The module hasn't been unlocked yet so we're going to have to wait. However you CAN still edit your saved games after a certain amount of hours though you won't be able to see the new stuff in the expansion.
theres already a mod that allows the dlc items back into the expansion. um..the toolset allows you to edit your DAO characters, ive tried the thing in the expansion and it errors out. i must be missing a patch or something for the toolset. its easy enough to just raise my stats to the cheating level using a DAO char, then import him/her into the expansion. 900's on all my stats makes for some awesome fights ..and one hit wonders.
