Your current build Project?

I'm building Soleil but for arena purposes for Max points so it's not a practical build.
If not for Arena then my build for her is a quad build.
Brave sword+
Luna
LnD
Desperation
C skill is flexible
+atk/spd seal.

Another is.
Slaying edge+(spd)
Blazing/Growing wind
LnD or Swift sparrow(currently LnD)
Desperation
C skill is flexible
Heavy blade.
(AOE specials are underrated, she killed so many enemy units even effie with Wary fighter cause Wary fighter does not matter when Special proc)

Well, I have a few projects, but I can't do most of them due to a lack of supplies.

However, I'm working on my Canas who's almost complete. Just need Iceberg learned and the merge.

Still building my the same one as always... Hawkeye. Nearly got him to +10 with my desired IVs. I took panic ploy off him in favor of running vantage in the B slot. C slot has Spur Def/Res 2 from a 4* Morgan that he ate. Not perfect but he's good enough.

Once I get my 11th one I'll move on. Seems like I've been waiting forever.

Been building a few people over the month and I'm currently almost completey out of fodder, so building stuff isn't really an option right now. I do have the resources for a Seliph I wanna build, but lack the feathers to actually promote him.
Divine Tyrfing
Reposition
Aether

Warding Breath
Dull Ranged
Panic Ploy

Deflect Magic

Want to make him a mini Sigurd (as I never got a regular Sigurd) and just have him eat up magic attacks. The Seliph I plan on doing this with is completely neutral, though I always have the option for a +Def/-Spd one, which, honestly, isn't a bad option either (I'd prefer if his boon were Res though). I'd just need the feathers (around 80k~ for Aether, Dull Ranged, and Panic Ploy, and promotion) as I already have most of this fodder available.

Also, I recently started on my first serious +10 project, who'll be a Klein. He's at +2 rn (and Summoner Supported) because colorless hell is a thing and this game seems to love giving me Saizos.

I've got 220k feathers ready to go for Sheena once I pull a few more copies. Regretting that 4*+10 one a bit lol. I didn't really want to, but it's the only option I have to increase my arena and arena assault scoring. :(

I have a lot of build projects I either lack the information or the fodder to complete. For example:
TA+raven Cecilia needs a special
Ryoma gets glimmer + vantage when I pull a 4* Lonqu (building him for OHKOs because I have a glass cannon IV, +atk -def)
Alfonse gets brazen atk/def when I pull 4* Ares
Sharena gets atk/spd bond when I pull it or if I have someone to take LA Lyn's place (currently don't have another 5* blue armour)
Bunch of healers without A-skills, some 4* merging, some 5*

Some build projects won't get completed until my first four +10 merges are complete, ex: brave axe Cherche, pain+ healers

Hmmm at the moment no one,I'm just amassing feathers until someone piques my interest.

Marth & Felicia

Have feathers...but need to pull some copies of the units.

I have a few in progress.

Recently got the Desperation skill I needed for my Sothe. I'll promote him once I have the feathers.

Meanwhile, I have 4* supermerge units that need a spare of them promoted to give them the 5* weapon.

As for others, still on the lookout for skills to give Celica... Renewal being one of them. In addition, Ishtar will be needing Desperation.

Recently got a better IV Fir (last one was cursed with -atk), so I could work on getting her Nameless Blade.

For 5* supermerge projects, I need one more Soren to finish him up, then I can maybe shift focus to L'Arachel.

I have 4 merge projects:

Gwendolyn ( currently +7 )

Berkut's Lance+ (Res)
Swap
Aether
DC
QR ( hoping I get VF )
Atk Tactic
DD

Sophia (no merges)

OwlTome (Def)
Drawback
Aether
CC
QR
Res Smoke
Res Tactic

Kagero (no merges)

Barb Shuriken (hoping for Starfish+)
Reposition
Iceberg
Brazen Atk/Spd
Chill Spd
Atk Smoke (hoping for Atk Wave or Spd Tactic)
Flashing Blade

Camilla (currently +2)

Slaying Hammer (Spd)
Reposition
Iceberg
Fury
Desperation
Def Ploy
Guidance/ Def Tactic

Hoping I finish Gwendolyn and Sophia. I don't have that much copies of Kagero and Camilla.

If only she would quit sending her sister over... And bring along a +Res(-HP) IV.

Here's what I'm currently working towards. Already got the IVs, just waiting for Wrath and another Ares and one more copy of Roy. Just farming feathers in the meantime.

I am working on a couple different projects, personally.
1st project; Genny, I just need one last merge.
2nd project; Olivia. I need 3 merges, Kadomatsu+, and one merge needs to be +Atk -HP IV's. I'm running Aether/DC/Chill Speed/Attack Tactic/Drive Attack for pretty much a pure support build, to complement the colorless mage that is my first project.

I did just finish my 'third' project (third in priority, but I ended up having the merges/feathers before the others) which was an Owltome/CC M!Robin. I just need a dual rally and Aether on him and he'll be completely complete.

Working on my Chrom uberTank build with refined Falchion, double close Defense, and guard. He is nigh unkillable on a defensive tile. Just need a few more merges.

Two projects right now :

Roy +5 +def / -HP
Full on tank
Binding ( +eff )
Dual rally
Ignis
SB / Sword breaker / Atk smoke / CD seal

Corrin F
Debuffer
Dark breath ( + Spd )
Dual rally
Luna
DC / Windsweep / Savage blow / Phantom speed

Looking into changing the Blow and phantom speed, maybe a res smoke ( but god that's expensive ) and a DD or QR seal

Looking for a mage check to complete a core, probably going for Soren or Kaze as advised by Sir of coffee and seeker ( credit where credit is due :) )
But if anyone as another idea i'm always open :-)

Fae +6 Currently done with her standard SB LB build and IP. +def -hp
Effie+8 Slaying Spear Mirror strikre Wary Fighter Odd attack wave +res -spd

I have, like, a billion of them for different purposes:

I'm looking to build up a fully-merged Armor core of Effie, Draug, and Sheena so that I can eventually score in the Top 1K of Arena Assault (top priority). Effie is +9, Draug is sitting at 5 copies (no merges yet), and Sheena has only one.

For units that I like and want to +10, I have Marth +1 (3 extra copies), Catria +1 (3 extra copies), Lukas (8 copies), Fae +7 (one extra), A!Tiki (8 copies), Lilina +1 (two extra), Priscilla +1 (one extra), and Sakura (two copies).

Then, for units that I don't plan on max-merging but want to bring to 5-Star rarity for the other in-game content, such as all of the GHB units I haven't promoted yet, Masked Marth, Caeda, Clair, Cherche, Raven, Soleil, Ares, Chrom, Klein, and some other's that I can't remember of the top of my head, but already have marked as favorites so that I remember to build them.

(I know that I have a ton of units that I want to build, and that it would be wise to drop a ton of them, but I can't drop them because I like them all too much to disrespect them like that. >.<)
