I did not know where to put this so I'll put it here at "New troop ideas.
Merceneries are not made from any buildings and are not part of other players' armies. Merceneries are neutral soldiers who can be hired by the players to attack someone else's base, or to do some other task. There would be diffrent types of merceneries. Assassin's of Ferri86TKOI could be one of the very powerfull merceneries. Like I said they are neutral soldiers who take tasks from every player in the COC world, not just from one or one clan. When they deploy on the mission you can be 89% sure that they will complete the mission succesfully. Although they would be very powerfull tool for the players to use they would also be the most expensive ones. One mission would cost the players 3 590 000 gold plus the cost of the soldiers (for example Ferri86TKOI's assassins would cost 3 000 000 gold because they are expert at theire work and with them you can be 98 % sure that the mission would be succesfull) plus the mission type (for example air strikes would cost 70 000 gold). And yes, they can only be paid with gold, but if you want them to be better prepared and armed you could add some of your elixir and DE supplies.
I will not put any information because they are not normal soldiers and there would be more of them. The soldiers I leave to the others to create.
What do you think about the idea? :)
