Grade 4 Skybuilders' Umbral Flarerock

Purchase: No

Sells: 7 Gil (NQ) [Market Prohibited]

Each chunk of flarerock is capable of releasing enormous amounts of fire-aspected aether. Unfortunately, for that to occur, it must first be warmed for three days under a medium-sized duck, which limits its usefulness somewhat.
Can only be gathered during an umbral flare.
Used in expert crafting recipes.
