screamers on mt nibel for power sourcess

Just a question… does anyone here no if screamer is supposed to be a rarre enemy because I seem to encounter them about once every 20 or so battles….wich kinda is a big kick in the ass because I’m trying to max out my strenght on my 3 main characters an so far I fought them twice an got 200 power sources…(yes I’m using w item glitch) but 2 encounters every 40 battles is insane…there doesn’t seem to be a more efficient way….is the special battle at golden saucer any easier ? I was told u can morph enemies in the special battle?

Morph Heavy Tank from Gongaga into a Power Source, or wait until you get to Sunken Gelnika Airplane and morph Unknown 1 into a Power Source. I don’t think there is an enemy in the Battle Square that can be morphed into a power source.

Yeah I was in gelinka only 1enemy at a time can’t use the w item trick…but I googled all the info I need thanks anyways for the help tho.
