Storm Rain is a skill i've wanted to play around for a while so this league i tried poison and found that it works pretty well. I bricked my previous poison spark for this and single target feels better due to ballista totems. But overall it uses voltaxic rift as its core item and skin of the lords to get elemental overload.
Theres a interaction but im not sure if this is just me being high all the time but storm rain when used with ballista totems seems to have reduced aoe which makes single target overlapping VERY easy, and on some bosses will melt them. https://youtu.be/hYXSlim_UHY
Right now i only optimized for dps since I'm not playing as much and havent played this build much at all after putting some ideas together. The damage sits around 37 - 45m dps on guardian/pinnacle bosses depending on overlaps but i think 25 is a good estimate.
