Overview
The start of this mission is easy as long as you carefully pull: Mhenlo's auto-attacks help a bunch and the two healers can't really die here.
There are two possible Warden bosses: Ranger and Mesmer. Ranger is a lot easier as he can be trivially LOS blocked.
His group can contain warriors and/or rangers: warriors will make pulling a lot harder.
Once the central room is cleared, be careful not to skip through the cinematic too quickly or Danika might run into all of the statues to get the urn.
At this point Mhenlo is gone, and you have to be more careful. Every once in a while you are rupted (not knocked down!).
As long as you carry the urn, Danika will follow. If you drop it she will stay in place, though she still walks over to heal you.
You can stand in a collapse zone to quickly level the urn and drop it to prevent a lot of damage.
Stone Guardians can all be pulled one by one, and are weak to cold damage.
You can take three paths: left, center, or right. Right is probably the hardest one as it has lots of healers.
Middle is tricky, with more wardens with varying compositions.
Left has warriors, melee necros, and an Elementalist boss that you can kill at longbow range. All have Oni's (so walk carefully).
At the end, make sure to kill the boss last, as as soon as he is dead Danika will rush towards the end.
