First, the prep, you will need (or so far that i know)
*Mage
*Warlock who will SS you
*Ilag or Winlag (links:http://www.mmowned.com/forums/bots-p...ing-piggy.html // http://www.mmowned.com/forums/bots-p...ing-piggy.html
*Wall-jumping skillz
Ok, so now that we're ready to go, lets begin, first when you get in, stand here
About 11 jumps more DIRECTLY UP and you'll be here
Now we're at this nifty ledge, jump three more times...
and you can BLINK THROUGH! TA-DA! your inside ZA! (At this time i do not know if you can jump inside, if someone would test and try i'd be greateful)
Now, activate slowfall and invisibility and once you become invisible ACTIVATE ILAG/WINLAG! you will then (if you did it enough/strong enough) have pretty much infinite invisability - you know what this means right? go right through and waltz your way into Halazzi's room (door wont be there if your not saved) and go by the vase where the epics are at the top-left corner.
Now deactivate Ilag/winlag - and you SHOULD die by the vase, just use the soulstone and loot, and theres your free epics! - you can also use this to exploit more dungeons and stuff - so go wild!
EDIT:VASE APPARENTLY ISNT LOOTABLE IF YOU HAVNT KILLED HALAZZI! - the rest of this feel free to exploit as much as you want, but you wont be able to loot the vase for the epics
