Clan Castle Troops: Donations, Luring and Defending
Mechanics
Updated: 18 September 2026 · By the Goblins Farm team
The Clan Castle is the only building that puts an active, mobile opponent on the field. On offence it is free reinforcement from your clanmates. On defence it is the single most disruptive thing in a base. Handling it, in both directions, separates players who win attacks from players who nearly win attacks.
Donations, and why they matter more than they look
Members request troops in clan chat and other members fill the request. The donor pays nothing meaningful and gains clan XP and donation credit; the receiver gets troops they may not even have unlocked, for free.
For a new player this is enormous. A Town Hall 5 player in a good clan can carry a Dragon into every attack. It is the fastest legitimate power boost in the game, and it costs nothing but being in a clan that donates.
- Ask specifically. Type what you want and why. "Any troops" gets you whatever someone had spare, which is usually the cheapest thing they had spare.
- Donate back. Most clans track ratios, and the clans worth being in remove people who only take. Donating is also how you get clan XP.
- Keep a separate defensive request. The troops you want defending your base are not the ones you want attacking with, and swapping between them is a normal part of play.
The defensive Clan Castle
When an attacker's troops come within the Castle's radius, the garrison deploys and immediately goes hunting. It does not defend a position; it chases. A single strong defensive Castle troop can eat an entire wave of fragile attackers before it dies.
What makes it so disruptive is that the radius is generous and the trigger is invisible until it fires. Attackers who deploy their main army along a side, expecting a clean run, frequently discover the Castle mid-attack, at which point their army is committed and scattered and the Castle is already among them.
What to put in your own Castle, in general terms: something with high hitpoints that survives long enough to matter, or something with splash damage that punishes massed cheap troops. What not to put in it: anything fragile, and anything that dies to a single spell. Clans usually have a house preference; ask.
Luring: the routine that wins attacks
The counter to a defensive Castle is always the same four-step routine, and it should become automatic:
- Find the radius.Drop a single cheap troop near the edge of the base, one tile at a time, until the Castle fires. One Barbarian is enough. This costs you almost nothing and tells you everything.
- Pull them out.Once the garrison is out and chasing, drop another cheap troop far from the base, in open ground or at a corner. Defending troops chase, so they will come to it.
- Kill them there.Away from the base, away from the defences, surround them with cheap troops or drop a spell on the clump. Killing a Castle in open ground costs a fraction of what killing it inside the base costs.
- Then attack.Only now do you deploy the army you actually planned. The base is now passive, apart from heroes.
Skipping the lure to save ninety seconds is the most common self-inflicted defeat in the game. The lure is not optional; it is part of the attack.
Clan Castle in war
In Clan Wars the Castle matters more than anywhere else, because war bases are designed around it. A war Castle is typically filled with the strongest defensive troops the clan can donate, and its radius is deliberately positioned so that it covers the approaches an attacker would naturally take.
Two war-specific habits:
- Scout the Castle before planning. The war map shows whether a Castle is filled. Plan the lure before you plan the attack, not after.
- Fill your own, early. An empty war Castle on defence is a free star for the enemy. Request as soon as war starts, not five minutes before battle day ends.

Frequently asked
How do I lure Clan Castle troops?
Drop one cheap troop near the base edge to find the Castle's trigger radius, then, once the garrison deploys, drop another cheap troop well away from the base. Defending troops chase, so they will follow it into open ground where you can kill them cheaply before starting your real attack.
What is the best troop to put in a defensive Clan Castle?
Something durable enough to survive a lure attempt, or something with splash damage that punishes the clumps of cheap troops attackers use to bait it. Fragile single-target troops die instantly and give the attacker a free run. Most clans have a preferred defensive donation, so ask before guessing.
Do Clan Castle troops chase attackers?
Yes, aggressively and across the entire map. That is precisely why luring works: you can pull the garrison far from the base's defences and kill it somewhere it gets no support.
