Low effort run. Darksight is the real MVP. The playstyle I showcase also yields somewhat the same results in Chaos Gloom, just that you need to play slightly more defensively in Chaos due to legs dealing more damage.
Strat : Staying in Darksight is the name of the game for me in this fight, but in order to ensure survivability during insanity, Shadow veil, darkflare and trickblade [mobbing ver.] are devoted as a defensive skill to get out of sanity faster. Shadow assault is used to dodge anything that I think would kill me. Overall positioning is more to the middle so I can react to legs.
