Ever since Forsuth first shielded me at The Wall I've been jealous of his
ability to shield my summoned wraith 2 minute long ice shield. So I had the idea of why not add an effect similar to that of rejuvenate, where it is more effective at healing when cast on another player. In this case though the ice shield will last longer when cast on another player, up to 120 seconds. It would be a nice incentive for ice shielding other players alongside the (unfortunately broken at the moment) bonus damage points.
