So I was reading about making money in FFX and Lisa has 2 suggestions both involve the weapon based ability "Gillionaire".
1 option implies to just have Rikku with her Godhand fully upgraded with Gillionaire in your party and kill Mimics. This would gain 500K gil each fight.
Another option implies to have everybody in the pt get gillionaire and than basically do the same.
I have tried the 1st option and got about 10k hardly close to the suggested 500k so I'm sure I'm missing a key piece of info

Some questions:
1- what does gillionaire actually do when successful? Multiply gill with a certain factor or...??
2- does it work just being in the party OR do I need to actually hit the mob with it at least once or even kill it with it?
3- does having multiple gillionaires in a pt multiply the effect or referring to the previous question, just increase my ability to kill the mob with it?
Thanks!
