What’s the Deal with These Mercenaries?
Heroes and Castles 2 Guide
Mercenaries are optional troops that can be purchased in lieu of your crystal completion reward. They appear as optional back up if you lose the same wave twice. The mercenaries do get better and better the more times you lose. If you lose a mission 5 times then you should start getting some super strong friends-for-hire.
