Alex waited for another kobold to come at him, and instead of cutting him down, he raised his hand to catch the kobold's crude blade.
Instantly, a sharp pain pulsed in his hand as blood trickled down the caught blade. But when Alex cut him down, anger in his eyes, he felt it again.
Like he was slashing through a liquid object, his blade slowing down on contact and feeling like it was sluggishly pushing through water. And this time, it was accompanied by the same feeling in his hand as the blade phased through it, clattering to the ground before him with almost a dull sound.
He looked at his hand, with the wound on his palm already closing on its own, and couldn't understand how something that looked and sounded so immaterial had caused actual damage.
