Mage/Dark Wizard Help Heavy Mage Builds?

I was looking for a tanky mage build that I can use to not die, and I came up with this:
https://wynndata.tk/s/dxnhtp

Pros:
-Good elemental defences
-20k health
-7k regen per minute
-damages are still respectable
-does not require LI or mythics (requires CLS and Hive)
-dual wield with Phoenix Wing for better health & regen: https://wynndata.tk/s/gqwzb9
-possibly even tri-wield with cascade for more walk speed

Cons:
-negative walk speed
-the dps is still on the low side, only around 2.7k
-spells are a little more costly than I like
-negative poison, whatever that does



Are there any other tanky builds for mages that do a better job of being good? (Preferably without LI or mythics)

Statue can also be taken out for Leadlights for better walkspeed and dmg: https://wynndata.tk/s/50rbht

Also my first build so yay

 

Cons: absolutely no mana sustain
Given you are still making a build for the first time I wont just give you the best build i can make but rather give a few ideas to go off of. Firstly hp regen on mage is absolutely meaningless. Secondly negative poison does nothing. Thirdly mana should be more important than defenses and damages 99% of the time. Shoot for 7mana regen or 9 mana steal at LEAST ideally more.
