Boom!
Eren's body crashed on the ground after the vector force acting on his body couldn't maintain his flight. A deep depression in the ground was created as Eren's mana defense reacted in response to his fall.
The mana layer disappeared after the impact because Eren could not control it around himself. As a result, his body was completely exposed to the elements. All while the mirroring effect of Rupen was still active on his body.
Drag.
He was dragged far from his first impact because of the residual force, creating clouds of dust in its wake. He was dragged almost 100 meters away from where he had first crashed onto the ground. Krista, Lambert, and the new guy stood even farther away from him.
Nobody tried to do a follow-up attack on Eren. That's because they were paralyzed by the effects of his soul sense that he had spread forth right after he was hit by Rupen's spell.
"That's… that's a soul sense. This monster is something else indeed."
