Can someone explain the mechanics of DC, MC, MR, AC, SC, pl0x

Hey, well I know that

DC = Warrior attack power,
MC = Wizzy attack power,
SC = Taoist attack power,

AC = Physical Defence,
MR = Magical Defence,

but each thing has two numbers ==> x-X
I'm just guessing but is it min dmg vs max dmg? because it really doesn't seem like that.

or maybe it's first number multiply the second number = damage and second number = the amount of sc needed to damage the monster? i unno >_<

what do each number represent?
is it better to have x-X <== higher / more important than this ==> X-x

its better to x-X
with X-x x is the hightest it can get
with x-X it varies from x to X
take dc
x is the lowest possible hit u can do with a normal attack
X is the hightest possible hit u can do with a normal attack
ac/mr is the reduceed damage, x-X is the best
if ur base ac is highter than ur max ac u get 1 standard damage decrease
as for sc/mc
the damage varies from x to X * the damage multiplier the skill itself got

the closer x and X are to each other, the stabler ur damage/defence is
the further the x and X are, the more ur damage/defence varies

thts bout it i guess

well said there mass
