How to do Elesis Z Loop?

Does anyone have any tips on how to make this Z Loop on Elesis? I would appreciate any tips.
I have watched a video about it but I don't have any idea how I can do that fast.

you mean otto shot? It's been around since forever. It's basically Down then Z with a very short interval, like literally after pressing Down you need to press Z immediately. Once you get the hang of it, you can add forward button as well. Only works on platforms. Just practice and you'll master it too. Easiest to do this is with Elesis 2nd Job Spearman.
