I was actually trying to test if it could be used to trigger sneak attack on rogues as counting as a combatant near the enemy target, but it was so inconsistent as enemies kept moving away from it. That would be one interesting use for a arcane trickster shooting arrows from a distance. Additionally it is supposed to gain additional functions, but it feels under developed.
Pushing targets is ok, but maybe over powered as it allows you to basically have a second action (or was it bonus action?) on a target.
I was hoping since it was floating I could use it to go over non-navigational terrain like water or steep rocks to reach loot boxes or switches, but that didn't work either.
