Invulnerable Ranger Pet?
When a ranger calls their pet to revive them, it will revive the pet should it be downed. If this is the case the pet will gain ~3 seconds of invulnerable from being freshly ressed, that’s really the only way it could have done it, outside of an unlikely bug.
Signet of Stone – Pet gains 6 seconds of Invulnerability
Bears – Defy Pain
Bears also have a trait that give them stability if you CC them. It may or may not be a bug related to that trait. I wouldnt know as i havent run that trait in ages.
