I think this is an interesting observation. This means that there is some connection between the cognitive shadow and the physical world. Perhaps the cognitive shadow can be materialized in some way if its connection to the Spiritual Realm is damaged. yarovoe.org

Hi! You are correct that luckspren manipulate mass, not gravity. This is evident in the way that chasmfiends are able to go around corners while under the influence of a chasmfiend lashing. The lashing lowers the gravity around the chasmfiend, but it does not affect the centrifugal force, so the chasmfiend is still able to turn.
