So I was playing the index when suddenly this happened? I don't think the mimics can cast abilities but i was trapped in the Xaku roots and could not get out. transferrence didn't work, none of my abilities worked, /unstuck just bumped me up a bit, it was all very weird. The ability also never ended, I was stuck like that for the rest of the index. I didn't get afk locked from rewards though, so that's a plus. all in all just a very weird bug.

The mimics can rarely cast abilities. I've seen them place down wisp motes at times

I got killed by a mimic using lavos’ 1st ability, broke shields and toxin got my health
