well I just finished Kikoku :)
I think it was best stated previously. It was an accomplishment for me as a career ninja as ninja was the FIRST JOB to be lvl 75 and such.
However, in terms of usefulness?
1. I hate the magian trials.. it is boring as hell...
2. blade: metsu looks cool/sounds awesome/Sucks balls in dmg
3. Kikoku offhand is just awful.. no additional stats... no paralyze no triple proc no nothing.... so.. yeah...
However, I do believe that sometime in the future they MAY upgrade kikoku a bit more to be stronger and also... I don't have lvl 90 Kikoku yet but I'm thinking it could be competitive to Kannagi inside or outside if you are using Blade: jin.
HOWEVER!!!!!! triple proc never EVER happens... unlike Kannagi's aftermath... so...
what everyone is saying is very true.. kannagi is stronger but... :) if you love ninja why not?
It's not like you need gil for anything else atm~
get em before the bynes price goes through the roof... I saved up 36~ 37 mil before the dynamis update to finish my Kikoku and then.. update happened... bynes price sky rocketted so just finished.. but I AM FINISHED!
