|With 34/36 offenses, Elincia's offensive stats are identical to Tana's. On top of that, she comes with a unique weapon '"`UNIQ--item-549--QINU`"' that is effectively a superior Brave Sword+, boasting 11 Mt but only dropping the user's Spd by -2 instead, meaning Elincia would be capable of quadruple strikes against many foes.
Elincia's A skill is '"`UNIQ--item-552--QINU`"', as it grants her +4 Atk and Spd when initiating combat. Her defenses wouldn't be compromised unlike with Life and Death, and it grants her the Spd boost she needs to help quadruple strike her opponents, while also boosting the power of each of her strikes. This gives her 53x2 Atk on initiation, and 38 Spd after her weapon's penalty. With a single '"`UNIQ--item-555--QINU`"' boost, that's 59 Atk x2 and 44 Spd instead, or with three '"`UNIQ--item-558--QINU`"', that's 65x2 Atk and 50 Spd. '"`UNIQ--item-561--QINU`"' can be used instead as she comes with it naturally, and it grants an extra +2 Atk than Swift Sparrow, but it doesn't grant her the Spd boost she needs.
'"`UNIQ--item-564--QINU`"' makes for a great B skill on her since she's fairly fragile and doesn't want to get hit, Hit and Run and a '"`UNIQ--item-567--QINU`"' will get her out of range as soon as she gets a kill. There are a large amount of B skill alternatives that can also be used though, including '"`UNIQ--item-570--QINU`"' (Provides utility to engage on an enemy and not come out damaged), '"`UNIQ--item-573--QINU`"' (To prevent enemies like Ike (Brave Heroes) from counterattacking with a special that can KO Elincia), or even '"`UNIQ--item-576--QINU`"' (To quad and take out other Red Swords, many who tend to be speedy).
For her special, like most Brave users, a 3-charge special like '"`UNIQ--item-579--QINU`"' works best. A special like '"`UNIQ--item-582--QINU`"' would always proc on the second round of battle, and since Luna would also proc on the second round of battle, there's really no reason to use Moonbow seeing as how it's simply weaker and doesn't activate more frequently.
'"`UNIQ--item-585--QINU`"' / '"`UNIQ--item-588--QINU`"', and '"`UNIQ--item-591--QINU`"' are all essential to having a flier team up and running. Repo and Draw Back to make sure everyone can move to where they are needed, and '"`UNIQ--item-594--QINU`"' to help the team out. There are few units that can survive a round against an attacking Elincia, additionally Goads are immune to panic, but you may still need other fliers to secure kills once Elincia's turn is over, which is where Goad Fliers will see use. Other C options like '"`UNIQ--item-597--QINU`"' (if the team needs another Hone buffer) or '"`UNIQ--item-600--QINU`"' can also be considered.
The '"`UNIQ--item-603--QINU`"' maximizes her Atk, allowing her to do even more damage with her strikes.
