Commander's Ward

Reach skyward with an open hand and then clasp it shut, sending arcane energy to your allies. Up to 5 creatures you can see gain 6 (1d6 + 3) temporary hit points. These hit points cannot revive a character who has 0 HP, but do act as a barrier before further incoming damage forces failed death saves. 

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, number of affected creatures doubles and temporary hit points bestowed increases by 4 (1d6 + 1) for each slot level above 2nd.
