[@Silver Carrot] Post is up. No worries on the length of the post, a lot of arena posts are literally;  

"So-and-so swung their blade low toward the opponent's leg from right to left with their left and rear hand as they stepped into range with their right leg, attempting to cut them off low while aiming with the reverse gripped dagger in their right hand to strike from their right shoulder forward and down into the opponent's potentially now exposed neck assuming they crouched and parried low to stop the initial strike," 

That is a totally valid and legitimate post in this format. Less words then an average paragraph, but totally explains the character's position and their intended action.
