Need prison of elders run for elder cipher

Hey guys, im looking to do some prison of elders runs tomorrow night as my lvl 34 titan, I've got max gally and multiple 365's, I have my second elder cipher and need to clear the boss part then hopefully once I've done this one I can do a 35 before the wipe and get the next one started :-D any help would be greatly appreciated.
