Quest: A Deeper Secret
Location Map:
HERE
So off you go down the steps into the Ogre part of the tomb (you can use the location map to find all 3 places the names spawn). You will notice on the map that the bottom half of the tomb is made up of a big hallway that goes around in a square shape. There are 3 specific rooms that are located off of this hallway that will have the names spawn in it. Each name will have a place holder attached to it, so be warned that you may need to kill its place holder in order to get the named to spawn.
NOTE: Mostly all the ogres do not see through invis. There are exceptions to this rule, for example, the Mystics do see through invis, so watch out!

If you take the hallway clockwise then the first room with a named in it you will run into would be Graok's. Graok FaceSmasher will be located in a smallish room with 2 levels (The letter I on the
Location Map). He will be standing in the back of the room at the top level, on the right hand side. He will be a level 37 4dot mob, and won't be anymore of a challenge than the rest of the ogres.

The next one you will come up to will be Gorlash Toxil's room. Gorlash Toxil will be located at the very back of the room and you will notice if he is up right away. He will be the biggest and meanest looking ogre and have a name that is all in capital letters (plat coins!). If he is not up, you will have to kill the mobs in the back there and hope he appears during the next respawn. Gorlash Toxil will be a level 37 5dot mob and with a good group of friends should be a nice take down. Loot him up (he should have some nice tank or caster loot) and make your way to the last room.

This last room should have Gorrar Kingslayer located inside of it. The room itself should look very similar to the room that you found Gorlash Toxil in, and Gorrar Kingslayer will spawn in the back of the room (also similar to Gorlash). He will be another 37 4dot mob and should act very similar to Graok as far as difficulty level (and their ugly looks!). After you take him down your quest should be complete! Make your way back to Dakren Flamehammer for the turn in, and his trust.
