• Help! My troops died! Are they gone forever?!?!?!? •
Most of the time if a unit is defeated in battle, it will only be injured, and will be ready to go as soon as you start your next battle. Those that have died, however, are not gone, they just need to be resurrected. This can be performed from the Temple’s Graveyard. The only cost for resurrection is gold.
You can reduce the percentage of troops that die with upgrades in the University.
