A Rank 2 Transcendent of a higher world…
That's an opponent I wouldn't be able to best even if I opened my Domain of Valor. At best I would be close to the UPL of a Rank 2 Transcendent but for the quality of our skills? I would only be confident with my Energy Control.
Besides, we also don't know whether he's an early, intermediate, or late-stage Rank 2 Transcendent. The difference in UPL between Rank 2 and Rank 3 Transcendent would surely be higher than the difference between Rank 1 and Rank 2 Transcendent.
If he's currently placed at the late stage then even Sofiel would be hard-pressed to fight him. There's also a number of possible higher world methods that he could employ during a battle.
