atma farming should have 3 other options to get them.

1st just keep the fate ways.

2nd dungeons runs clears should get a chance to get one.

3rd way if duty roulette and that job needed for the roulette you get a 50% chance of getting one.

Extra credit :Tanks after they get theres' will still get a chance of getting one at 20% for the other jobs in the group on the duty roulette or one for there other jobs.

You would of hated 11's lottery spawns then

Third one if pretty dumb.

You forgot to add a fourth one : Every time you log in there is a 70% chance it will appear in your moogle mail.
