As gods, Authority is the most important aspect of their power. It determines the power of divine spells and the total amount of divine energy they can have to use those divine spells.
The next important thing is divine energy. Divine Energy is needed to cast spells, use divine abilities, and it is also their hit point. Their divine bodies will crumble if they run out of divine energy.
The third most important aspect of power is domain, followed by divinity. They don't have to worry about domain yet, as they don't have it and can't use it yet. But divinity is an ever-present need.
They need divinity to increase the power of their divine bodies. It is only with divinity that they can increase their strength, speed, and endurance.
