Sacrifices and Lightning Bolt

Even before the appearance of Tirana, not to mention Thunder Demon, Jade Lady, and Obsidian Armadillo, Adam was pretty exhausted from three battles in a row.

First against Firebreathing Trinadon, then against Iren and Six-Winged Iron Stingray.

Sure, up until Adam finally decided to enter the fight, given the time it took Prago to get there, Adam had managed to regain some strength, moreover Resonance was doing its job, allowing Adam to squeeze the absolute maximum out of his body. 

However, even in such circumstances, Adam could only use his Nexus one more time, First or Second Trait, in this case, it didn't matter. After that, all he would be left with was some Order, after all, he had used his artifact quite a few times already.

Thus, it was quite difficult to make a choice in a few seconds, but... when the end of this period meant inevitable death, Adam's brain was working at its limit.

Step. Step. Step.
