Akuoumaru Best Characters

Who is the Akuoumaru Good For?

Diluc	Razor	Beidou
Chongyun	Xinyan	Eula
Dehya

Synergizes Perfectly with Elemental Bursts

Akuoumaru thrives in the usage of Bursts. Hence, characters like Beidou, Eula, and Dehya will benefit largely from this claymore. Taking their Energy costs into account as well, their Elemental Bursts will be able to dish out maximum damage.

More Energy, More Damage

Provided that they are accompanied by party members whose Bursts don't come cheap, characters like Diluc, Chongyun, and Xinyan will benefit from it despite having cheap Energy costs. We recommend characters like Raiden Shogun, Yae Miko, and Xingqiu.
