i dont understand, i use frozen orb attack, and u said just stick with one element and i already have icebolt, cold mastery, and frozen orb maxed, and i need to know what order do i max all those other cold skills, got it?

I would say max ice blast OR glaciel spike and use that as a spammer. It's your preference which one you want to use.

sorry but my english is a bit bad :(
i hope i understand right,you want only attak with orb?so you need only to max ice bolt
you can take fire as an other element
i hope i understand right and could help:(
