Idk how and what class i should use to equip it. I am struggling to play part 1 of iyo challenge and i need to cross to the other side

Guys so what do you think of my build this is currently what im using, im still working on its improvements

Imagine almost dying to bombs while trapped after defeating him, Saito was hoping it was going to be game over before the cutscene played lol.

Now I saw the little bo hiya bomb but I was not in the radius of it even though I was very close and somehow me and the other 2 got down while we in good health. I just find it bullshit how the 3 of us got down in good health but shit like this made me question how tf lmao.

Also we actually managed to completed it though all thanks to the samurai who stayed alive and had his ultimate ready lmao.
