CommanderD posted some updated Krystal mod spritesheet tutorial images for his Cladun mod, which works with both Cladun Returns: This is Sengoku! and in Cladun X2 (both available on Steam).

CommanderD says that creating this spritesheet in-game should be straightforward, but will require a bit of copy-pasting. If you want to see the mod in action, and how to create the Staff weapon, check out the original post about it.
