27 Wiz just got Velks Robe (625 dmg click) - Advice?

[baue1446]

So I cannot use it for another 13 levels. I was hoping for some advice on how best to use this thing when I am able to click it. At this stage Im just duoing with a friend and Quadding when hes not online.

If anyone has advice on using it to solo with or even duo with it. Locations.. Strats.. stuff like that. With a 15 sec cast time I am just not sure how best to use it. Plus this is my first wizard and I barely know how to quad let alone take advantage of this type of item. Any advice would be most welcome
