0. Make sure to keep a safe backup before you perform any edits.
1. Make sure you already defeated the champion on your B2W2 save, and have access to Black City/White Forest.
If you didn't, go ahead and defeat the champion
2. Download the Generation 5 tool.
3. Load up your save in the BW Tool, open the 3DS Link (Dream Radar) tab.
8. You've received Therian Landorus
9. Once received, fly to Black City/White Forest, and make your way to the Abundant Shrine.
You will need Surf and Waterfall to get there, and bring the Therian Landorus. The NPC should be there.
(if you're already in the Abundant Shrine, you need to exit and re-enter to reload the area for the NPC to load)
10. Talk to the NPC, receive the Reveal Glass
The Reveal Glass received works!
