I don't understand people who sabotage their own situation, which creates frustration, and then rage-quit the game. Like, okay, whatever I guess... :S just really weird to me.
Valtr or not, though, I have to say... 150 tries, really? :\ I don't want to judge, I mean there are some optional bosses in Nioh I must have retried close to 40-50 times myself, but that seems excessive... why not, say, post a video of your best attempt and ask for tips on how to improve? Why not watch youtube videos to see how other players handle it? Or ask for build advice? Etc.
If you are struggling people are willing to help, but say "I tried 150 times, fuck this, I'm getting rid of the game I otherwise enjoyed" is a little baffling.
