Furnace – Clash of Clans

Furnace spawns Firemites over 60 seconds — these explode on buildings, dealing instant damage plus burning pools of fire.

Furnace damages itself over time. If destroyed early by defenses, remaining Firemites are lost — protect it if possible.

Place Furnace in corners to funnel troops or create chaos in perimeter buildings before your main army advances.

Excellent CC troop — stays at castle spawning Firemites continuously, forcing attackers to deal with burning damage.

If healed, Furnace eventually stops spawning Firemites. Only heal if you need it alive longer for strategic positioning.

Burning pools deal damage over time — great against clustered defenses where fire spreads across multiple buildings.

Unlock Furnace by upgrading Dark Barracks to the required level at this Town Hall.

Prioritize Furnace upgrades when it fits your preferred attack strategy and army composition.

Final upgrade unlocks maximum potential — making this troop viable for high-level raids and clan wars.
