Mage/Dark Wizard Help A Certain Gaia Build Help

Haii, recently got myself a gaia but I can't make a good build for it ;-;
I'd appreciate if you guys help me out thanks.

Requirements a.k.a Stuff that I want in the build:
- High melee output.
- No mythic boots except warchief if that even possible.
- Can do LI, or can solo it.
- The above one kinda make it obvious but if not, No LI items whatsoever.
- Can be glassy, if not tanky as hell(at an extent).

Defenses can be easily powdered if necessary and should be able to do LI. Dump extra sp into agility for the most part.
Using warchief https://wynndata.tk/s/mJ2W08.
Swapped CoI to Insulated to make it so the defenses weren't atrocious due to warchief.
Full blown glass cannon https://wynndata.tk/s/SOtdHY.
Speaks for itself. Extremely glassy due to the bad elemental defenses and -ls+-ms. Can it still solo LI? Yes, but it will be considerably harder and you'll actually need heal pots.

 

umm i think 13k with good defs?
also *bump*

 

I guess a good def build would be smth like this: https://wynndata.tk/s/hGixFn
