I know, The standard question. But i'm feeling i've hit the ceiling on my spark totem build. I was thinking about going cold conversion or crit. But since it's my 3rd league i'm not really sure how these work. Can anyone help me with this? Here's my pob: https://pobb.in/P_5SUcngOSJ0

It's mainly focused for blasting maps, hence i went for big hitting sparks, instead of duration.

Thanks in advance!
