Robber Weasel or the Walker of Illusions from Lies of P

Robber Weasel attacks so fucking fast and she dodges back so unbelievably far and begins to lob stabbing projectiles at you despite her moveset being purely strike based

Walker of Illusions is so goddamn weird like she attacks so fast, she backsteps alot during her fight, SHE CAN SPAWN A CLONE, and she is incredibly hard to stagger to even get hits off on. Even if you sidestep (which makes the fight a bit easier) she will still send yo ass back to the stargazer. Not only that, she’s not even an optional boss so you gotta go through her to even open the door to proceed on
