Twilight Gems: Assassins(10%) Twilight Stones: Dancers(10%)
Traverse Town is in KH1 but not in KH2. Whereas, Twilight Town is in KH2, not KH1.
This depends on whether you have KH or KH2. If you have KH2, you must get all the crystals, an Orachilum, and all 13 Orachilum+, and the Ultima Recipie. Then go to a Moogle and Synthisize. In KH1, you need 5 lucid Gems, 5 Thunder Gems, 5 Power Gems, 3 Mystery Goo and 3 Gale.
Twilight Gem: Assassin(Twilight Town, The World That Never Was)
I normally go to the world that never was, just after where you beat Xigbar. You can also go to the tower in Twilight town.
Have you tried near the end of the game to go into Twilight Town's Old Mansion and fighting nobodies there? You get a lot of Twilight stuff there. If not, try another place with Nobodies.
