With control over a three-star Divine Artifact such as the Monument Of Ordinances, Hal was in the best position to manipulate Divine physiology for the benefit of himself and his forces.
Once the Array was completed, there came rays that shot and pierced through every one of the godly forces on the scene except Karmit.
Karmit was excluded because Hal felt it would do better for the Array and the control of the Array if the strongest of the bunch, a General (considerably weak compared to other gods but a General nonetheless) was excluded and did not disrupt the equilibrium.
All the Astral energy that Hal had used to create the Array had come from him but the bolstering that allowed it to pierce and impact the gods was from the Monument. A partnership of sorts.
