Objectives
Search the Funerary Urns for the bones of Lady Dunhyld As soon as you click the first Urn, Skeletons start spawning at every corner of the tomb, their spawning rate increasing with every other Urn you touch. Lord Dunhyld (unique Wraith) will also be summoned with each opened Urn, but on the first and second Urn, bringing him below 25% Life will despawn him until you open the next Urn. After all three Urns are opened, the number of Skeletons summoned becomes finite (but reasonably overwhelming), Lord Dunhyld becomes permanently summoned and killable. To end the event, you need to kill the Wraith and touch the sarcophagus once.
 * Activate all three Funerary Urns located nearby (highlighted on the map)
 * Defeat Lord Dunhyld
 * Place Lady Dunhyld's bones into the Dunhylds' sarcophagus

Originally, killing Lord Dunhyld was not required (a Champion pack of Skeletons would spawn at the sarcophagus instead). If he was still alive (well... not destroyed) when you finished the event, he would simply despawn, giving no credit and no loot.
