Invitation question

[scartyxcat]

So I've been playing the original FFT game and decided to try 1.3 but i got a question related to the  " Invitation " skill of the mediator.

I saw some video of Deep Dungeon and I was wondering if you could actually invite anything found in there? arc knight/assasin/ etc... or is the invitation  the same as the original game which is everything except (boss type/class that you can't change to)  enemi.

1 more little question ^^ where can we find " gained jp up " abilitie now? its not in squire so...because in the job changes section there's nothing that mention that it has been changed to another job etc

Most of the dd baddies are immune to invite.  If some are not, then they're basically generics in the first place and not worth inviting (delta earth squad?)

Gained jp up is removed.  All jp costs have been lowered to compensate, but now you're free to equipn a real support function
