You are able to fill your loot cap from just a single HQ without draining wall HP. Please note that this method will surely result in disabling the player completely as there is no hospital to handle that much injuries. It is only advised to do it on seemingly inactive players.

Prerequisites needed:

• Someone in your alliance to create a rally that you can join
• Have 20 fuel available (10 for the attack itself and 10 to join the rally since it will most likely be against a player – you will get these back)

Common mistakes:

• If you switch to the rally too late the HQ will start burning
• If you switch to the rally too soon you will not kill all troops and you will fail the attack
• If you go back to your HQ instead of joining a rally the target will start burning
• Not timing it perfectly when there are almost no troops (video at bottom)

It gets a bit tricky when there are just few troops inside and you only need to shoot once. There is a split second window where the arrows pointing to the HQ are gone and the troop stops moving. This is exactly when you need to join the rally and you need to time it perfectly. After a few mistakes you get the hang of it:
