Behaviour and Tactics
It floats back and forth passively, dealing contact damage but are otherwise harmless.

As they tend to stay up and out of reach, jumping with Monarch Wings and attacking upwards or using Howling Wraiths or Abyss Shriek is the easiest way to take them down.

One is found floating above the Lake of Unn, floating back and forth peacefully. More can be seen in the background in this area.

Another is found in the Queen's Gardens, just outside the White Lady's place.
