mediator is funny because the whole “white mage” job tree is largely useless (priest is straight worse than chemist in 95% of circumstances and oracle is just crappier beowulf) but then you get all the way to mediator and you can use a gun again
you do need a mediator at some point to get the bears that you have to breed for poaching if you want ribbons (but honestly meliadoul and cloud are better with twist headbands)
