Furnace Clash RoyaleThe Furnace is a building card available from the Spell Valley. Its lifetime is 50 seconds with a spawn speed of 10 seconds. The cost for the Furnace is 5 Elixir and its main purpose is to bring out the Fire Spirits. It does that every 10 seconds. It starts with 700 hitpoints and is upgraded up to 1792 hitpoints. Since it is a building card, it can be used as a distraction of the opponent’s troops. The Furnace is fragile to the Fireball and the Rocket, but also can be easily destroyed by the Skeleton Army or other group troops. Clash Royale says: “The Furnace spawns two Fire Spirits at a time. It also makes great brick-oven pancakes.”
