Chaos Rosalia location and Yatta Cavallo transformation guide
The short answer: use a side door near the top of Astral Stair
Item | Details |
|---|---|
Relic | Chaos Rosalia |
Stage | Astral Stair |
Location | Northeast of the starting point, at the end of the highest side room |
Unlock | Yatta Cavallo's level-80 transformation |
Reaching the upper end of Astral Stair is not enough. Enter a side door in the wall near the highest section, then continue to the end of the room.
How to get Chaos Rosalia
- Enter Astral Stair.
- Travel upward to the highest section of the vertical corridor.
- Use a side door in the left or right wall instead of an end door that loops between the top and bottom.
- Continue through the room and collect Chaos Rosalia at the far end.
- Check the collection or the Add: Chaos Rosalia achievement.
What changes after collection
After collecting Chaos Rosalia, use Yatta Cavallo and reach level 80. Yatta Cavallo transforms and the main weapon changes into Yatta Daikarin. Collecting the relic does not trigger an immediate transformation by itself.
If you cannot find or use it
Problem | Check |
|---|---|
A door sends you to the bottom | You used an end-loop door; enter a wall-side door instead |
Nothing is visible at the top | Continue into the northeastern side room |
Level 80 does not trigger the transformation | Confirm that Chaos Rosalia was collected before using Yatta Cavallo |
