When the object hit the primordial energy boundary, it was fascinating to see that, instead of bouncing off like elemental forces do, this physical object hit the boundary and pushed some of its force through it.
Although it did not fully transmit the impact, it was enough to knock Kael forward and disrupt his concentration on the stoneworking.
Kael stumbled, caught himself, and turned.
"What the fuck...?!"
Rex was already thinking about what that meant. Physical objects worked differently from energy-based attacks.
The telekinesis directing the boulder was system-granted, but the boulder itself was just stone, and the stone's mass and momentum existed independent of his system. The boundary deflected the telekinetic direction partially but couldn't prevent the physical object from carrying momentum forward on its own.
