how to get eldritch blade on my blade bound magus

[alternis sol]

I'm asking this for a character i'm going to start playing here soon hopefully. specifically i want the character to have 5 lvls of bladebound kensai then 2 lvl brawler after that i'm thinking of switching to either blade adept arcanist (which brings up the question how do bladebound and blade adept stack anyways.) or feral hunter for darkvision on call and lead blades + a couple other situation spells.

exploit in question
Eldritch Blade: A blade adept with this exploit uses her
caster level instead of her class level for the purpose of
advancing her bonded sword’s powers.

You can't do it without taking, at least, 5 levels of Arcanist. Also, you'll have diluted the ability by a lot, since your caster levels don't stack.

P.S. Is your name a reference to Bravely Default?

well that stinks guess i'll stick with feral hunter than, was hoping to increase the black blade's lvl some more.

and yes it is haven't quite finished beating the came due to annoying as hell last stage side missions (paraline and quadra should not be on the same enemy squad,)

Is this for a home game? If so ask your GM if you can take the Exploit as a Magus Arcana.

sadly no this is for society
