In the Fortress Indomita, there are several items and activities to track down for 100% completion:
- Collectibles: 5 total
Fortress Indomita Collectibles
Vault Symbols
Vault Symbol #1

To reach this vault symbol, you’ll need to pull down a grate using your grapple to reach a vent with a hidden room.

This will be during the “Kill Idolator Sol” objective of the Rush the Gate main quest.

Vault Symbol #2

This vault symbol can be found on a high ledge in the room just before the vending machines. To reach it, we jumped onto the railing and then double-jumped to the ledge.

ECHO Logs
Sticks and Stones

After collecting the first vault symbol above, turn around and exit through the opening. Head to the other side of the platform to find a grapple point on a high ledge.

From there, you’ll be able to reach the ECHO Log.

A Timekeeper’s Life for Me

After taking the circular elevator up, you’ll find this ECHO Log on the ground next to the Active Checkpoint.

Fear and Self-Loathing

This ECHO Log can be found on the west side of the room just before the vending machines.
