sadly the guide explaining this got nuked
different sources doesn’t matter alone for stacking, type does, different sources matters to get the highest of same type to apply if it’s non-stackable type, or ex if in multiplayer for stackables
debuffs are kinda the same as RR, there are 3 types
-**% (minus symbol, that’s important)
%reduced target’s something something
N’th reduced (we call it “flat”)
we have ex in your occultist case Vulnerability (2nd node in Curse of Frailty), Wasting (2nd node in Bloody Pox), each respectively reduces OA and DA, but notice the minus symbol
then in ex devotions we have Korvaak with Eye of Korvaak proc, reducing targets OA/DA by 130(flat)
that means you can smack Wasting+Vulnerability ontop of korvaak and reduce targets OA/DA by the combined amount
but, lets say you also have a soldier, with Blindside (flat) and Markovian’s Advantage (flat), or your’re a “poison occultist” so you take Scorpion Devotion with Scorpion Sting (reduces targets DA 150(flat))
that’s combined 4 sources, but of the same type, N’th reduced(flat), hence they don’t stack, highest applies
the highest will still stack with Vulnerability/Wasting because those are stackable types of debuffs - but if you are in multiplayer you can’t put 2x Vulnerability from 2 occultist, because then “same source” matters
%reduced and N’th reduced is not stackable(regardless of source), only highest applies. But you can throw them on to -%(minus symbol) and have as many stackable(from different source), with 1 of each non-stackable(regardless of source)
then look at DR, it says **% Reduced Target’s damage, %reduced being key, no minus symbol, hence it’s not a stackable, you can only have 1, and it will be the highest value that applies,
doesn’t matter if it’s DR, speed, resists or Fumble/Impair, %reduced doesn’t stack on itself
i can tell you right now it’s not gonna be awesome, unless you manually focus on ordering the Yugol blobs around (which would be wasting your player input),
because the blob AI is gonna wonk around, together, whereever, where you don’t need them, to where there is no point in stacking both Yugol and LoE in hoping that blobs take care of the ones LoE didn’t fully reach
