I’ve been goofing around with a more spell oriented hybrid Void Knight to see if I could make something viable. I am using both Abyssal Decay and Devouring Orb in this build.
Well the reason I went to the dummy in the first place was because I got killed on a monolith after taking Sequel and it appeared my damage had dropped significantly. Sure enough, this is what I found:
Now according to the tooltip, on my second recast I should be at the same debuff level I was without it and from the 3rd cast on, I should be getting a greater effect. Notice how the damage stays very low and even more odd, just stops completely for awhile.
Here is the same test without Sequel of Decay:
It seems pretty clear the passive is not working as intended at all. It would be a good passive for an auto recast build like I am using if it worked correctly.
