Furnace - Clash Royale
The Furnace card is unlocked from the Spell Valley (Arena 5). It is a moderate hitpoint building that spawns a pair of Fire Spirits every 10 seconds. A Furnace card costs 4 Elixir to deploy. It appears to be a cast-iron steam train furnace with a bubbling cauldron of Elixir on top of it. It is also covered with various other props, including a ladder on the side of it, and a pile of firewood on the other.
