Walkthrough
Level 1: Speak to Olaf Olafson in Olafstead to make your party taken to Raven's Point. Once inside, head north, as indicated by the quest marker on your map. Just before reaching your destination, you will approach some doors, which will open for you. In this room there are 4-5 pop up groups of two Destroyers per group. They are fairly easy to kill. Once you kill these groups your Quest Log will update. Talk to the Shrine of the Raven Spirit to obtain the skill Raven Blessing. Head south back out of the room, and follow the groups of Destroyers, killing them as you go.

The best approach is to take out the Destroyer Tremors first. Try to spread your party if encountering any Destroyer of Hordes, as they use Barrage, typically backed up by a Destroyer of Hope using Order of Pain. An interrupt Ranger or Mesmer to counter the Tremor's elemental damage is also useful.

Level 2: Once you reach Level 2 of the dungeon, talk to Olaf if you want the Raven Blessing skills again. Possibly a bug, but there is no quest marker on this level, and on level 3. This level comprises of mainly Scourge Vaettir, Shadow Vaettir, and Mist Vaettir. Kill the Scourge Vaettir first, as they use Scourge Healing which makes life hard for your monks. Head in a north-west direction to reach the portal to Level 3 of the dungeon - not very far.

Level 3: At the beginning of Level 3, it will appear you can go left or right (right is the shorter route) facing two Destroyers either way you go. However when you aggro one group, some more will pop up, and the other side aggro's as well - which can take even the most prepared players by surprise. Be ready, again attacking the Tremors first, followed by the Destroyer of Hordes barragers. Head in a due south direction. You will quickly reach a resurrection shrine, past which you can see an Asura Gate blocked by some more Destroyers. Beware of additional Destroyers pop ups in this area. Attack the Destroyers first, and don't try and run to attack the Asura Gate yet.

After killing all of the Destroyers, attack and destroy the Asura Gate. A cutscene will take place between Olaf and Ogden. After that, you are returned to Olafstead.
