Den of Behemoths in Bloodstained: Ritual of the Night is an oversized area you’ll only reach on the path to the game’s true ending. It’s not physically connected to the rest of the game’s world, so you’ll have to create a portal to get there.
Den of Behemoths connects to Garden of Silence and Glacial Tomb.
Below, we’ve included a complete map of Den of Behemoths with a few notes about the area.

Once you defeat Zangetsu in Oriental Sorcery Lab and receive his Zangetsuto, you can head to Hall of Termination to continue toward the game’s true ending. Halfway through your fight with Gebel, attack the moon instead. This will break Gremory’s hold on Gebel. Gremory, as the moon, will then flee to the Garden of Silence. Head there, and attack the moon again to create a portal to Den of Behemoths.
Much like Texas, everything is bigger in Den of Behemoths. The environment and the enemies are all oversized — and the enemies’ stats are proportionately higher, too. There’s not much to do here. You’re just trying to survive your way through it to reach Glacial Tomb.
