The Odi had taken into account that one or more of the creatures composing the pseudo-Balor could be killed in battle and had given them plenty of options.
The six heads were the first to finish assembling. The final result was a monstrous face with four mouths and twelve eyes arranged in a circle.
Ten of them were brimming with power and emitted a stream of multi-colored mana that closely resembled a Balor's elemental pillar. Except it was much weaker due to both the incomplete powering up and merging of the creatures' mana core.
Ellkas used one of his artifacts, the Void Shield, to take the full power of the mana pillar without interrupting his attack. Phloria's kill had thrown the creature off balance and by using one of its more powerful moves despite its debilitated state, had forced its movements to a halt.
