Camilla skill inheritance

Depends a lot on his boon/bane. Mine is +Def/-Spd, and my target setup is:
-Special: Rainbow / Iceberg (Rainbow procs more frequently thanks to her brave lance, Iceberg deals more damage in a single hit - so if you need higher atk values rainbow is better, for overall damage, rainbow is better)

-A Passive: Fury 3. This gives her very good all round stats and some impressive tanking opportunities - Atk 41, Spd 27, Def 34, Res 34.
-B Passive: Brash assault 3. With relatively low HP and good defenses, as well as the tick damage from fury, she can trigger BA quite fast - while staying durable.
-C Passive: Savage Blow is A-Ok here. It softens nearby enemies and makes them less of a threat.

-Support - either Draw Back or Ardent Sacrifice or Reciprocal Aid would be better, but I'm probably going to end giving her rally attack because it compliments my team better. First one is pure utility, the other two are there to help with Brash assault.

On a neutral or +Atk camilla, Death blow is probably straight up better than Darting Blow, as is the case for most brave weapon users. Drag back is an interesting choice here, due to her being a flyer. Axe breaker can also work here, and let her ORKO or severely wound most axe users on sheer number of attacks (a +Atk, death blow/axebreaker Camilla ORKOs Hector [thanks to procs] and oneshots takumi before he can fight back).

A +Spd Camilla would be the only one where I'd keep her innate Darting blow. With Spd 36 and some buffs, she can wreck a lot of medium-speed targets. It could be complimented with Desperation for lots of attacks. She'd need some help with her damage output, though, and Fury is equally viable for this setup.

You also have the option to trade her brave axe for a hammer+, an emmerald axe+ or even a silver axe+. all of them improve her stats by a large margin - Atk at 42/45 (depending on weapon) and base speed of 32 - which works much better with her darting blow (speed 38/41 depending on boon). On this one I'd go for Desperation - basically, to mimic her original brave weapon. This one isn't a good idea if your Camilla has a -Spd bane, like I do, though.

I think the problem with Camilla is that you have to make a choice between Iote Shield or improving attack for A slot.

If you go for more offense, go for a Klein build. Death Blow for A Slot. Maybe Life and Death since her defenses can take the hit. Vantage for B Slot. Keep Savage Blow. Keep Brave Axe, maybe Luna, Moonbow for Special.

For a defensive build, Iote Shield for A slot (this skill will come from Michalis in the next GHB). Renewal/Seal Attack for B slot. Aegis for Special.
