im a noob in this game so plz dont laugh at me cause of mine stupid questions...and question is:can a hero die?
Yes they can die in battle but they will revive on their specific hero base after a preset time period. That time period untill hero revival depends on said heroes level. The higher the level of the hero the longer it will take to revive that hero. You can gem the hero back alive for 10 gems but it's best to just wait.
