Brant Build

Brant's signature and by far best weapon. The massive Energy Regen, Basic ATK DMG and small CRIT Rate boosts the weapon offers are all Brant's top stats, allowing him to sport the Tidebreaking Courage set comfortably, even with a Fusion DMG Bonus Echo if you build his Energy Regen well. However, this sword isn't good on anyone else, only pull it if you have Brant, and if you do pull it, know you'll only use it on him.

ATK and Energy Regen stat-stick much like Aero Rover's Signature weapon. Only marginally better than it as it can provide 12% extra ATK via the passive, but generally not worth sparing the pulls when Bloodpact's Pledge is free to obtain.

Aero Rover's Signature weapon is actually very much usable on Brant with Tidebreaking Courage thanks to its high Base ATK and Energy Regen main stat. Unfortunately he is unable to make use of this weapon's passive effects, but as a Base ATK and Energy Regen stat-stick it's his best F2P weapon choice assuming you can acommodate Tideebreaking Courage's steep build requirements.

Camellya's signature weapon is usable by all Basic Attack focused Sword wielding characters, including Brant, but it is designed with her in mind due to a lot of its power locked behind spending Concerto mid-rotation, something only Camellya can do. While Brant is able to make good leverage of most of its stats, but due to being unable to benefit from the Tidebreaking Courage set and not benefitting from the complete passive effect, it ranks lower than the above options.

The combination of Energy Regen, CRIT Rate and solid Base ATK make this weapon usable on Brant, and while its small ATK% boost is also easy to stack up once, Brant doesn't get to make use of the second stack in his rotations. Unfortunately, unless this weapon is R5 it's not possible to use the Tidebreaking Courage set using it which makes it rank lower than above options.
