Borrow Concentration

By forming a momentary telepathic connection with an ally, you pass off the mental burden of persistent magic. You target a friendly Humanoid you can see within range. As part of casting this spell, you also cast a prepared spell of 3rd level or lower that requires concentration. The target maintains concentration on the spell instead of you. This spell ends if you cast it again, if the target is ever more than 30 feet from you, or if the spell the target is concentrating on ends.
At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, you can cast a prepared spell of one level lower than the slot you use for borrow concentration.
