So I'm about to begin the twin boss fight on hard as I think merciless is too intense for me. Now I think I'm absolutely f**ked as I just strengthened my Yoshitune randomly without knowing I can completely max a few of his stats. Can anyone tell me if I can take on the twins with Yoshitune at the current stats that I have on hard? Stats: strength 75, magic 57, endurance 64, agility 68, and luck 55 all have been increased by 3 thanks to arm pc accessory, but I plan to itemize crystal skull soon.
Note: Also I'm going to post other questions for the battle in the comments of this post.
