Uh. Rucksacks only add +10 All Stats. You want +20~30 stats to be available through boot cards? That's a little too much when it comes to certain classes, even if it's replacing a FBH slot. It needs to be competitive with Dragoon Wizard, which adds HP and SP. Maybe increase the chance to cast KE to 15~20% with at least 99 base INT be reasonable, or adding +20 int for mage/acolyte type classes sounded nice. Atroce Card being +100 Base Attack for Whitesmith Class only sounds nice to me.
