Tips

• Try to destroy time crystals by reducing their health enough for EviscerateEviscerate (Special)Target the nearest enemy, attacking them for 110% damage repeatedly. You cannot be hit for the duration.
  Survivor: Mercenary or Blinding AssaultBlinding Assault (Utility)Stunning. Dash forward, dealing 300% damage. If you hit an enemy, you can dash again, up to 3 total.
  Survivor: Mercenary to destroy them, so that no damage is incurred from the resulting explosion.
• Drones and turrets can serve as distractions for enemies, allowing one to use Blinding Assault or Eviscerate to either finish off or soften enemies without risking being hit.
• All interactables spawn in the exact same location when restarting the Trial, making it useful for finding drones and turrets to help distract and kill enemies.
• Items in chests are static in the trial, meaning the spawned item from a certain chest or Lunar Pod will never change when retrying a trial. This is useful for finding items that increase the player's damage ( Lens-Maker's GlassesLens-Maker's Glasses

• Shaped Glass does not invalidate the challenge as it is not technically falling below 100% health. Rather, the 100% health value is reduced. The double damage can prove extremely useful; taking any damage fails the challenge anyway, so there are no downsides to doing this other than the lunar coin cost per attempt.
• Runs will have random artifacts active for the generated seed. Artifact of Command and/or Artifact of Glass are recommended for doing Ethereal due to controlled selection of items and the 500% damage increase, respectively.

• In Prismatic Trials, going through Bulwark's Ambry's portal causes the trial to end, granting the player victory and the achievement. If Sky Meadow is the first or second stage in trial, this is an easy way to skip a stage.
