Wait nightmare cookies and nightmare mystcase are undead to heal bomb them...? I will have to take a look at that.
I looked at verits and mummy in nightmare. However they are relatively far away so I can't healer spam for SP, making orc zombies faster by sheer speed of the run instead of sitting for now. Yes it's 8% per verit but it costs more than all of my SP to kill one, making it way too slow for now....
The 250k exp from finishing the daily is a good goal to time it for the dreaded j49 though.
