use light element more

Just keep dodging right

also focus on getting weapons and leveling your skills so you can do more damage. (having a healer helped me).

if you have good enough characters and equips. then all left is just git gud. (simple : learn enemy atk pattern.)

My best tip would be to learn his atk patterns and dodge them effectively, Leveling up your break skills and ofc light elements hero or weapons. I know this is basic and blah blah blah but once u get the pattern of his atk it will be much more easier, but try to get a little over the recommended team power even 100 will do.

increase your total power 50,000 or above should be enough to make him a cry baby🤭

I had to get stronger before taking him down and manual play I even reset the stats to focus on strength and precision to focus on max damage. with shadow step as much as possible to lower his defense

its hard bruh, jinwoo is suck, he need full support...
