this build merits +1, all looks seriously and with casiopea's burst style, spellvamp-based build is great idea..

Vote up +1

But good build :)

Heyo, I Strongly suggest adding pictures/icons for your items, it breaks up the giant wall of plain white text and makes it more likely people will read all the way through. Here's a link detailing procedures for icon/image embedding:

You might want to include something about incorporating Abyssal Scepter if you dont take Sorc Boots, as the lack of 20 MagPen is extremely noticeable against most enemies.
