Clash Royale – Furnace


“The Furnace spawns two Fire Spirits at a time. It also makes great brick-oven pancakes.”



  • This card can be found from Arena 5, Spell Valley.
  • This card cost 5 Elixir.
  • The Furnace produces 2 Fire Spirits/10 sec.
  • The Furnace, if left undamaged, produces a total of 10 Fire Spirits.


  • Complements well with other spawn buildings such as the Barbarian Hut and Goblin Hut.
  • The Furnace, is a good counter against other spawn cards even though the Furnace itself is a spawn card.
  • One of the better spawn card for defending.


  • The Fire Spirits produced, deals splash damage. Hence, it is the only spawn card that produces a troop that deals splash damage.
  • Very strong defensively.
  • You will have an elixir profit as it will require 6 Elixir to summon 9 Fire Spirits if they are summoned individually, whereas the Furnace produces 10 Fire Spirits at a cost of 5 Elixir if left undamaged. Hence you will have an elixir profit of 1 and 1 extra Fire Spirit.


  • Fire Spirits produced is quite useless on its own.
  • The Fire Spirits produced can seldom be used for attacking hence it is not versatile.
