Rogue Fightclass - Riposte

[drscience 0]

Hello, fairly new to this bot and I'm trying to make a rogue fightclass. I've gotten everything else to work fairly well but I'm very unsure how to make Riposte work for rogues. Currently I have it as the highest priority (at the very top) and the only condition is that the character has 10 energy. 

Obviously I'm doing something wrong because Riposte is only available to the character after he parries an attack. Does anyone know of a way to implement this into a fight class?

Thanks for any help!
