The fortune Aurelio kept referring into seemed to be disappearing. A fourth(!) Fighter had entered the fray, and worst of all, he appeared in the same roof as Aurelio. Aurelio's illusion had an effective range of three meters, and anyone inside that range could certainly see through what Aurelio's illusion, in addition to disappearing from sight of others (which would indicate to the others about Aurelio's presence). As this skill took about one quarter of all available area in the rooftop, having anyone else here on the rooftop at all was undesirable. Yet this newcomer was immediately engaged in a battle with another person, potentially causing a chaotic four-way battle.
Hence, Aurelio had two options, to join the fight, or to scram, studying the data he had collected so far. The rational, calm part of him suggested the latter option was more advantageous in the long-run.
Yet he could not miss this chance.
There, just several meters in front of him, stood one of the Fighters dressed in a suit, oblivious to his presence. If he could get a sneak attack in, it would end him in an instant. But he have to do so from a distance, as going melee would break his illusion.
If he had to launch a sure-kill ranged attack, there was only one option. To Aurelio, even this appeared really inappropriate, using a final attack as the first attack he made in this war. Aurelio grabbed his sword, entering battle stance.
"Well, kid. It's good to see you learn a thing or two from me, but isn't this a bit reckless?"
The Dagda asked, a bit amused by Aurelio's decision.
"Watch, Dagda. May this power make you content."
Aurelio replied. He muttered in near-silence, "Final Rapture," and the sword began glowing a bright, golden, even so, his illusion remained unbroken, and the glow was not seen by the others.
Just a moment away, this attack will launch with great speed almost imperceptible by human eye, leaving a trail of golden light, and should everything went as planned the Fighter before him would have his skull pierced.
