For that then
I still can not figure out how to boost BP through use of Cheat Engine, I seriously need help on this.
Eh, I wasn't intending for either ran or yukari to goto slot 1, that's crazy (unless you're fighting something like the final boss with first add dead).
As for why you spend level up bonuses in defensive stats (I always do), it's because of the mechanics of this game. the damage formula is attack MINUS defense. (with numbers and such, but the point is it subtracts). Other games might divide. when you have a divide formula, stacking defense will reduce your damage taken yes, but there is no point in stakcing it to kingdom come because while the first 1000 points might reduce a hit taken from 100 to 50, the 5th 1000 points will only reduce a hit from 100 to something like 80. Kinda like the whole elemental resistance formula in THIS game.
Anyway, when you have a subtraction formula, for pretty much ANY rpg game, defensive stats typically rule. While attack and defense are equally important while you and your enemy take exactly the same amount of damage you both give and receive, defense will make you pull ahead more as you level up. because if you suddenly increase your defense by 50%, you'll take half the damage, and you'll suddenly be 2X stronger than your opponant. However if you added 50% more attack...you only kill your enemy 50% faster, and are only 1.5X stronger...hopefully that makes sense.
If you're super under level, and you take like 20000 damage and only dish out like 500, increasing your damage output by 1000 will make a much larger impact than lowering your damage taken by 1000, but the fact is, generally. in a game like this, if you're taking that much damage, and ealing that much...YOUR ALREADY DEAD >=P
