Start by building three warehouses and one temple.

Then keep building warehouses and upgrading your base until it is full with them.

Next upgrade your temple to Age of Reclaimmation. After this upgrade all of your warehouses to blessed warehouses.

When you have 3000 suplies build a scarab and do the same for the second scarab.

After this build ten enginers with the first upgrade, if sucsessful you should have a scarab in the first ten minutes.
