Okay I have to admit, this one did actually make me laugh.
They're always after me lucky charms...
Jokes aside, perhaps it is a hint? geomancer, oracle, green mage, etc
Job trainer: Warwick Davis.
Probably would be Green mage, but not the green mage from tactics, since that one is pure buffer / debuffer, a job that will not work in this game. So will be a totally new implementation if that's the case.
