How this ranking works
Each boss is scored on five factors:
Damage output β how hard their hits land
Attack pattern complexity. how many moves they have, how readable
Parry difficulty. how tight the parry windows are
Resource demand β how much ammo/healing the fight consumes
Insanity scaling, how punishing they become on the hardest difficulty
The list goes from hardest (#1) to easiest (#8). Order matters: knowing what's coming lets you save resources for the right fights.
