Raider,EK,Poets,phys to elem ; need help with my build ! [video inside]

Im working on a Raider EK poet's pen with full elemental conversion, and Im kinda lost with the scaling process.Ive finished the levelling phase to maps, and Im showing you the concept of the build :Moving with one poets in main hand (bodyswap in this case, could be lightning warp) and procing EK upon arrival, woofing the screen.


Im using random levelling uniques, a tabula, and some crappy res gear.

Im trying to figure how to scale EK damage to be viable at speedfarming delirium (I dont think Sirius is at hand) and emphasis on reaching m a x i m u m attack breakdown dualwielding poet's so my tree is focused on : grabbing all the frenzies/attack rate, then projectile piercing, then life, then damage scaling, then jewel sockets.

What jewels?
Keep that tree?
Rares to targets?
Crafting?

Could you help me with this? Maybe Im just dreaming of a non viable thing aswell since Im not very aware of all the spellcasters possibilities.

Cheers loves!
