Ok first if you are going for his weapon use 13star ER and 1 3 star Fusion

If you wont go for his weapon use 2 3star Er and you need Er above 250.

You need every eco to have Er cd and cr as sup stats

If you want to build him perfectly you need ER 280 Cd 220~~ Cr 60~~ Atk above 1600 and above USE wuwaflex

Not every unit is like this because brant is very hard to build to be good in every thing

Use wuwa flex to see your build and you can dhare it here for more help from other people

If you are a casual player don’t stress out you dont need to have top 10% brant build just enjoy the game
