LOCATION: Dropped by a few mice in the Forbidden Grove. Gargoyle, Gate Guardian, Golems, Scavenger and Sorcerer Mice. Sorcerer mice at the Acolyte Realms may also drop these.
DESCRIPTION : These magical stones originate from another plane of existence. Little is known about who or what may have brought them into this world.
You'd need to collect 60 Runes for the Ice Maiden Trap. I'd recommend using the Runic Potions instead, when getting Runic Cheese
