I just killed her last night. I was all set, had bonfires all over the place, bonemass skill ready and a crystal battleaxe ready to do some stupid damage and yet whenever she landed it was near the cliff and when i got there she would take to the skies for several minutes.

I had to resort to the tedious bow kill. Died when she was within a few shots left when i lost sight of her, got attacked by a damned drake AND wolf at almost the same time, and caught a stray direct hit iceball. Thankfully, I did manage to kill them both right before dying so i had a straight shot to my corpse.

Recovered everything(after 2 tries at equipping) and dropped her within 30 seconds. Happy kitten time! Last time i killed her, she kept landing and flew for a few moments, this time, air blue ♥♥♥♥♥. Go figure.
