Shield of Swings

Prerequisite: Great Weapon or Two-Weapon Combat Style, Level 6

A wild frenzy of attacks serves to bolster your defenses. When you take the Attack action while wielding a two-handed weapon or a one-handed weapon in each hand, you can choose to reduce any damage you deal by 1/2 to gain a +4 shield bonus to AC until the beginning of your next turn. The reduction in damage applies until the beginning of your next turn.
