Mage/Dark Wizard Help Corrupter of Worlds Build

So it's the first time I'm doing CoW and I don't know if it's anything for me to worry about. Anyways, here's my build. Please say it's good or not for a (currently) lvl 68 mage. Tell me if there are any improvements I need to make. Thanks.

I mean my build wasn’t the best, but I still beat it easy with scroll of nythiar, bobs battle chestplate, dragons eye, rest as morph

WynnBuilder build:
> Helmet of Legends
> Bob's Battle Chestplate
> Morph-Iron
> Morph-Gold
> Morph-Topaz
> Morph-Emerald
> Dragon's Eye Bracelet
> Morph-Ruby
> Scroll of Nythiar []

As I said it’s not the best, but it works well and it’s easy to get

 

Would recommend bringing mana pots, as messing up my spell chains is what killed me multiple times.
