What is Diablo Immortal 3rd Rune
After completing the 9 Lamp Puzzle for the first rune and battling it out for the second you make your way towards the third Rune, to finally be completing the “Lost Rune” quest and collect the third Rune.
Key Takeaways
- The Diablo Immortal features three factions: Shadow, Immortals, and Adventurer, and players must slay demons and solve missions to progress.
- The “Lost Rune” quest requires players to solve the Mirror Puzzle to obtain the third Rune.
- The Mirror Puzzle can be found in the mirror world during the quest.
- Players must rearrange the six mirrors to deflect the beam of light onto the Third Rune.
- Mirrors can only move in two directions and arrows help determine their placement.
- The second mirror on the left is pulled to the left in the second image, the second mirror to the left is pulled down in the third image, and the third mirror to the right is pushed down twice in the fourth image.
- The beam finally deflects off the remaining four mirrors, forming a pattern and reaching the Third and final Rune.
However, the Mirror Puzzle blocks you from obtaining it. Lucky for you we have set up a guide to overcome that obstacle.
The Mirror Puzzle is found in the mirror world during the “Lost Rune” quest. You will have to form a pattern by shifting the mirrors to deflect the beam of light onto the Third Rune. It may sound tricky which is why I have set up a guide that will show you exactly how it’s done. I have also attached images to better understand the Guide.
How To Complete Diablo Immortal Mirror Puzzle
When you enter through the gate you will see 6 Mirrors with 2 of them Deflecting the beam. You will have to rearrange the mirrors in a way that the Beam hits the Third Rune. Below we will show you exactly how it’s done.
The mirror can only move in two directions. With the help of arrows, we can determine where they must be placed. In the second image, the left-most mirror is pulled to the left allowing it to be used to deflect the beam.
In the Third image, the Second mirror to the left is pulled (Down) in the direction the arrow was pointing. Thus forming the Pattern above.
In the Fourth Image, the third mirror to the right is pushed down twice (Double Arrows) to allow the beam to hit the mirror in the centre.

Finally, the Beam has deflected off the remaining four mirrors, forming a pattern as shown above and reaching the Third and final Rune.
We hope this guide was helpful for you and helped in solving the Mirror Puzzle. I would also like to thank Kibbles for the images provided. If you have any more queries regarding Diablo Immortal you can head over to our Guide section where you will find the answers.
