Hello everyone! While trying to create my set up for NG+, I went ahead and tried to crack the power formula... and I foud out about it!

Total power=(personal power+weapon/chain power)¤personal power/10

Pretty sure defense works the same.

So since personal power is both based damage and the multiplier, it's more than likely what you should focus on while making your file set up (aka 7 bulkward brand). Still going to run some charts to test all that anyway.
