I've been using the one written by that one person from the Litch server, and 4 times now it's ended up so very not quite right.
First time, might have been my fault because a few times I didn't get the "feathers change" message and didn't correct it. Went from Chocobo Yellow to Marsh Green.
Second time, I was sure I got every single one to work. Went from Marsh Green to Royal Blue.
Third time, I was sure every single one of them worked. Went from Royal Blue to Grape Purple.
My goal is Void Blue.
Chart I can find indicates that it should be:
Doman Plum × 3
Valfruit × 2
O'Ghomoro Berries × 1
I won't be giving up if this don't work, but I really am getting upset.
