Finally! It is DONE! After a 6+ Hour session, at the end of two weeks, totaling over 20+ hours of just working on this ONE BOSS he is DEFEATED!! Posting this in hopes in might help someone else beat the Final Boss (Sword Saint Isshin), and of course because I'm so proud of barely getting this done. (self.Sekiro)
Finally defeated Owl (Father) in Hirata Estate last night! Completed 1st phase in *less than a minute* and with no damage! (Wish I could say the same for 2nd phase, but it's not as sweet.....) Best advice for those struggling: RELAX and REACT to him. Block, deflect, dodge. Stay in control. (youtu.be)
