Most hitboxes found by combination of elemental, adaptation and bounce based elimination and are possibly (but unlikely to be) wrong. A second hitbox that caused bouncing other than the wings could not be found meaning the second hitbox is currently unknown. It may be a core or a red herring deal.
Hitbox identities are not fully confirmed nor are the rules that dictate which set its using. Likely the first pair for phase one and the second pair for phase two.
Musou variant for the event quests only. Repel may be lower than the expected 100,000 due to its relative difficult to the slay.
No datamined information on defense rate or health pool.
Leg hitboxes are not confirmed due to raw values not matching mainline and elemental being identical on both legs.
