In case it matters, right now I'm using a mix of Omen (ring, pants, deck) and Darkmoor gear (everything else).
If you want to maintain your resist and damage, as well as increase your critical, then I recommend this:
Malistaire hat Malistaire robe Shadowbones level 120 death shoes Either Malistaire wand or one of the pack ones. Grandfather Spider Death athame Rat/Morganthe amulet (though I recommend Rat amulet to make up for block lost with using Shadowbones shoes) Alpha and Omega Ring / Aphrodite ring Omen deck
With this gear set, you are able to have WAY more health than most Death Wizards have at your level, as well as having more damage but keeping around the same resist. The Shadowbones shoes will also let you boost your critical rating and damage up.
You will need to use Jewels to make up for the lost power pip chance and accuracy, however.
