The entire magic formation was a powerful gravity spell used to pin the five frogs down.
Nightwing aimed for the main body and used his magic to attack the very soul.
The other five frogs were struggling and squirming as their souls were attacked and devoured by the demonic darkness. Bar-Mammon created a soul and physical form that had Unholy energy. It was a form that was pseudo-Holy and could resist holy energy. But Unholy had a great weakness to darkness.
And the attacks pierced through the frogs. Finally, the bloody blades began to drink.
The five frogs squirmed, but the gravity magic heightened their weakened state.
Bar-Mammon's main body did its best to resist. But he had divided his body, and he could not fight back against Nightwing's singularity form that harnessed a grand amount of energy.
