Doesnt give any cc immunity? Today I was triple petrified, it didnt kill me, but it was damn annoying having it cast on me 3 times in a row, like once per second for 3 seconds. And if I didnt have a healer, id die from it.
Before you CC break out of fossilize, enemy player can cast it again and it will extend the duration. Your character animation will look like he is standing up and going back down again.
Same with NB Agony and I believe Rune Prison as well.
