Effect: Headshots only.
On Round 60 or above, go into Tyr's Head and get five headshots in a row. If done correctly, you'll hear Mister Peeks laugh and the relic trial portal will be available in the Dry Dock, near the Flammenfalle trap. The relic trial is: Activate and survive all holdout locations.
There are six total lockdowns you'll need to activate by interacting with Mister Peeks, who can be found via the purple light in the sky.
