You see I remember her winning the first fight shortly after ROTJ, losing the second one once Luke adjusts to her lightwhip, did well in the third one only due to circumstances with the text making it clear Luke would dominate her extremely quickly (even with only one arm) in martial combat without the circumstances, in the fourth fight I think they clashed then deactivated their weapons and held hands or some stupid shit like that, and in the fifth Luke pushed her off a cliff and decapitated her.
Why is Hidden One so high? He gave Luke trouble wih winds and got one-shotted by a kick from Luke.
Lumiya is > him, in all honesty.
Abeloth should obviously be first, after her it's Sheev, Nyax, Sarasu, Thul and Shimrra who are all comparable. Then it's the likes of Vader, Caedus, Krayt. Then Lumiya and then the Hidden Cvnt.
