I decided to kind of build my Siegbert on my own. Since he has a combination of Swift Sparrow 2 (Dark Greatsword) and Death Blow 3, I upgraded my Heavy Blade seal all the way to 3 and put it in his S slot. I gave him Swordbreaker 3 so that he can double and deal with sword units. I inherited Galeforce from my Cordelia to Siegbert so that he can almost always make another move thanks to Heavy Blade 3.
In my opinion, he's basically Brave Roy but even better thanks to his high Atk and Spd.
What do you all think?
Quite good as you have him now. I would prefer a second swift sparrow because he's in that range where every point of speed will score extra doubles.
Can he survive two counterattacks? If not then desperation might be in order, though it must be said that swordbreaker really is a strong choice here.
Swift Sparrow 2 and Desperation 3 would be perfect for Siegbert. If I got another 4 star Shanna, Desperation 3 is good but Swift Sparrow 2 is quite limited, since I only have Brave Lyn and Ishtar who have them and I don't want to get rid of either of them.
(Also funny thing is I keep getting Siegberts from non-focus units which is quite funny.)
I think it's a really solid build for him. I run a similar build on my Siegbert with Swift Sparrow and Desperation, which I'd highly recommend. What kind of team do you run him on? I think Galeforce is only really good if he's on a team with either horse buffs or tactic buffs, specifically Atk and Spd Tactics. Otherwise I think Galeforce is a nice choice, but damage specials like Draconic Aura or Bonfire pair well with Heavy Blade when he isn't getting strong team buffs.
Edit: I'd say Desperation is especially good on your Siegbert since he's -Def, so it might be helpful if he can avoid counterattacks.
He is indeed -Def but Galeforce is a 5 cooldown special, and with Heavy Blade 3 this would obviously occur.
Siegbert attacks (5 to 3)
Foe counterattacks (3 to 2)
Siegbert follow-ups (2 to Activates)
The thing is, I wouldn't exactly know if Desperation could be good with Galeforce since if Siegbert were to attack twice in a row and ends up defeating the foe, the cooldown would still be at 1, thus not activating Galeforce. Other than that, you make a great point.
Plus Swift Sparrow 2 is very limited to me since I only have Ishtar and Brave Lyn. I really wish I could give it to Siegbert though.
Also about what team I put him in, I would usually pair him up with Serra, Clair, and Gunnthra based on Blessings I've given (I don't know why I gave Siegbert a Wind Blessing out of all things, which was a mistake.)
This is a point that needs to be noted about 1-turn galeforce builds. If you're not using slaying weapon, you need either QP (in which case you will have to sacrifice your A-slot unless your weapon has a cooldown accelerator like B.Roy or Caeda/Clair, or infantry rush is available) or Ostia's Pulse/infantry pulse. HOWEVER, once galeforce activates the first time, if you attack a second opponent, you expect to start your second attacking turn with only 1 more charge to activate galeforce again. If you retreat, yes desperation can work against you unless dance/sing is available. But if you just take out another opponent, you can expect to activate galeforce over, and over, and over again.
