(B)(C) Shield of Faith - V,S,M

A shimmering field surrounds a creature of your choice within 60 ft, granting it a +2 bonus to AC for 10 minutes.

You can expend a use of your Channel Divinity to cast Shield of Faith rather than expending a spell slot. When you cast this way the spell doesn’t require Concentration and last for 1 minute. Ends if you cast the spell again, have the Incapacitated condition, or die.
