Mantis Petra

Behaviour and Tactics
They hover just outside of The Knight's melee reach. They fling wind-scythes at the player that arc down, slow at the apex, then come back up.

If possible, try to get slightly above them to lure them close and hit them with a Nail Art or Spell before they hover away again. Alternatively, using Howling Wraiths/Abyss Shriek or Grubberfly's Elegy will close the distance.

They often show up in groups with another Petra or a Mantis Traitor. Get rid of them first, as their aerial attacks make fighting ground-based enemies aggravating.
