Something I need a more complete explanation on: Chaos weapons and the -/+ affinity. The info from the smith clarified that overcoming the virus converts it all to positive, yes. But what about before then? All he said was that it had both. I'm assuming that it's a chance for - or + affiinity. Can anyone confirm?
