So you know how you can put down your barbarian king or archer queen and if it's lvl 5+ you can tap on him again and tap the screen to enable his ability. So for example I put down 5 barbarians when your all out of them you can click in the barbarian list again and click on a certain building and all of the barbarians will go and attack the building you chose it works for all troops. Note: You can only use this 5 times per troop.
Cheers
