Final Fantasy Hacktics

1. If I set the multiplayer items as non rare will the enemies use them?
2. If I give some job to equip something example i give thief to equip crossbow, will the enemies use them too?
3. If I repatch the game, the save file will still compatible with previous patch?
4. I set some of the assassin abilities to be learnable with jp, will the assassins still learn it when I fight them?
5 Same thing but it's about lucavi skills. Is lucavi count as monster? So they will learn all abilities they have even they have jp cost?
