Electric Displacement

You and up to 5 willing creatures you can see within range assume a electric form for the duration, appearing as arc of lighning. While in this arc form, a creature has a flying speed of 300 feet and has resistance to damage from nonmagical weapons. The only actions a creature can take in this form are the Dash action or to revert to its normal form. Reverting takes 1 minute, during which time you can't move. 

If a creature is in arc form and flying when the effect ends, the creature descends 60 feet per round for 1 minute until it lands, which it does safely.
