A simultaneous assault from two Rank 4 Transcendents! Even if I could boast of being able to contest against them, my chances of defeating both were possibly lower than 50%. It's not an overestimation but it's also without my Chaotic Energy added in as a factor.
With their senses a lot better than Rank 3 Transcendents as well as the influence of their upgraded Domains, there's a high chance they could detect it before I could apply it to them. It'd just be a waste of Chaotic Energy units that I painstakingly stored if I somehow missed. Before using it, I have to be certain that it will affect them.
Besides, given how things were progressing – them getting detected by me and the battle happening at a distance – they finally figured out that I was a threat worthy enough for the two of them to work together to eliminate in the shortest time possible decisively or this Space Vessel of theirs would be turned to dust and inoperable.
