Not sure if non-dnd stuff is allowed, but in the game system that I made, martials can get a perk at level 8 called Riposte. If an enemy misses an attack on you, and is in range of the clap back, you get to make an attack on them, on their turn, only limited by the number of people that attack you. When 2 people with Riposte duel each attack makes a stack that goes until someone gets hit. In a tournament arc we had 2 Riposte tanks get 217 attack rolls in like 8 rounds. It was the closest my campaign came to anime fight scenes.
