Item description:

Load up the save and beat Oni and then you will face Tsukumo after him. both shouldn't take more than 2 minutes as my character is maxed out. also you can get 10 fallen shadows with this save. i think i have couple left. only these 2 then platinum.

WARNING: make sure not to get this before the awaken trophies or final boss. you need at least 3-4 days time gap between this and final boss trophy to make it look legit. the post game dungeon is actually longer than the game itself. crazy, but it is. awaken trophies MUST be unlocked before it considering how long sanctum of rebirth is.
