Ground astral rune

Ground astral rune is a quest item used in the Dream Mentor quest. It is created by using an astral rune on an anvil and subsequently using the resulting astral rune shards in a pestle and mortar.

Ground astral rune is ingredient in the shared dream potion needed in the quest.

It has no other use thereafter, however.

Trivia

 * Ground astral rune is one of the two magic-imbued runes that can only be ground by pestle and mortar, aside from mud rune.
