getting close to dark 7

i'm hardly to kill the dragon without bonus ATK
Ouch look at that def
I mean like a few attacks and it's game over xD
but hey attack is still very important because in later stages for example if u have high attack such as one shot kill then if u r def is low is okay because all u have to do is not get attacked by enemy which skills make it a whole lot easier
BTW I'm in dark 2-2 currently and with my current stats it's nearly impossible to make further progress
i made it,. damnt this dragon is not a joke. now dark 7
i made it,. not easy to kill the dragon and the company but can beat them,. now dark-7
why? u have lightning sword right?
seriously?? -20% at the begining
:(
