I travelled to the shrine but averna wasnt on the pillar, i assumed this wouldnt be a problem and hurt her to the point where the blue light effect occured, i then ran away and the quest completed. I have looked up a playthrough on youtube and mine was totally different, averna never ascended, their was no bubble like formation around the pillar and the fireballs never fell. She is just sat at the shrine, never leaving. I have no more quests from her and the void crawler (or whatever it was) doesnt spawn.
Anyone know what i should do??

Thanks :)
