You configure the scrap metal and wiring used as the material components to create a shield generator and then deploy it onto a creature you can see within range. The creature gains temporary hit points equal to 1d6 + your spellcasting ability modifier. Until the spell ends, at the start of each of the target’s turns, it can choose to gain a number of temporary hit points equal to your spellcasting ability modifier.   Each time the target takes damage, you must make a Concentration saving throw, as if you took the damage. On a failure, the spell ends.   When the spell ends, the target loses any remaining temporary hit points from this spell. The shield generator also falls apart into the material components used to create it, and you can reclaim those material components as an action on your turn while you’re within 5 feet of them.
