Poison SRS --- Challenge to improve build

Hi all

I've been playing SadPanda's Poison SRS build (huge thankyou to SadPanda) and gone down some paths. I'm not a good player, so when i get a build where i can kill uber sirus and uber shaper/elder without dying, well, thats something!

For the first time playing POE, i'm challenged to find equipment areas worth improving. i understand damage gets capped because of poison DoT at 35K.

could also use some guidance on PoB regarding how to configure calcs for Summon Raging Spirit

I don't think Mageblood gives me a real advantage here, i'd have to make serious changes to replace the two abyss jewels for 60% chance to poison.

anyway, looking for ideas!
