Replace current belt with a Replica Soul Tether -
https://www.pathofexile.com/trade/search/Kalandra/dZ20KrqsJ
* Reason - You have a very large ES regen rate from your ascendancy. But you have no ES to take advantage of it. This belt is a very common item for RF inquisitors due to how much
effective ES it provides (over 800es).
Replace boots with Legacy of Fury -

* Reason - These boots provide a nice damage increase due to Scorch effect and the secondary unique effect provides extra damage for clearing.
Replace current helmet with one of these -
https://www.pathofexile.com/trade/search/Kalandra/48mkVlLT9
* Reason - This will allow you to move your Trap setup to your chest for a 6L and provides an effective 6L in your helm. It will shrink your RF AoE radius but the boots will help make up a bit of that for clearing. That trade link has an empty prefix to craft life on it. Put RF, Ele Focus, Life Tap and Increased AoE in the helm.
Replace your current chest with the same chest but with 3G/2R/1B -
https://www.pathofexile.com/trade/search/Kalandra/B40RlWC8
*Reason - You now have room for a 6L trap setup. Move the Swift Affliction and Burning Damage gems you took from your RF links and put them here. Sell your old chest.
You'll be missing resists now. Replace your 2 rings with life, ele and chaos resists to make up what your missing. Don't be afraid to spend 20-50c on each ring.
There is still a lot of room for improvement but start with these.
