The bicheon force series

[Zycor]

the bicheon force shilds, aka that one shild skill that lowers defence for attack, has a messed up description. at least i think oO

i've tested it out with different shilds, and the stronger the shild, the more defense u lose and attack gained. But you don't gain the set points like it says. Book 3, level 2, gave a blader 144 attack power with a 72 +3 shild. book 4 lvl 1 description says it only gives 107 attack power.

how am i suppose to know how much attack power im going to get oO

and the defense drop, its not an overall defense drop, im thinking it only drops the defense of the shild by that percent. any knowledge concerning this?
