Compelled Showdown

You challenge your foe to clash weapons against you. As a bonus action, you gain a +2 to your strength modifier until your next turn, and may goad your target to use a martial or simple weapon to contest a strength check against yours. If the target does not have one, they fail the check. If they do, they must use their reaction to contest. If they are out of reactions, then they fail the check.

Once the clash resolves, the victor of the strength check may roll one attack against their enemy. When this attack is made, it has advantage, the critical hit is 18-20 on the dice, and an extra 3d10 of the weapons damage is added to the damage roll if the attack hits.
