Hi.

Runes are useful.

Materies are equally useful.

They are good i suppose.

Pretty ****ty but w/e.

Ok, so what you're going to want to do on Diana is use your q spell then your r every time you want to use it for damage but if you want to kill and they are escaping from you, id suggest you use it twice. Try to also use your e at its max range so they are cc'ed for the longest as the animation does take time if they are further away.
