What Does Furnace Do?
Furnace is a building that doesn't attack on its own - instead, it periodically spawns a Fire Spirit for as long as it survives. Each Fire Spirit adds a fresh burst of splash damage against whatever it targets, giving the card ongoing value rather than a one-time payoff.
Because it keeps producing troops over time, ignoring it entirely means facing repeated Fire Spirit attacks, which makes leaving it alone a real cost rather than a safe option.
Where Furnace Fits
It's a defensive, control-oriented building that works well in decks wanting steady chip damage and ongoing pressure without committing more Elixir after the initial placement.
How to Counter Furnace
Since it can't attack directly, ranged troops or spells that hit it from outside a Fire Spirit's range can wear it down safely without ever taking splash damage in return.
