Thanks, yeah it’s not easy to farm but useful affixes drop a lot like Infernal/of Alacrity which I used till I get the ‘‘of Wildfire’’ suffix. DPS difference between those two is 8-9k.
2H FS is weaker than most other AA and even with an MI that mods it, still hits weak. And you used Infernal Brimstone with it. It’s a cool weapon, but it has low base damage and no flat fire damage. Combine with low WD FS, means no leech. I did try that with a Shieldbreaker and RF and provided a feedback which came into life; now it has phys>fire conversion but the sustain problem is still there. Though thanks to conversion, procs hits more so damage&clear speed got improved.
