[3.0]Most damage from Essence Drain [HSC]

The most important for damage from all spell is a lvl main skill gem.
Now we can have 28lvl for all spells: 21lvl on main skill gem +3lvl from special items and +4lvl from empower 4lvl in special item linked with main skill

Second place it "more" modifiers from linked support gems and others skills for example new support gem arcane surge

And last "increaced" modifiers from passive tree and items

I chose berserker becouse hi gives me 40% more damage!
At first time I played with staff +3 lvl chaos gems

and I thought that it's the most damage without LL and thougth about change into LL(Low Life can give 30% more damage for spell)
but then Ascendancy Berserker passive War_Bringer will be more useless
Already then I had more damage than anything I found on the forum's Essence Drain bilds
who intersted can look at what was my hero like in Path of Bilding https://pastebin.com/e1Lp6try
In search of the forum I had seen intersting item: skin of the loyal simple robe
then vaaling this we can have +2 to lvl of all socketed gems:
and againe main skill will be 28lvl (21 +2 from armor + 5 from empower(6lvl))
That's when I decided use it and use Righteous Fire for more damage
Now I need to use Rice of the phoenix and purity of fire min 23lvl and have 10% life regen what not to lose hp from RF
