Grab a dragon, fly directly down so u wont aggro the dragons, activate sprint (or w/e it was called), navigate into the hole from one of the diagonal cracks so u won't aggro here either, stay under the plates so u won't aggro though if u do it's most likely one of the 45(+)k hp dragons on which u just activate the DoT and 1 blast while your taking the mages out, when u move from one to another just stay low enough and when your on the last plate (highest) activate regen, don't mind the dragon(s) just shoot em mages down and when done, sprint fly back to temple, watch porno or just leech here and when ur char goes afk the mages have respawned and time to fly again.
Grinded 71-72 pretty painlessly so imo is useful
