This test is best completed in a group of 4, but can be done solo using the Operator, the right warframe or with the help of Specters and/or Restores. In this room, there will be a glowing platform in the middle. Once a player steps on it lasers will activate centering on a single point. One player must stand in the middle of the lasers on the platform "enduring the hits" until the glass pillar on the side completely fills with water, causing the platform to fall away and teleport you to the reward room. The lasers on the side can be shot to reduce the incoming damage and make surviving the test easier. In addition, the area immediately around the platform has an invisible nullifier field, preventing the use of most buffs or abilities, but not all. The amount of time left is indicated by a column that fills up with water over time. Once the column is full after ~2 minutes, the test is complete.
- The middle laser can be blocked by shooting the lantern on the ceiling— it will collapse and block the laser.
- The two lasers on the first-floor sides can be blocked by standing near the rising block.
- The circle of lasers can be disabled temporarily by damaging their backs.
- The two lasers on the second-floor sides can be disabled temporarily by damaging the back of them.
This test rewards 
Endurance Drift.
Tips[]
- If you have completed The War Within, the entire test can be trivialized. While in your warframe, stand on the button and bullet jump straight upwards, and transfer to your Operator once you're clear of the nullifier field. You frame will then fall back down and you can walk off the platform while your invincible warframe stands on the button indefinitely. Ungeared operators can wait inside the broken glass water tube across from the one that fills as part of this trial and be safer from enemies.
- You can also use your Operator directly to press the button. Simply crouch into Void Mode and remain there, using Energy Restores to replenish your Void energy as needed (you only need about one Restore to regen full Void energy, and the laser damage is generally not strong enough to kill you in the time it takes to use one).
- Equipping your frame with a restorative Arcane such as
Arcane Barrier, 
Arcane Aegis, and/or 
Arcane Grace can trivialize this test as well, by regenerating your health or shields faster than the lasers can damage you. Hildryn, Inaros, Nidus, and other frames with high shield/health values are ideal. - Another method to clear the test while playing solo is to simply spam Team Health or Shield Restores to out-heal the lasers' DPS directly.
- A Sanguine Eximus Ancient Healer Specter from New Loka trivializes the amount of health restores needed.
- The test can be completed solo without expending restores by performing the following:
- A Trinity build with Vigor, Vitality, and Redirection to ensure maximum possible effective health. Add Streamline, Flow, and/or Fleeting Expertise to ensure that Blessing can be used at least 6 times consecutively. Install Rejuvenation to prolong the time spent in the circle before healing becomes necessary.
- Destroy the lantern to block the middle laser.
- Stand in the circle but ensure that the frame is slightly off center, which will cause some of the lasers to miss. Fire on the two upper wall lasers whenever they are active to further reduce damage taken.
- Whenever needed, Bullet Jump out of the circle to the walkway above and cast Blessing, then return to the circle. Note that the circle's nullifying effect will remove Blessing's damage reduction.
- A
- Although the circle will block MOST enemy fire should enemies decide to attack you, it will NOT block grenades.
- The test won't fail if Inaros gets in his sarcophagus, allowing other players to revive him and continue the test.
- You can also have a squad mate (if you are in a squad) bring a range Cataclysm Limbo which can disable both the circle lasers and the second-floor lasers in one cast of Cataclysm.
- Another excellent way to disable the circle lasers and the 2 lasers on the second floor is to use Banshee's Sound Quake with enough range, completely disabling all lasers in the area simultaneously. Repeat the ability if lasers become activated again.
- While you will not receive buffs and healing from allies while you are in the circle, you will still receive overshields from Trinity's Vampire Leech Augment, which will trivialize this test.
- Any Warframe with Adaptation equipped will take a very small amount of damage from the pure Impact lasers, trivializing the challenge.
