after the To The Lair you can do 1 daily solo mission that starts with "Cracking the Crypts". There are 4 differnet one.
This Dungeon has a maximum duration of 3 days. This Daily quest may be randomly reissued after 18 hours while an old, empty instance of your Zone is still active. When entering this dungeon, if it is empty then leave the zone and use the Reset Button in the Dungeon Finder's Persistent Instances tab to reset the 'Ancestral Crypt of Vyl'Tayne' zone timer.
The dungeon is a Solo Instance zone therefore a mercenary can not be used nor can another player provide any assistance. If appropriate carry healing potions, remedies, etc.
At this point, a message flashes on the screen: Lady Z'Tozia says, "I shall rend thee!" and this spawns Lady Z'Tozia ( -207, 0, -24 ) Copy/waypoint -206.86, 0.07, -24.06 in the entrance room of the crypt.
Kill Lady Z'Tozia.
Now that all the crypt guardians have been cleared the quest updates.
Quest updates to read "- I need to collect a jaw bone" This will be a fedid corpse (skeleton) ( -184, 0, 4 ) Copy/waypoint -183.54, 0.07, 4.20 on the ground surrounded by "glow particles", and can be interacted with. Select this item and "Remove the Jawbone!".
A second item from a canopic jar ( -167, 8, -11 ) Copy/waypoint -166.80, 8.47, -11.37 is requested , with the same behaviour. This is upstairs with "gooey bits" in it.
Collect the second item, and the quest updates, and you receive a reward of a "Crone-Speak key."
Right click this key in your inventory, speak the listed words and it creates the sub-quest A Chrone-Speak Key which immediately completes and rewards "A Translated Key" of a particular type (an Emerald, Ruby or Sapphire).
The journal step now reads "Time to loot this crypt!".
An ornate chest spawns at a random location within the zone (no glowing particles) e.g. ( -175, 0, -17 ) Copy/waypoint -174.93, 0.07, -16.67.
Click the chest and Loot it!. using the An Ancestral (key type) Key with the text: "Open the ancestral (key type) chest."
Accept this quest and receive a "Vetrovian Crypt Spoils" reward when this sub-quest automatically completes on opening the chest.
Return to Sister Ghoulinda in her lair in the Mahngavi Wastes to complete this quest and receive the rewards listed below.
You may do another Cracking The Crypts quest once every 18 hours.
