Does anyone have any suggested units or builds? I didn't see anything terribly inspiring on the site and I have a winter Robin and a couple of Ares copies ready to fodder. I have both slots (sword cavalry and blue armor) fairly well covered, so they go into the fodder pile.
They're great on duelist units, who have decent to high attack and/or spd but also come with decent defenses to take a hit and tango with the opposing unit. Bonus points if said units come with other HP threshold B-skills like Vantage, Wrath, or Desperation. They can be your initial bruiser who becomes a sweeper when they reach that HP threshold.
Many units, like Beruka, can make use of Brazen skills. Tanks can make use of Brazen Def/Res (I know my Donnel would appreciate it to be a more specialized melee unit).
...Too many other people to name. A lot of units can make it work, it's just that most people prefer to use something less expensive.
If you don't mind not getting the boost on the first round of combat, Brazen Atk/Spd is a straight upgrade to L&D. So any glass cannon unit loves it, premier pick imo is Raven because +12 to offenses and just -5 to defenses is very nice.
Braven Atk/Def is more niche in applicablity. Best unit for it imo is Nephenee; she's really fast as is and the extra defense helps her tank during combat so she can land another wrath boosted Moonbow
