Help.. how do i make this build better?

You are playing with a coc build... It's not gonna kill boss, no matter what you do, and it's gonna be squishy, no matter what you do. My recomendation to make this build better is: Delete you character and make a new one, a stormbrand hierophant maybe, I dont know, But one thing I can say, coc builds are REALLY BAD at bossing.


If you insist in continue with a coc build, take 1 cospri out, and use a shield instead, it's not god lose too much damage and you are gonna survive more.

By the way, your belt is pretty bad, I get that you are using it for recover, but, the amount of life is too low... get a better one and try to get itens with a little bit more life. I think it would be good to farm maps, but it wont kill bosses anyway

I'm not an expert of CoC ice nova builds, but I'm here to help you.
I would recommend you follow a guide, as coc builds are kind of complicated. Your aps (attack per second) and cooldown recovery speed are not optimal.

Additional comments:
1. Your accuracy is too low. You have only 87% chance to hit. This is a cause of a big DPS loss. You should get accucary from the tree and/or your gear. You should aim for at least 95%, or ideally 100% chance to hit.
2. Because you are using mark of the shaper, your other ring should be an Elder ring, not a shaper one.
3. I'm sorry to say this, but your cluster jewels suck. Don't use them, and take nodes in the standard passive tree.

Hope it helps.
