The Temple of Death 'flag' on the map is just the area where the four sentinels where. There's another Death Temple? Why the hell would the game designers put a Death Temple flag on the map, then leave clues to check the Death Temple, and then have a completely other location be the actual Death Temple? I can't go anywhere else (including into the Temple) on the map because of the Death Knights. I can't sneak into the Temple because it's surrounded by enemies and if I start a fight with them a Death Knight always joins in and I can't run from a fight because of an ability I picked. So I'm stuck fighting and dying.

Well if I can't get the bones from the Temple fine, if I could just get the spell to make the ability to weaken Death Knights that would be great. I have the diary and I have the vial of blood. I just need to know where the spell is to mix with the blood.

Once I have that the Death Knights are manageable and I can move on with this map.
