Scoring a solid hit, Ütés' confidence grows, maybe this isn't her final fight after all. Withdrawing her blade in the most painful way that she can come up with on the spur of the moment she pivots once again shifting her weight to her back leg and then lunges forward, sword straight out in front, as she tries to drive the blade into Gasher's heart.
Riposte: When a creature misses you with a melee attack, you can use you reaction and expend one superiority die to make a melee weapon attack against the creature. If you hit you add the superiority die to the attack's damage roll.
Since I'm not 100% sure that 17s a hit, adding the Bardic Inspiration the attack roll.
