PoE Duelist, Smite, Projectile builds

Hey Guys, two or three days ago i got a little bit bored about this league. All day doing 5way carry and earn currency and no goal were to spent it. So i tested about 4 or 5 builds to have some fun Accuracy Stacking Spark Venom Gyre Jug but none of those builds was able to satisfy me. So I looked into poe ninja and tft about some new fun and found and interesting Frost Blades build. FROST BLADES ARMOURSTACKING. I remembered my last Frost Blades build and my feelings were like YES lets build it. So here we are. I would love to have some feedback about how i created the build or even some sugge

POB: This Char is utilizing Oblivion Barb - Synthesized Fancy Foil, the Dexstacking Explody Sword I crafted a couple days ago and was mainly meant to work around it. I am still working on the Character, I was testing around with Replica Farruls that I borrowed from my Flicker Raider, it gives a lot of tankyness. Level is still quite low so 2 extra frenzies could be added. Also +1 or +2 rings, %dex rings or intimidate ring could add lots of damage. This Character is mainly made to make "Oblivion Barb - Synthesized Fancy Foil"

a champion sparker POB:

Good evening PoEBuilds, I have been farming like mad and finally made a champ sparker. I recently got its gear together, but something feels terrible off. The last time I made a spark character was back in Delirium league. I was wondering if anybody could throw me a bone and help and try to figure out what I am doing wrong. For one, I am not exactly sure how to get to 90% all res. I have been trying to get all the non-curse aura effect I can, and even rolled quite a few Brutal restraints trying to get double nodes. The PoB below is for my character. [
