I recommend vio, will. atk,atk, crdmg is fine Using nem could be interesting. His cri rate needs to be maxed out, so if you build with viowill, you can use blade if that is difficult I recommend to use CD+ as more enemy HP, ATK+prop lost HP, or any other option that increases damage. The options on the right should be options that enhance crdmg as well. Prioritize statuses in order of atk, crdmg, cri rate, speed, res, hp, def, acc Aim for +2k in the end Anyway, the higher the atk, the better Same as atk, the higher the better Aim for 200%. Third priority, but always set it to 100%. If you make a mistake at a critical moment, you are more likely to lose. Actually, speed is also very important. I have seen many players' speed in belial, and many of them are slow in his speed. If you can give a def break to the enemy before he moves, you can easily defeat him with his skill2. But if his speed is too slow, the enemy monster is likely to move first, so the def break will be removed. For example, I adjust the speed difference between feng yan, mo long and belial so that there is not much difference between them. I think he can be used anywhere except cc team If the enemy is a cc team, you need to use other monsters. You need to counter and stop the enemy, which he can't do It's effective against top tier monsters like vanessa, camilla, miles, etc. To use him, you need to have other monsters with high durability. If no other monsters are killed, he can revive and use his skill2 as many times as he wants. Otherwise, it's not recommended to use him for your team
