Weapon Mark

When you make a melee attack with a weapon as part of the Attack action, you mark the target of that attack until the end of your next turn.

You can mark multiple creatures with this feature. Each weapon attack you make as part of the Attack action can mark its target independently. Marking a creature does not end any other marks.

While a creature is marked by you, once per turn when it provokes an opportunity attack from you, you can make that opportunity attack without expending your reaction. You have advantage on that opportunity attack.

Each marked creature can trigger this benefit once on each turn. Each mark ends independently at the end of your next turn after applying it.
