Pixelmon Mod

I noticed in the patch notes that it was added along with other pokeball types from Legends, however I was unable to locate a recipe for them in the wiki nor any mention of them in the lids section.

Afaik the only way to obtain it (aside from commands or creative) is to have a Master Ball break when thrown outside battle. It was mainly added for that purpose, to be in line with all other Balls for that mechanic.
