Okay guys, let me tell you the truth :
Demon hax stole the weapon stacking bug from PH players and created this thread like he found the bug, but no, it wasnt him. For some reason he is hunting for thanks from the community here, kinda patethic, but whatever. He is just pretending that he is a bug guru of cabal. Now he is just throwing meaningless words at us like it means something (for example epaulet method, skill modification, etc). All of this is fake.
He created a new account for posting here, namely solaris shepard, all this to make you believe that the bug works, but no, he is just making a fool of you with this fake account.
Tldr: someone made the original damage bug public, this demon guy stole it, and posted it here like its his own, and now trolling people with fake account.
