Self Health Regeneration Troop
This troop will work just like other troops; attacking enemy troops and resources/ buildings. The special ability of this troop will be self regeneration health. This happens when this troop does not get attacked for at least 10 seconds by enemy troops and similarly when this troop is not attacking enemy. However, it can still regenerate while attacking resources/ building. But while attacking or getting attacked by enemy troops it cannot regenerate unless it gets away from enemy troops for 10 seconds (meanwhile it can still attack buildings/ resources in those entire 10 secs and after which it recovers).
