I am starting to collect some Pets and I was toying with one and ended up removing Trickster by accident from Legend Jester due to some lag I had. When I went to use an Amethyst to try and replace it, it appears you are unable to use.
Furthermore, you cannot use Dust to make any of them from the CODEX.
For as much trouble as they are to get, it sure seems like a real bottleneck for Pets.
Lastly, as you collect them, you will need to use another Character or eat up some valuable bank space to save them due to not being able to use the CODEX to remake them.
Any plans to change being able to make them from Dust out of the CODEX?
