According to a rarity convention established in 24w33a, items must inherit the highest rarity of all its crafting ingredients.
From the 24w33a changelog:
Any item or block which can be crafted must inherit the highest rarity of its crafting ingredients.
β¦any crafted item which has only Common crafting ingredients must also be Common
However, the Dried Ghast has a rarity of uncommon while both of its crafting ingredients, the Ghast Tear and the Bone Block, have a rarity of common, breaking this convention.
Steps to Reproduce:
Get a crafting table and the crafting ingredients
Place down the crafting table and open the UI
Insert the crafting ingredients into the recipe
Observe the ingredients and output
β Observed: Dried Ghast has uncommon rarity while its crafting ingredients have common rarity
β Expected: Dried Ghast would inherit the common rarity from its crafting ingredients
I think that it would be better if the Ghast Tear was uncommon.
