Dhuumfire Reaper
I ditched the 50% shroud crit for Dhuumfire even with a power build, the extra damage of having 3-4 stacks of burning is nice considering you already get 50% from DD and 20% from fury

Yeah, Dhuumfire is great with Reaper’s Shroud. It’s only with Death Shroud that it’s terrible. The increased attack speed and cleave on RS1 make a huge difference.
I tried different builds and while I still have to test with a proper Sinister gear I think the benefit of having a few stacks of burning does not compensate the loss while using them. Specifically if you are condition you are using a Scepter or a Staff, and entering Shroud prevents you from applying more condition of those weapons, on the contrary if you are a power user a few stacks of Burning does not compensate the Malice you used instead of another stat or the +50% crit chance you lost due to Dhuumfire instead of Death Perception.
So… meh
you lose 0% crit chance in a power build by picking Dhuumfire (30% base crit chance with a mix of valk + zerk or valk + cele gear, 50% crit chance from decimate defences and 20% crit chance from fury is already 100% crit chance). So every tick burning is additional dps.
You can make Dhuumfire work with RS, but I personally find auto-attacking to be the least effective use of my time. Traits like Reaper’s Might and Dhuumfire reward RS/DS auto-attack so that it’s used even in cases where auto-attacking might not be the best course of action. I ditched them both because they were building bad habits D=
