I have a 21 wizard and I've been told I should covet this item and I'm having trouble seeing why. It has a 5 second cast time and casts a spell that I only use at this point for finishing off stuff that is at 1 or 2% life. Why should I want this thing?

I can see it being useful to lower level wizards but at my level, it seems pointless. Am I missing something?
