Private audience
The nearest troll and human both stopped their fight and attacked Lex with a burning fury, only to be blocked by his invisible barrier. The troll's anger only grew, and it redoubled its efforts, but the human paused after the shock of a failed attempt.
Still, it only took a glance to be able to pick out a flaw in Lex's so-called defense. If the barrier extended from his hand, and he was holding it forward, all he needed to do was attack from a different angle.
It was the deduction of an experienced fighter, but alas, it made no difference, as Lex simply moved one of his hands so that instead of one strengthened barrier, he had two. His plan was simple: he would block as many attacks as he could, and should any get through, he'd just suffer them.
