The encounter began as another tank-and-spank
"as any other" instead of "as another"
while green cause proximity damage
inches from the lip of temple's edge
"inches form the lip of the temple's edge"
The fight operated much like Algalon's Big Bang, of Ulduar fame
Mentally I don't pause here as Algalon's Big Bang is of Ulduar's fame so that's one idea. Since you follow this bit with an ellipses I would just remove the comma.
This was Ultraxion test:
"This was the Ultraxion" or maybe "This was Ultraxion's"
I thought back to DoD initial steps
