Poise damage on great axe

How would you go about optimising poise damage on a great axe, I’ve got a +24 heavy affinity great axe, I’m not the most adept when I comes to optimising builds usually just go with what I think looks cool, but I want to make something that will absolutely obliterate and enemies poise. How would you achieve this with this great axe in particular or are there any other axes that do a better job. My only requirement is it has to be an axe preferably a cool looking one
