My build is:
shadow form
Deadly paradox
Sliver armor
shock
aftershock
recall
dark prison
deaths charge
I kill the monolites at the second shrine. I also have requim for brain and pick up/drop the ancient tome to spawm some more margonites to have 25 kills. Then I flag heroes somewhere near temple(not so near just as far as recall would maintain) And I use recall on a rondom hench. Then I go and target the first shrine. Deadly paradox>shadow form>use the first shirne at right side>shoadow step to a boss(kill the first one you see you need time

This way you dont need any time to kill monolites

My english probably not so great:P
I used A/E
