Mage/Dark Wizard Pure E/t Build, And A Challenge

If you've hung around class builders / made class builds you probably know that ETW kinda is sad compared to other elemental tris in terms of not being able to tank shots. But it is very gamer.

But also, consider the following:

Spoiler: The build

https://wynnbuilder.github.io/#4_06W07Y0dK0Ty0uA0qo0ON0Ji0Fq1w1r-E-i-i1g00001000CO
WynnBuilder build:
> Brainwash
> Cardiac Arrest
> Stalactite
> Ornate Shadow Cloud
> Agave
> Unspeakable
> Diamond Static Bracelet
> Contrast
> Event Horizon [f6f6]

Looks kinda OK. Except... its a E/T bielemental build.
No intelligence and no defensive skillpoint. But it can nopot LI (no recording :( I will try to add one but it may take... a few attempts for me to reproduce.)

The challenge is to come up with good builds (and good skills) and solo LI with any Earth/Thunder only build.
No potions / consumables of any kind allowed of course (though treebeard will say warrior should get speed surges.)

Spoiler: Honorable mention

ETA spellspam warrior, with 2 nopot solos behind it:
(switch to atlas + bottled thunderstorm for cybel, death metal, yahyabot)
