FF5 advance classes romhack, early dark arts locations?

this has been asked a few times in forums etc, been looking at jeffludwig.com spreadsheet etc without luck

as everyone knows the advance classes were locked too late, this romhack gives them in world one, the creator stated that he modified the rom so u could farm the dark arts earlier, i havent been able to find where or how, just got necro and would love to farm its skills asap

cheers
