I’ve a similar setup, but am playing around with 3-piece Justicar & using Gaze of Empyrion helm (https://www.grimtools.com/db/items/8131) to boost AoC flat damage (& radius). In Crucible, censure kills all the trash allowing you to focus purely on killing elites / bosses.
I’m also playing around with Light of Empyrion Devo. It’s ok & wish it would proc more often (20% chance on hit by melee attacks) but I think Meteor is the way to go.
As per mad_lee’s advice, definitely change out the components on the weapons to Enchanted Flint to boost flat fire damage. Prismatic Diamond in the helm would help here too whilst also provide damage absorption for those critical moments.
The Helm: is it really a good trade if you lose the Justicar (4) piece proc and +1 Demo ? (genuine question)
The Amulet: good point. I think the flat damage and +1 all skills is better than 10% phys. conv. and better Vindictive Flame.
Devotions could be improved. You should try and get that sailor in place of eel and get rid of point siphons like the chariot (get fiend insted and you got two points to move - with them take sailor for eel and tower for wolverine - plus a decent boost to dps).
Scratch the above. You have 150% attack speed, sir. Fixing that is priority one. Blue Beronath amulet, Revenant, consecrated wrappings, dread skull, jackal.
I didn’t see how to get Revenant, Jackal and the Tower without giving up Meteor. I will try without Wolverine and Giant’s blood (?) tonight. I edited the grimtool link according to all your advice so far.
