Are you ready to put your stealth to the test?
At times, this cache will be nearly impossible to nab without being noticed. So, this test is NOT for the faint of heart. You will need to bring your "A" game.
If you think you have what it takes to pass the test, then go and get it.
How do you pass the test? It's simple. Just don't let the cache get muggled. If the next person after you is able to find it,, then you passed the test. This is proof that you were super sneaky, and you were able to find, sign, and return the cache to its designated hiding place without arousing the suspicions of any nearby muggles. Kudos to you!
REMEMBER, there is absolutely no shame whatsoever in coming back at a quieter time. But there IS shame in failing the test.
Good luck.
