Note that if a player has a low combat level, they will likely receive damage from the surrounding monsters while searching the crates for the key. The key is first used in the Waterfall Quest. The key is needed to unlock the door where the gnome named Golrie is hiding from Hobgoblins that have invaded the dungeon. Once the door is unlocked, Golrie will give the player Glarial's pebble, which is required to enter Glarial's Tomb near Baxtorian Falls. Players can repeat this after the quest to re-obtain Glarial's pebble. It is recommended to keep this the pebble in the bank, or instead Glarial's amulet once received, in order to avoid the need to speak to Golrie again at a later date, since the amulet is required to enter the Waterfall Dungeon.
