So basically this bug stacks sieg's rage damage increase.
You must have unlocked the 2nd weapon slot in order to use this bug.
Here's the way :
1.activate sieg's rage
2.when in rage mode, quickly switch your weapon
3.your rage mode will end but the damage increase will be kept
4.repeat this step to stack the damage
This bug not only increase sieg's attack but also defense (as the rage mode do). I'm able to reach 4k damage per hit using this bug. I'll post the image later.
Note:don't overdo it since the system will detect you as cheating if you make your stats too high
EDIT :
as Aug 31, this bug has been patched. Its no longer work. Thanks
