Tap the Nomad missions to view their objectives. These missions that have a success rate that relies on the number of Assassins you assign for them, and their individual skills. Tap on the "+" sign to add Assassins for a mission after viewing the briefing. When select one, the "Success Rate" bar will increase. This bar indicates your odds of success. If a mission fails, you will get nothing and your Assassins killed. For the best chance of success, select your recruits according to the required stats. The stronger the recruits, the more in-app currency it will cost. Remember to heal your recruits before sending them out on missions.
