It isn't actually the turn-in part of the quest but the last quest in the Keristraza chain in Coldarra where you have to line up and take turns shooting the flare gun to get picked, fly around, then land as she gets taken by Malygos. Having to use the quest item perfectly or triggering a long cooldown plus having the quest fail because the npc dumped you on the ground and told you to run (even though you have to be really close to her to get credit). I only did that on two characters and I wanted to hurt someone.
