Evolved version
Description
The Furnace is a spawner building that periodically summons Fire Spirits. Each spirit jumps and explodes against enemies or towers, generating constant pressure and light area damage. It can also attract troops that attack buildings, providing defensive value. It is vulnerable to spells and direct attacks, so it needs to survive to justify its cost.
Evolution description
With the evolution, when the Furnace is attacking, the rate at which Fire Spirits appear significantly increases. These can alternate their exit to the sides, generating more pressure and making it harder for the opponent to ignore the building. The longer it remains active, the more offensive and defensive value it can produce.
