Note: You MUST have an Ares Temple in your city before you may purchase an Ares House.
Strategy
Offensive
A tower surrounded by this type of house will be extra damaging. Destroy the houses or the tower quickly.
Defensive
This house only affects adjacent buildings. Make sure you place them next to defensive towers.
The attack bonus works as a percentage. For example a 10% increase to a Tower that does 1000 damage gives it a bonus 100 damage. But a 10% increase to a Tower that does 100 damage gives it a bonus 10 damage. Maximize the effect of this house by putting it next to high damaging buildings to make them all the more lethal.
