Mindmeld

The creature's scream reverberated across just as it fell out of Lex's body once again. But this time, that was not all. The creature started writing on the ground like a poisoned insect. It used its own wings to beat its own body while its eight legs curled up and dug into its own flesh.

Lex was not able to take advantage of the situation immediately, as he himself was recovering from his sudden weakness and fatigue. Fortunately, he had only recalled that meeting for a moment instead of dwelling on it, or he might have once again succumbed to just the memory of it.

When he came to, he saw that the creature he had been unable to harm at all lay on the ground covered in its own blood, though it wasn't dead yet.

Lex had been forcibly brought out of his Berserk state by the mere memory of that meeting, which is why he retained the sense to not rush over and attack immediately. But that did not mean he gave up.
