You should also have Athena's Blessing for unlimited magic. Now use Rage of the Gods with the Blade of Artemis. Eventually the clones will come out with the Blade of Artemis. Don't forget to transfer health to your family if they have half of there life left.
The clones will come more and more often, if needed use the Army of Hades to take care of some of them. Soon the house will fall apart and you will be on a platform that you can fall off of. First the clones are pretty weak, if your blades are at level five, use the Square, hold Square move to clear them. This fight takes a long time so don't get impatient.
You can give health back to the family if you get close to them and hit circle.
Soon several Kratos clones will come out and attack the wife and child so you have to protect them. You will be at the temple where Kratos killed his wife and child. After beating the first part of the fight with Ares, you are sent to another demension.
