Brilliant Dumbledore...

Alrighty, I've double checked. If you're stuck, Tonic for Trace Detection works to draw Brilliant Foundables. (Dark Detectors apparently *don't* for this event.) TFTD spawn appear (roughly) every three minutes, and only for you, but they last fifteen minutes, so you only need to check the game now and again.

Anywhoodles, there's still some hope if you need Albus.
