All Oboro Relics
There are five Oboro Relics to be found in this stage. Here’s where to get them:
Oboro Relic #1


From the start of the stage, keep running right till you enter a bunker that triggers a gauntlet. Defeat all the enemies to spawn a chest. This chest gives you the first Oboro Relic.
Oboro Relic #2


From the Bunker Shrine, continue moving forward. When you reach the third bunker, just past the two grapple points over the ramp, break through the Yokai Floor to trigger another gauntlet.

Defeat the enemies here to spawn the chest containing an Oboro Relic.
Oboro Relic #3


In the Secret Bunker area, head left and complete a long obstacle segment to reach the opposite side of the locked gate near the shrine.


Activate the switch, then head right to find a chest up ahead containing the Oboro Relic.
Oboro Relic #4


From the Throne Room Shrine, drop down and head left to find a passage beneath the climbable wall. Roll under to reach a room with falling pillars.

Use them to cross to the far end of the room, where you’ll find a chest on a platform containing the Oboro Relic.
Oboro Relic #5

From the Throne Room Shrine, head right and break through the Yokai Floor barriers to reach a room filled with acid.

Jump across the disappearing platforms on the left to reach a ledge with a chest. This chest contains the final Oboro Relic for the zone.
All Secret Chests
There are two Secret Chests that you can find in this stage.
Secret Chest #1

After riding down the three ziplines in the Siege Tower area, continue moving forward until you reach the grappling section. As you grapple across, look for a climbable wall above you.

Climb up to the platform and head inside to find the first Secret Chest. This chest rewards you with a Max Kunai Boost upgrade.
Secret Chest #2


From the Throne Room Shrine, head left across the climbable surfaces. On the far-left side, you’ll spot a climbable wall leading down. Follow this path and drop down to the lower section.


Head through the door on the right. This leads to a long parkour segment, at the end of which you’ll find the second Secret Chest. It contains a Lab Key.
All Elite Squads
There are three Elite Squads in The Assault Stage. Clearing them all gives you a Ninpo Cell Boost.
Elite Squad #1

From the starting point of the zone, continue heading right. The first Elite Squad symbol is right along the main path, so you can’t miss it.
Elite Squad #2

In the Secret Bunker area, head past the Oboro Relic chest to the left to find the second Elite Squad encounter symbol.
Elite Squad #3

From the Throne Room Shrine, head left until you reach the outside walls of the castle. Instead of climbing up, drop down to a lower platform and go through the door on the left.

This hidden area contains the final Elite Squad encounter for the zone.
