Titania Thermal Sunder | Corrupted Mods Farm | Early Platinum Farm Solo Part 125:15

It's Nei here. Here I'm showcasing my thinking when running Orokin Vault.

The best way to find the Orokin Vault is to blitz clear all open doors till extract site. The faster you clear the better. Repeat it till you remember the doors position.

Orokin Eye:
Short range 150m; about 2 tile set coverage at most.
Distance to extract. Shorter is more effective.
Where to deploy?
Multiple big tile set/corridor in adjacent makes for wasted coverage.
Vault might be at spawn/extract or at an obscured location.
Won't know which room is cleared and whether a room is connected to another tile set.

My Conclusion: Fundamentals is always 1st. The Orokin Eye is an added ways to find it but not the main way. Either way, for me it works at most half the time as there's too much variables. Welcome to try as different people will have different results.

Remember these steps:
1. Mark. Mark the door you came from to establish your general direction and to prevent yourself from double clearing.
2. Capture. Capture the target immediately when you're in the same tileset/corridor.
3. Count. As some corridors have 3, 5, and 7 doors, you only need to remember the open ones that you haven't cleared yet. Clear the extract door last.
4. Blitz. Blitz clear the open doors one by one till you reach the extract site. If you find yourself in another corridor, repeat step 3 and 4.

In case you overlooked it, just extract as double clearing is not worth your time. Remember that sub 3 minute run is optimal. With enough run you'll subconsciously remember the tiles and the possibility of the vault location. For a chill run, just run public squad.
