How to Get the Rune & Key in Armless Detective Roblox Halloween Spotlight Guide

How to Get the Rune Badge

To start the Rune quest, head into Armless Detective and queue up the Curse Cathedral case. The main goal here is to complete the investigation once, which includes solving puzzles and collecting three pieces of evidence.

Step 1: Start the Investigation

Once you’re inside the Cathedral area, pull out your magnet gadget to begin solving the magnetic ball puzzle. Move the ball along the yellow and blue paths carefully — avoid lifting it when it’s stuck, as it can glitch. Once that’s complete, start exploring for evidence.

Step 2: Collect Three Evidence

You’ll need to identify three clues to solve the case. These vary per player, but here’s an example setup:

1. Aggressive Ghost (Vengeful Spirits) – Use your UV light to locate a ghost. If it attacks you, it counts as valid evidence.
2. Grave Robbery – Pick up the shed key, open the nearby shed, and use the shovel to dig graves. If you find an empty grave, that confirms the grave robbery clue.
3. Hidden Evidence – Use your gadgets (like magnets or UV) to search bushes or walls for extra hidden clues.

Step 3: Complete the Mirror Puzzle

Head to the mirror room and rotate the mirrors to direct light to the gem at the end. Use your magnifying glass to activate it — if it glows correctly, it’s complete.

Step 4: Identify the Suspect

Once you’ve gathered your three pieces of evidence, open your journal, combine them, and identify the suspect. It’s random for each player, but once you select correctly and submit, you’ll complete the case and unlock the Rune Badge.

How to Get the Key Badge

After earning the Rune Badge, you can now go for the Key Badge. This is an extended version of the same Curse Cathedral quest but with an extra objective involving a statue activation and a Halloween mini-game.

Step 1: Replay the Cathedral Solo

Queue up the Curse Cathedral mission again, but this time solo. During your investigation, you’ll find a new statue area with a small button. Use your magnet gadget to activate it — this triggers the next part of the quest.

Step 2: Complete the Investigation

Finish gathering evidence and identify the suspect again, just like before. Once the crime is solved, the statue event will activate a new sequence.

Step 3: Trick-or-Treat Mini-Game

After solving the case, you’ll be transported into a skateboard mini-game. You’ll need to press keys quickly as prompts appear and reach the end without falling through holes. Don’t worry if you fall — there are checkpoints to help you progress.

Stay alert for obstacles and move quickly to escape the collapsing map. Once you reach the end of this chase sequence, you’ll unlock the Key Badge and complete the event.

The Armless Detective Halloween Spotlight event mixes puzzle-solving with a spooky twist, rewarding players who explore carefully and think fast. Both the Rune and Key badges are fun to unlock and come with a satisfying bit of challenge. So grab your tools, enter the Curse Cathedral, and uncover the mystery before the ghosts catch you — the Rune and Key await those sharp enough to solve the case.
