You'll face a lot of backtrack without experience. Go first just as a trial, and if you can defeat at a single shot without experience, the game is yours mate! Try intercepting him a lot at first. Then make sure to not gain the blunders. Dex his sp1 and hit him when stunned and don't stop until the wounded timer runs out. On my second run, i could bring him down to 68 percent of health, but i struggled after that. And I just quit story content, lmao. I will hit him back stronger tho. Best of luck, this one will make you pull up your socks, for sure. Also, the path you choose matters! I kept taking the cosmic path, thinking it to be easier.....for me the inflation path turned out to be the most accomodative. Find your path too.
