Decrepify and negative IAS Greetings. I finished my military service about a month ago and started playing D2 again now that I have the time to do so. Anyway, 1.13 quickly showed its cheeziness and now I'm sporting around with Grief and a wolfbarb without most of its essence, just the Feral Rage and huge life (though that could really be most of its essence). I'm building a wolfbarb from the scratch but before I proceed any further, I want to take a look at his performance. Since I've never been much of a theorycrafter, could someone explain to me how the negative IAS from Decrepify works? Is there a way to negate it, i.e. wear more IAS than it's needed to hit the 'normal' breakpoint? So far I've understood that it would take off 50% of my effective IAS (EIAS) and then determine my speed. There's another problem: I'm not even sure what my attack speed is since guides say +31% IAS Grief PB hits 5 frames but the wereform calculator says 7 when I use the normal attack that I often hear I should use. Someone has the correct answer? It would help doing the math if I ever find out what formula I should use and where to put the decrepify modifier. The wereform speed calculator shows that no OIAS would boost my Feral Rage's speed ever, nor has it ever boosted it. So, what does Decrepify actually do in wereform attack speed formula?
