Armon's Barrier Shield

An imperceptible barrier of magical force protects you and allies.  Choose a maximum number of creatures, that you can see within range, equal to your spellcasting ability modifier. The distance is a 15-foot Emanation originating from you.  The barrier absorbs the attack/damage and dissipates after the initial attack is done.  If it is an AOE (area of effect) spell/attack, you and the warded creatures, have Advantage on the save and take NO damage if you succeed; half as much on a failure.

Until the start of your next turn, only you the caster, receives a +5 bonus to AC, including against the triggering attack.
