- Available for purchase for 8,000 souls at the Giant Blacksmith.
- All Crystal Lizards are guaranteed to drop two twinkling titanite each.
- Common drop from Giant Clams.
- Common drop from Guardians.(AotA)
- Found in a chest in the first half of Anor Londo.
- Up to four can be obtained by trading the different Moss Clumps with Snuggly the Crow.
- Giant Clams in the Crystal Cave: After the boss is defeated, a bonfire is unlocked just next to a large group of Giant Clams which drop Twinkling Titanite quite commonly (be careful not to be overwhelmed by them; Ring of Fog or Hidden Body are helpful).
- Guardians in the Royal Wood: Also rather easy to farm but they are located further apart than Giant Clams over a larger area and are arguably more dangerous in combat. Presence of other enemies, longer distance from the bonfire and worse visibility in the area make farming in general slower, but there's less possibility of being overwhelmed by multiple enemies.
