Shield Artist

This feat is created by Nedrapter for use in his Land of Arda campaigns, and are balanced to the hardcore nature of them. 

• Increase your Strength score by 1, to a maximum of 20.
• When you hit with a one-handed melee weapon and your other hand is holding a shield, you can forgo half of your damage and get a bonus to your AC equal to your Strength modifier, until the start of your next turn.
• At the end of your turn, if you haven't moved during that turn, an adjacent ally gets a +2 bonus to their AC as long as they are within 5 feet of you.
