Covering Strike

You make a ferocious series of attacks at your enemies, forcing them on the defensive and buying your allies critical seconds needed to slip past them unharmed.
After you initiate this boost, you can make your attacks as normal. In addition to taking normal
melee damage from your blows, a foe you strike
after initiating this maneuver cannot make attacks
of opportunity for 3 rounds. It still threatens its
normal area. A creature can be affected by only
one covering strike per encounter.
