Starting area
The Spire, in the Underpass
Recommended
Activate the nearby fast-travel door before you climb.
Traversal
Guides describe the climb with different names, such as Shift or Gravity Shift. The production relation data does not confirm a hard traversal gate here, so it is not shown as required.
Traversal used hereWechsel
Quick answer
Reach The Spire in the Underpass, climb it and enter the Astral Plane. Follow the route to the central locked door, then find all three Astral Keys and return. The opened route leads to The Physicist. Beat the Resonant and choose between Spike and Astral Rebuke.

What changed?
The Resonant is defeated and its reward choice is resolved. This page does not invent world-state changes; anything that is not read from production stays out.
What next?
Continue your current story. If the next objective is unclear, let the tool pick up from your state.
What should I do next?Choose your ability
Beat The Physicist and pick one combat ability. This page does not pick a winner.
Not sure which one fits your build? Compare them first.
Compare Spike vs Astral RebukeRewards
The main reward is a combat ability choice. Numeric rewards and artifacts are database fields, so this page does not hardcode them.
Artifact
Data gated
Other rewards
Read from production when available
Untapped is a state, not a second artifact. The canonical artifact identity stays pending until the relation is closed.
Stuck on The Underpass Resonant?
What's happening?
Why can't I continue?None of these? Open the Quest Troubleshooter
It is usually one of these: a missing prerequisite, a wrong tracked quest, a traversal requirement, an interaction requirement, a missing key, or a known issue. Check which one applies before calling it a bug.
The quest isn't in my log
Check that you have reached the Underpass and that the right quest is tracked, then approach and inspect The Spire.
I can't climb The Spire
Check which side you approached from and whether you have the traversal progression the route expects before assuming a bug.
I reached the Astral Plane but the door is locked
This is expected. The locked door is the main obstacle of this quest. Find the Astral Keys.
I'm missing one Astral Key
Open the Astral Key tracker and check which route you have not marked. Use the Which Key Am I Missing? helper.
I have all keys but can't progress
Check the key state, the door interaction, any remaining branch and your active objective before concluding the quest is broken.
I reached the boss but can't beat it
Open the full boss guide for attacks, phases and counters. This page only owns reaching the fight.
Known issue
Only problems listed in the updates registry are labelled as known issues.
