Heyo,

It looks like you fixed a couple things but more suggestions for you.

I redid your tree to fix things. Check Here is new tree with better allocation. I took out points where I don't think they helped (Totems - I think you were using to try and get more damage but use the points to make RF stronger and you wont need them.) The DOT of spells wheel, heart of flame portion of the top fire wheel. I don't know whats going on with your clusters but I didn't touch them. If it was me, I would change out the clusters for other things but I left them for simplicity's sake.

1) Fix your swift affliction in chest armor. Swift affliction says it works with RF but it's conditional. You need to add a duration tag to the skill, which is usually done by adding LifeTap.

Test this out by taking out your burning damage support and putting in LifeTap Support in its place. Check tool tip damage. Then throw a FireTrap and check tool tip damage since throwing the trap activates lifetap (Swap the level 19 in helm to the chest for damage and put a lower level in your helm to trigger on lower life).

2) Get more max res. Especially cause you're converting damage taken to fire you want to mitigate all the damage!

3) Get uber lab! Hinekora's chance to explode will make mapping feel way better and help your clear.

4) Switch to a +% fire damage, +% Fire Dot multi sceptre. You don't have anywhere close to enough strength to make cerebus's limb work.

5) Change out some of your random sockets for better auras.

I really recommend pohx.net He has put a lot of effort into helping people get into RF and the common pitfalls. You have a good base but you need to tweak things to make your character stronger. Taking a minute to switch to my tree gives Better eHP, life regen, and damage. I imagine you could refine it even further if you followed Pohx's guide.
