CDR build for WIZ

This is a request for a remake of an existing Item.
Explosion Blast does little to no damage in Grs.
It would be nice to have an additional Item for increasing the Damage.
I’m thinking a remake of Dark Mage’s Shade would do the trick.
No one ever uses this Item anyways. I’m a bit bored with always having to channel spells , and would like the ability to create a competitive CDR build for the wizard.
