How does helmet of horseman exactly work?

    • How does helmet of horseman exactly work?

      Do I need to constantly be wearing while the cavalry is being made for its time to be shortened? Or can I wear it just at the time I queue the production of cavalry to reduce the time and once the production is underway just swap to the regeneration helmet? By the way, does helmet of horseman work if the hero is dead?
    • You need to wear it when you queue after that you can swap. And it works only if hero is alive.
      Pleased to meet you
      Hope you guess my name
      But what's puzzling you
      Is the nature of my game
