In particular, his most vulnerable areas, like his eyes, nose and mouth were the most prone to this scalding. Thankfully, Alex raised his hand to protect his nose and mouth before it managed to reach them, but his eyes were completely open to it, and his eyelids offered little to no protection.
As one of the few areas of his body where his armour offered no protection, this was quite a devastating result for Alex.
It left him temporarily blind. If not for his spatial perception, he would be completely unable to detect any of the Lux's incoming movements.
The Lux didn't disappoint.
It appeared in front of him in nearly an instant, with its speed far outshining Alex's own. Alex barely managed to raise his sword in time to block the downward strike it had prepared for him, and the sheer force of the impact drove his feet a few metres deep into the ground, digging an impromptu hole that sucked the both of them into.
