I picked up silvery barbs on Falgrim when he took they get touched feat.<br/><br/>Really though, defensive wise its kinda like shield, it just imposes a disadvantage like state(notice though that with the wording of it, it supercedes advantage...since it works on a success advantage and disadvantage already happened.) Then you give someone advantage on someones next roll.<br/><br/>Certainly a tide turner, but it has two limitations. Line of sight, and distance. So anything that can break L.O.S. will work to mitigate the impact silvery barbs can have. Also any ranged adversary can just out range the spell.
