You know the furnace spawns 2 firespirits per 10 seconds, and it lives 50 seconds. 50 : 10 = 5, 5x2 = 10 firespirits.

Assuming it is left alone and the opponent left the towers to deal with them, the second firespirit most of the time reaches the tower. 5 firespirits damage. A firespirit from a furnace does ~300 damage. 5x300 = 1500 damage. -
