Any Class Help Highest Single Dmg Build Possible? (can Be Either Single Melee Or Single Spell)

Hey, I am looking to create a build with the highest single damage possible (both melee and spell dmg). I do not care about max stats items or mythics, this is purely theoretical. If you cannot help, do you know anyone that T could message that has ideas of how this could work? I remember a cata build back in the day that could do 23K+ spin attacks, but idk if that is the highest.

Remember, I am not at all looking for practicality. I am looking for:
Highest single melee dmg build
Highest single spell dmg build
Highest DPS possible

 

Nighthawk, Time Rift, The Crossing, Stardew and Divzer.
Combined with Ambivalence 72k Arrow Storm, sadly doesn't work in game.
But without Ambivalence and with Diamond Static and Diamond Hydro accessories 54k Arrow Storm.

Only 1 durability because everything fucking dies from your alpha male 80k arrow storms: https://wynndata.tk/s/eplab1

 

Are you allowed to incorporate vanish bonus into another assassin spell? If so, I got a build with 77k multi hits, and pretty decent survivability here.

 

Kinda what i was looking for, but i was more looking of the biggest dmg number you can make (not a multi-hit spell like multihit and arrow storm)

 

32k meteor(max 58k) but hp and mana is oof
