Weir

You place a silvery warding mist on a creature, giving it protection against harmful magic. One creature that you can touch, gains 2d8 temporary hit points. While a creature still has these temporary hit points, they have resistance to certain type of damage chosen during the casting of the spell. You must maintain contact with the creature for the entire casting time or the spell fails, the material components are not consumed and you lose the spell slot. 

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the amount of temporary hit points increases by 1d8 for each two spell slots above 2nd and it requires ten additional silver pieces.
