Oh and beam, before I unlocked whm I had less than 800mind (forget the exact number) and roughly 100 less hp and mp respectively. I grinded ARC from 8 to 15. Flipped too CNJ, ported to gridania, accepted the whm quest. Ported too (whatever shroud) then realized I had more HP-MP-Mind. And yeah, after unlocking whm it gave it another boost.
