I was unable to do a data mine for the Dec 6 update due to laptop issues, but that has been partially resolved.. so I thought I'd still put something out.
While this is a few days delayed, here is a limited data mine for the update...
Included are the new mob models, since I don't think anyone else actually covers them.
I will probably include music files later on.
Major spoilers ahead.
New Abyssean mobs
Wings of the Goddess Missions:
Lady Lilith (battle model)
(yes, she looks like Altana)
