Existential Crisis

November 16 update: The Existential Crisis achievement now functions as described.

This makes the achievement much more easier, as you just pick up the orbs that you spawned.

In case you want to track the achievement and see who fails it, you can use the Instance Achievement Tracker Addon.

This is only able to be done without pets or anything that has a health pool, this is still an issue after patch 8.1 has been released. Wiped for 1.5 hours with pets out, after not having them we completed first attempt.

This was stated prior by:

Doing this achievement tonight after the hotfix we found out pets hit by Obliteration Blast \ Imminent Ruin spawn orbs and getting that orb WILL fail the achievement, make sure you have NO PETS at all (even things like Vanquished Tendril of G'huun or mistweaver statue ect).

We spent an hour on this before seeing your post. Got it first attempt without pets. THANK YOU!

Hard to definitively say because nobody could tell what exactly was failing my group to start, but the number of unexplained failures went down significantly after removing pets from the raid, and we got it within four or five pulls.

This achievement has been fixed and works as intended, you can only collect your own orbs.
