Sekiro: Malevolence - Shigekichi of the Red Guard (DB)

The Frail Blaze Wax used in the video blocks burn buildup and chip damage from deflecting fire attacks. I believe you can unlock the Salvage Shop option for it from a pickup in Ashina Outskirts, but it's very missable, so keep that in mind. Other than that, it's just a Drunkard fight, nothing too special compared to all the other Drunkards we've put down on this journey.
