This variant of Owlbrow is much harder than the original, it has over 15 times the health of its predecessor, has longer range than a lot of ranged attackers, and over double the attack power. Additionally, it can knockback and slow your cats. This enemy can be a pain, particularly in Elite Corps, where it will interfere with your efforts to kill the mighty Mega Cat.
Decent meatshielding will be needed to stall this owl while a stack of ranged cats does work against its massive health. Anti-floating cats with good range like Kotatsu Cat, Nurse Cat, or Sodom can effectively control it.
