Destiny 2 Curse of Osiris – A Deadly Trial Quest Guide

After completing The Gateway quest on Mercury, your journey in the Curse of Osiris DLC continues with A Deadly Trial. This is the second quest in the expansion, taking you to Earth’s European Dead Zone (EDZ), where you’ll work to revive Osiris’ Ghost, Sagira. This guide will walk you through the quest step by step, ensuring you complete it efficiently.

How to Start A Deadly Trial

To begin the quest, open your Director and travel to the EDZ. Use the Trostland Landing Zone for the quickest route to the quest marker. The quest flag, marked with Osiris’ symbol, is located nearby. Interact with it to start A Deadly Trial.

Step 1: Travel to Maevic Square

Your first objective is to reach the hidden Osiris temple in the EDZ.

1. From the landing zone, head down the main street, then move through the ruined buildings until you reach Maevic Square.
2. This area is occupied by Fallen enemies. Clear them out to progress.
3. Once the area is secure, hop onto a Heavy Pike (these are located nearby) to prepare for the upcoming battle.

Tip: The Heavy Pike is useful for dealing heavy damage quickly, so take advantage of it while you can!

Step 2: Destroy the Walker Blocking the Road

Moving forward, you’ll encounter a tunnel blocked by a Fallen Walker Tank. You’ll need to destroy it to continue.

• Use your Heavy Pike or a Power weapon to target the Walker’s legs.
• Once enough legs are damaged, the core will be exposed—shoot it for massive damage.
• Keep moving to avoid its cannon fire.

Once defeated, the tunnel entrance will open. Drive through it to reach the next area, Hangman’s Pass.

Step 3: Clear Out the Fallen at the Radio Tower

Your next big challenge awaits at the Radio Tower, where Osiris followers have set up a base. This Respawn Restricted Zone means you’ll restart the encounter if you die, so stay sharp.

• Take down waves of Fallen as they try to stop you.
• Watch out for tougher enemies like Captains and Servitors—they hit hard.
• Use cover wisely to avoid getting overwhelmed by gunfire.

Tip: Arc weapons shred Fallen shields, so equip one to make the fight easier.

Once you clear the area, head inside the hidden temple.

Step 4: Enter the Temple and Revive Sagira

To access the temple:

1. Climb halfway up the Radio Tower.
2. Look for a ledge on the backside of the tower and drop down.
3. This leads you into the hidden temple area.

Inside, you’ll find a console where you can insert Sagira. Doing so successfully fuses her with your Ghost, completing the mission.

After completing A Deadly Trial, you’ll automatically return to Mercury, where the next quest, Beyond Infinity, will become available. This will continue your journey into the Infinite Forest.

A Deadly Trial is a straightforward but action-packed mission, with intense Fallen battles and a strong emphasis on movement. Make sure to use your Heavy Pike, bring Arc weapons for shielded enemies, and take advantage of cover during difficult fights.
