Playing as a druid, I was fixated a few times, and most of the time as a tank, I was in Celestial Avatar. When it comes time to break Samarog when he leaps on me (whilst I’m in CA), I am able to use skills with no cast time (such as the skills which come with Stone spirit/Sun spirit skills) as well as my pet’s skills. I haven’t used any shouts as of yet to test if I can break out of stun (“Protect Me!”) but I would assume they’d work, as some don’t have cast times.
EDIT: To clarify, I wasn’t able to use any weapon skills, merely utility skills which don’t require a cast time.
Thought I’d let the devs know.
We’re trapped in the belly of this horrible machine and the machine is bleeding to death.
