#1 - 2012/12/17 10:29:00 PMI keep reading about this feature, unfortunately, I came to the game after it was removed. It sounds really interesting and cool, and I wish that, once I got better gear good enough for higher MPs , I could be able to experience it :(
Can't invulnerable monsters return in MP5?Source
#13 - 2012/12/18 12:52:00 AMWe don’t have any current plans for the Invulnerable affix to rear its head and return. We felt it was a frustrating affix for many players, and that it was out of line with the other affixes, which is why we removed it. In a similar way, we feel that the Reflects Damage affix isn’t quite where we want it to be, which is why we’re looking intomaking some adjustments to the mechanics of how it works, as well as fixing a related bug.
