Mage/Dark Wizard Trying To Solo Li, Problems With Build ?

so I'm lvl 105, I just got a flying build for lootruns and buying mythic doesn't scares me (maybe 10stx is my max).
I was using a judas build (can't send links) 7mr, 14khp, 16k meteor, with a the nothing and a nepta for rainbow damages, but I got one-shot (full hp) by the robob's 4th phase charge.
Do anyone have a solution against this ? any advice or tanky enough build to survive this shit ?
build : ornate shadow cowl / anima infused cuirass / cinderchain / memento
moon pool circlet / yang / vindicator (because) / kernel

 

i think ur main problem is ehp, i use this build (these are peaceful rest build and have li items)

WynnBuilder build:
> Albacore
> Starglass
> Adrenaline
> Capricorn
> Intensity
> Yang
> Dragon's Eye Bracelet
> Diamond Hydro Necklace
> Peaceful Rest [f6f6f6]

i made this the other day i think its decent but its a tome build and might have mana problems

WynnBuilder build:
> Albacore
> Time Rift
> Adrenaline
> Capricorn
> Yang
> Yang
> Dragon's Eye Bracelet
> Diamond Hydro Necklace

if you dont have another class that can do li i think just try and replace diamond hydro with royal stormy and yang with moon pool, youll need 2 tomes for the 2nd build then
