Glarial's Tomb is a dungeon inhabited by 3 level 61 moss giants located underneath the tombstone south east of the Baxtorian Falls. To enter, the player needs to use Glarial's pebble, which is obtained during Waterfall Quest, on Glarial's tombstone.
Players cannot bring any of the following with them when they enter the tomb:
In addition to that, players cannot bring Summoning familiars and cannot use Prayer.
If a player has any of the above items and tries to use Glarial's Pebble, it will say "It fits perfectly, but nothing happens."
Glarial's tomb is also involved with the Roving Elves quest. The player has to kill a moss giant completely unarmed and unarmoured (food and potions are allowed) to obtain a Consecration seed.
The Tomb has a roaming Mysterious ghost outside of it named Valdez, who can only be seen when wearing the Ring of visibility. This ghost starts the Ghostly robes miniquest.
