You previously went through the trouble of obtaining shards needed for the Willbreaker and the time has come to forge the sword.
The next task is to make your way to The Founts and use the forge to remake the Willbreaker in hopes of being able to use it to reach Eris Morn.
As this is Eris Morn’s time of need, you won’t be going alone because Drifter will be there to back you up along the way.
How To Get Renascence Mission?
Upon reaching Quest Step 6 in Act II: Rites of the Deep quest, you will be able to start the Renascence Mission.
Attempting to start the mission will bring you to the Writ: Path of Ambition activity and you may need to select the mission itself from here.
Renascence Mission Walkthrough
At the beginning of the mission, you will spawn in The Mausoleum, where Drifter will be waiting for you after he recently reached out to join you.
Approach Drifter and once he is done speaking to you, he will head off and you may continue with the mission by making your way to The Founts.
Continue following the waypoint as this will lead you to The Founts and once you arrive, you will need to start forging the Willbreaker.
Once you reach The Founts, you will need to approach the Forge and interact with it to place the Shards inside of it.
After the Shards have been placed, Taken enemies will appear and you will need to defeat them to feed the Forge. (Do this until you reach 100% progress)
Crystals will appear nearby once the Forge is ready and you will need to destroy them to create a safe zone that will protect you later.
Once the safe zone has been created (there will be a barrier), move close to the Orb on top of the forge and wait for it to charge up. (This begins its detonation)
After charging up the Orb, quickly head to the safe zone that you created by destroying the Crystals and wait for the Orb to explode.
You will need to repeat the process of feeding the Forge, destroying the Crystals, and detonating the Orb 2 more times before you can proceed.
The Willbreaker will be completed after the third Orb detonation, and you will now be able to pick up the Sword and will need to test it out on your enemies.
Taken combatants will appear, and you will need to defeat them to demonstrate Sword Logic until 100% progress is reached.
After defeating the enemies in the area, continue by making your way to the Hall of Souls to make your way to the rift that leads to Eris Morn.
While Drifter makes a poor attempt to inspire you with his stuttering speech, make your way to the waypoint in the Hall of Souls.
Interact with the Sword and begin attacking the enemies in the area until all of them are defeated, which will remove a barrier blocking you from the rift.
You will need to attack the rift to open an incision between worlds and afterward, entering the rift will complete the mission and you will arrive at Eris Morn’s Throneworld.
Renascence Mission Rewards
Completing the Renascence Mission will reward you with loot just like the other activities would and at this point, everything was too fast to see what was obtained.
After this mission has been completed, you will now have access to the Noiseless Chantry, which is a part of Eris’s Flat (Eris Morn’s Apartment) that can be accessed through a rift.
The rift will now be present in Eris Morn’s Apartment, allowing you to travel to the Noiseless Chantry and back whenever you please.
Summary
All your efforts have been put to good use and with the help of Eris from beyond, you were able to forge the Willbreaker and cut through the material plane.
The incision you created allowed you to find Eris Morn in her Throneworld and now a connection has been made, and she is now alive and well.
However, there is more to be done as the issue on Dreadnaught persists and more challenges await as the Echo of Navigation still challenges you.
