To run WSK and not worry about Black Souls, I have my sorc wear TGods belt, Dwarf Star and Ravenfrost. So I’m absorbing lightning, fire and cold at all times. I can pretty much walk up to Black souls and orb them, and there’s just not much to worry about at all - maybe dolls if I get amped, but not too tough if I’m paying attention.
Anyone ever try this? Or do you have ideas on refining this approach? Or, if you think it’s crazy, go ahead and say that, too 
basically my lightning sorc can survive most place, almost everywhere in the game.
Just need to have wisp ring, raven frost, and a phoenix shield.
Wisp ring - lightning absorb 20% is better.
Raven frost - prevent frozen and cold absorb 20%
Phoenix monarch shield - 20 fire absorb, max fire and lightning resistance. the redemption aura is even better. let you absorb health and mana from dead monsters, you wont even need pots anymore. A very good survivability shield i can say.
As for the FCR you need only 117 for lightning sorc. so comes from:
Griffon : 25%
20% lightning Escuta orb : 40%
Mage fist glove : 20%
Arachnid Mesh belt : 20%
2/15 sorc ammy : 15%
Total 120% more than enough.
Wait until you tele into a pack of souls. What absorb they say as you lag out one shot die
