reinforcements perk drops that to 1 Gem per unit.
How much one clanmate can send per request depends on clan level. At the top clan perk tier a single donor can send up to 40 troops, and since the Town Hall 18 update clans of level 7 and above can donate up to 4 spells.
Filling it yourself with Raid Medals
Raid Medals from Raid Weekends in the Clan Capital let you fill your own castle with no clanmate needed. The units arrive at the highest level your castle allows, even if nobody in your clan has them that high. Troops cost 1 Raid Medal per 2 housing spaces (a Dragon is 10 medals), and each Siege Machine costs 15.
Clan Castle levels and stats
All upgrades cost Elixir (Clan Castle upgrades switched from Gold to Elixir in June 2022). The Lab cap column is the Laboratory level that limits how strong donated troops can be.

The castle is a 3×3 building. Its troops wake up when an enemy unit comes within 13 tiles. Lightning Spells do not damage it, but Earthquake Spells do.
Siege Machines matter most before Town Hall 12. Until you build your own Workshop, a donated siege is the only way to bring one into battle. From level 12 the castle holds two, but you can still only use one per attack.
Defending with Clan Castle troops
A full castle can wreck an attack that ignores it. Defending troops jump over walls, chase attackers across the map once they are out, and pull ground troops with no favorite target off course. Survivors walk back into the castle at full health after the battle, so a good defense can last for many attacks.
- Put the castle near the middle of your base so attackers cannot pull its troops out from the edge with one unit.
- Mix units. Troops leave in order of housing space, smallest first, so a few Archers in front make the attacker wait before the heavy hitters show up.
- Pick defenders that survive a single Poison Spell. Dragons, Lava Hounds and Headhunters are common high-level choices; Headhunters are especially good at shutting down heroes.
- Remember that only troops able to target the attacker come out. Balloons will stay inside against an all-air attack, and if the castle is destroyed first they never appear.
For Legend League and Friendly Challenges, since February 2025 you can pick the defending castle troops directly instead of relying on whatever is inside.
Dealing with enemy Clan Castle troops
Tap the enemy castle while scouting to see whether it holds anything. Then lure: drop one cheap unit (a Hog Rider works well because it hops walls) close enough to wake the troops, pull them away from defenses, and kill them with a Poison Spell or by surrounding them with Archers or Wizards. Skeletons and Bats do not trigger the castle, so do not rely on them as bait.
At high Town Halls the castle is usually too deep in the base to lure from outside. Plan a funnel or a hero walk that reaches it early, and save a Poison for when its troops come out.

Clan Castle FAQ
Clan Castle sleep vs guard: which should I use?
Guard mode lets castle troops defend your village. Sleep mode keeps them inside so they are still there for your next attack. Use Sleep when you have filled the castle for a Clan War or Clan War League hit, and Guard the rest of the time. Troops that survive a defense come back at full health, so Guard does not waste them unless they die.
How long is the Clan Castle request cooldown?
10 minutes for everyone, down to 2 minutes with the top Gold Pass request perk.
What is the max Clan Castle level?
Level 14, unlocked at Town Hall 18 in November 2025.
