I'm not a programmer and know somewhat what .DAT mining means. Is there a place that lists all the hidden abilities and spells that players haven't gotten acces to? If not, please post here.
I've heard rumors of Dia V's, diaga II, and whatnot. Please list actual files not imaginary ones.
As an aside, if there are mob abilities please feel free to list those, but mark them as such to the best of your knowledge.
.DAT files are the pieces of data that the systems uses to play FFXI. Some people have programs that read these files and can tell what information is stored for FFXI to run.
There are no such spells actually "in the game" anymore.
There some reminants of old string tables left in the dats for stuff that has been removed, but since newer spells aren't in that list, you can tell the game isn't using it.
Many spells were "in the game" as could be determined by using /recast "spell name" to see if it existed. However any spell for which that worked was effectively removed in an update. Some of these spells were re-added later (e.g. pro/shell V)
Basically every other spell in the dats is a spell used by monsters that isn't available to players.
