¶ Coal Petal
The Coal Petal serves only as a crafting material for certain Holoitems and has no other practical use. Despite the Coal Petal having an enchantment glint applied to it, it does not contain any actual enchantments.
¶ Crafting
The Coal Petal does not belong to any specific Hololive member's collection and does not have a prerequisite to unlock it's crafting recipe because of it. It is however used in the Gnaw belonging to Haachama's collection.
To get a Coal Petal, a coal ore block must be smelted in a furnace or a blast furnace.
