You touch a creature and grant it a measure of protection from losing concentration. The first time the target would drop concentration without becoming incapacitated, they do not, and the spell ends.
If the spell is still in effect when the target is subjected to an effect that would apply the incapacitated condition without reducing the targets hit points to 0, the target gains advantage on any saves vs that effect, and the spell ends.
At Higher Levels.
When you cast this spell using a spell slot of 5th level or higher, you can target one additional creature for each slot level above 4th.
