Requires OptiFine!
This resource pack for Hypixel Skyblock makes it easier to tell which rarity a Scatha pet item has:
Note: I unfortunately cannot change this for the GUI slots only, so it also overrides the model/texture when held in the hand - luckily, due to how OptiFine CIT works on skulls, it doesn't override it when worn on the head, so the actual pet is unchanged!
Why?
Because I already made the Scatha rarity textures before to use as Discord emojis and someone suggested to make a pack out of them.
Why not for all pets?
Because that would require setting it up for every single pet's available rarities individually along with making the textures, which I can't be bothered to do. (Scappas = best pet anyway <3)
