Would think that Dryden family crypt would be a better farm spot for skellies than Dead girl....just break everything as you go and leave a trail of bb/firewall behind as you go...with the occasional fireball/acid blast/etc. to clear more out

On high level character can get a few hundred in about 5-7 minutes using this method
...or take a group and really clean up in a few minutes

ran through solo with monk(25) not on GOF, so no burst damage...12 minutes, 246 kills...about 15 of which were not skellies...will come back and edit again after switching to gof and using burst dmg...but everything else but iron defenders is also in MM, so even extra kills worth it

about 7 minutes doing burst damage...269 kills this time, could have been more...but no knock or rogue hireling for the treasure room

and all solo, so seems to me to be best spot to farm skellies, esp with a group...as long as you don't read the sarcophagus at the end can just reset repeat as long as you want
