I had a +atk -def one, but I ended up merging him into my +res -def one (who then got merged into my +spd -def one) since tanking magic is more of his niche. His atk is going to be bad regardless of the boon or not, so his damage is mostly coming from iceberg/glacies
i'm sure they'll release another unit with def ploy eventually, but idk about summer gaius. they'll probably keep that weapon exclusive to him and it's possible that they'll bring back the seasonal units each year. but imo, just hold on to your summer gaius for the time being, but if you really want zero to have the refreshing bolt or def ploy, then go ahead and do it
i think i have a +atk felicia somewhere. i should check ha IVs and see
edit: yeah, i have a +atk -hp and a +spd -res felicia. maybe i'll build up felicia once celica is on another banner. i even have an extra summer frederick that i could use to give her seashell+
Ye +SPD made more sense I suppose. With +ATK that gives him 4 more DMG to tack on to his nuke, whereas +RES would only give him 1.5 more DMG. But he probably gets more done with +SPD.
Felicia gets more done with a Poison Dagger+, tbh. That's still the only saving grace of dagger users so far until they make an anti-horse or anti-fly-gorl type of dagger. She's too weak to do anything to the likes of armor users, but she can chip away at magic users super easy. Especially with Iceberg or Glacies backing her up.
My Felicia:
Poison Dagger+
Iceberg
Fury 3
B Passive:
Cancel Affinity - chips at the bulky mages that rely on Raven Tomes before dying (also makes it harder for Felicia to die to them)
Poison Strike 3 - chip chip chip when she outlives her usefulness as an infantry killer
Quick Riposte 2/3 - classic guaranteed double hit when baiting
Xbreaker - if she is super specialized to take down popular tome users like Nino or Tharja (meh)
Escape Route/Wings of Mercy - teleport shenanigans can be fun I guess
C Passive:
Any hone - for team buff and support (easiest to utilize)
Breath of Life - for healing while dealing chip damage (with Seal for +10 HP each go)
Savage Blow - for AoE chip damage support
Any Ploy that relies on RES - 38 res I mean c'mon gorlsss
Spurs - probably the least effective use of her stuff tbh
I wish I had Distant Defense but I think I'll wait for someone that's not 5* Locked to put that on Felicia. I think she gets more out of Fury 3 anyway, or perhaps just +2 RES/SPD or +2 RES/ATK or any of those weird combo ones. Even though her attack is low, having that 1.5x damage tacked on is ridiculous unless the person has HIIIIIGH DEF. Especially since she's basically guaranteed to double with 44 SPD (Fury 3, Hone SPD, JAJAJAJA).
