I've put together a quite well rounded Lightning Tendrils build, got some passable defenses and regeneration as well as pretty acceptable damage with 2x6 links (Tendrils + Orb of Storms).
I've put in 60% more multiplier in the general config which is a pretty conservative estimate on what the damage will be in this league.
With the removal of the Orb of Storms internal CD and the sick buff to the main skill I think this can work out quite well.
The gear is not terribly expensive (other than 6L) and playtested the concept it zooms pretty hard on lightning warp as a movement skill.
Lightning Tendrils is mechanically not the best skill in the books to be fair but it has instant damage output and paired with Orb of Storms it might have pretty good single target.
Inpulsa helps with clear, though later maybe swapping to Incandescent Heart for a more defensive option, if it's somehow possible to get enough Chaos Res.
As a rare ring + Life on Spell Hit is probably very good defensively as well since 10 casts a second + Orb of Storms is a lot of instant heal.
This is most defintely not the final version since half of the gear is just some generic rares with cast speed/res/life. + Level Gems is pretty insane for Lightning Tendrils so getting this on an amulet might boost this to very good levels.
