Glarials pebble is an item received from Golrie during the Tree Gnome Village Quest. This pebble is used during the Waterfall Quest to enter Glarial's Tomb, which holds Glarial's Amulet. No combat equipment of any kind is allowed within the Tomb. If a player loses this item, they can return to the Gnome Village Dungeon and talk to Golrie to get another.
