If you stagger Moorwing in the very corner before he's phase transitioned, you can basically guareentee how the rest of the fight goes with this rotation. He will scream and be staggered before he can do anything else, then after the 2nd stagger, you want to redirect him to the corner, since otherwise he can fly away. You will sometimes take damage but he should die. This is obviously rng to set up but it's not really an uncommon pattern
