Anyone privy to the current method people are using to stack the 60% damage buff on perdition to get 2-4 stacks and the buff persists? It can even be done to get 20 but I think that is more group related and a bit more in depth. This is the helmet where its designed to "steal" the buff from people in your vicinity if they too wear the helmet but it returns back to you within 10 seconds by design. There is still a way people are able to "steal" the buff, get a x2,x3 or x4 buff and keep it so they can go do tower or whatever.
just an example video of a druid player holding 4 stacks and drawing attention to the bug.
