How do you set attacks to consume stamina?

Ive been trying to make an epic fight / souls like modpack myself for a while and the one thing ive been missing is attacks consuming stamina. I was looking through your modpack and it really gave me inspiration to start again but with the same issue. Is it maybe possible to learn how you guys implemented it?

I think you can implement it in the epic fight file in your world when made

Look for anything to do with stamina, I looked around once in epic fight so that's all I remember
