some questions about learning on hit and jobs skillset

[zend]

1. does learn on hit need to be hit not miss? Example I would like to add Mindblast and blaster to learnable skill. That skill inflicts disabling stat to the character so it will not learn when hit, but if it missed will I learn it?

2. Can I add skills to Calculators and Geomancer? I would like to add some monster skills and make them learnable to them

3 Can we learn monster skill from monster crystal if I set it to some jobs? Example I set Dancer or Bard to learn Blaster or Mind blast or Vampire from vampire cat then can they learn the skills from the monster's crystal?

No to both. The ability needs to actually change something about your character to allow you to learn it. And you can't simply add abilities to skillsets that don't have [Default] Action Menus.
