i have first hand experience with the public cat dupe and hybrid method(s)
you could dupe runes/tokens/gems and grey items along with whites. you had to cube hrs into a perm hr before leaving the game using a duped gem or it would poof. the gem was perm after the dupe so it was really useful for mass rolling of ilvl 99 gcs, soj diadem rerolling, hybrids
what you could not dupe as it poofs on exit of the game:
rares
magics
uniques
there was zero ways to perm out if you had a duped soj or shako it simply poofed if you used cat dupe if you left the game. if the zbug helm was duped it used another method before cat dupe.
it doesnt matter your in the wrong forum and this is not helping anyone. your fg is lost
move on and learn and be able to take losses.
