Wanted to make sure of something but I'm assuming jet packs would be considered in th 100 shard category? The jetpack itself could only boost the user's jump a bit and, in the case they were already mid air after jumping out of a plane, guide the person's fall and soften the fall a bit.

Also something entirely specific but would these be considered regainable? They're drones that act as light shows through hologram projection but also as a shield and kind of a glider when they're connected to one another.
