From the FEHereos In-game news. Original post here.
You can deepen bonds between Heroes through Ally Support. Support can be set for pairs of Heroes in the Advanced Growth menu. Deploy pairs of Heroes into a battle with enemies level 35 or higher to build their Support Rank from C to S.
When two Heroes who support each other are nearby during battle, they will receive a stat boost. Heroes will receive different boost effects depending on whether they are adjacent to each other or separated by one space.
You can choose to honor the relationships between Heroes from throughout the series or build relationships between Heroes that work well together on the battlefield. It's your choice!
Ally Support pairings can be changed at will. However, if you build the Support Rank between two Heroes up and then switch one of the Heroes to another pairing, the Support Rank for the initial pair will be reset to C.
You can create multiple Ally Support pairs. However, each Hero can have only one active support pairing at a time.
Multiple identical versions of a Hero cannot each have separate support pairings.
Identical heroes cannot support each other.
All characters can be supported, there are no restrictions.
Support rank increases only when battling enemies of level 35 or higher.
Jaffar isn't the strongest of units on his own, but give him Desperation, Fury, the summoner support, and have a tanky(ish) dancer to not only block other melee units but to give him a second action? He will literally kill everything in the game that doesn't have vantage and a high attack. Not even TA-Raven units can survive him without vantage.
Nidhogg Innes and CC Gronowl Boey. If they stand next to each other both their stats will be multiplied by 2 through their weapon effects + the support pair buffs + spur def/res all of which will stack with each other effectively turning them into magical and physical tanks respectively. For this pair, positioning is super important.
Thrown in Eirika w/fortify res seal for quad buffs (assuming she has rally res for an assit skill) and Lancina with spur def seal (can go on the other two if preferred) for more spur buff stacking and you effectively turning them both into walls and nukes. Just be careful with panic ploys and where Eirika is placed. Also as said before positioning is very important, if using these two units along side Innes and Boey.
The duos (Eirika and Lancina support) also work pretty well in the current meta as well with Boey (w/bowbreaker) meant to counter B! Lyn and Innes meant to counter Reinhardt.
As for glaring weakness this duo is very susceptible to sword units especially the ones with DC. To help fix this just bring strong blue units like Lancina or units with sword breaker.
Wellll, BoL 3 and BoL seal gives 15 hp and also her stat spread including Summoner support is 50/42/26/48/37 making her nearly impossible to kill and can even tank some red mages :D and ez heals with linde and just kill all those pesky red units
Do you love our blue haired husbando as much as I do? Do you have a brave Lucina taking up space? Slap these bad boys together and get ready for god to become more godly. Summoner support on hector improves his hp and defenses, and support with lucina serves as a soft fury. add on the ability to grant hector +6 attack and +3 speed and cover all his bad red unit matchups and this bad boy will devour anything without a ruby sword+ or raorblade+
Hector and Effie are the two best knight units in the game, and both are really tanky. Hector with pivot will always stay near Effie and she can protect him from strong red units with her brave lance+, while hector helps against strong green units. Hector's Goad armor also has perfect synergy with this, making Effie's wary fighter more effective and thus, making them harder to kill.
These two have a pretty cool relationship in Fates, and also work well together on the battlefield. Azura can buff a neutral-speed Fury Ryoma's speed to 40 and his attack, with Hone Atk, to 59. With the support bonuses and a Hone Atk, a neutral Fury Ryoma can gain a stat spread of 41/59/40/32/26, which is pretty ridiculous.
This is my best support:
-Can give each other armor bonus.
-Gwendolyn with +6 Def/Res from Sheena is a great wall, even more with Renewal.
-Sheena can use Reciprocal Aid in order to take Gwen's life if necessary and it will not be a problem because of Gwen's Renewal.
-Gwen can use Swap on Sheena in order to protect her against red enemies or receive protection from green enemies.
Pivoting hector using lyn makes him a faster mover, which also makes things die faster in less turns , and with max support and spur attack 2 gives her 5 more damage per attack. Plus right this is the closest I can get to the ship in the game right now.
With Rein's native goad cavalry, lyn gets 6 points to speed and attack which can further stack my her being my personal support and hone cavalry. When all's said and done, she has 48 and 59 attack on initiation with swift sparrow and a Brave Bow+, making her one of the best offensive units out there, losing 0 matchups and winning against 165 of the 168 vanilla heroes in the game.
Should be pretty self explanatory. Kagero is broken already, and assuming you keep Lucina's special lance and Drive Speed (not sure why you would change them in the first place), you're giving Kagero a +5 ATK/ +8 SPD boost by just placing Lucina next to her. This lets her pretty much ORKO any unit that isn't extremely bulky
Now this is a bit of a tough sell considering both units are used to buff other team mates. Together however they practically push each other to pretty high limits with Eirika allowing Brave Lucina to be even more flexible with whatever set up she has with Eirika honing more attack and other stats depending on what you give her and allow Eirika to dominate on other red and green units practically guaranteeing a lot of ORKO's if Triangle Adept is being used even with just +3 to her generally low attack. The repercussion is that both support characters end up supporting themselves more than other team mates but if you can find a complimentary support group then this should work more times than not.
Any dancer paired up with Bridal Cordelia is generally a solid way to use the character and this can be even furthered with Bridal Cordelia having Escape Route active and whatever dancer you have with Wings of Mercy. This basically means Bridal Cordelia can move anywhere (near her other team mates) on the field and the dancer can still keep following her all the while Bride Cordelia for the most part barely has to move too far away from the dancer to benefit from the support boosts. This also is extremely helpful if using a Brave Bow to get Bridal Cordelia to get more quad hits in. Heck if you have a +spd Bridal Cordelia and they have the support bonus, that basically makes her reach 40 speed which coupled with a hone or spur speed can gaurentee doubles over characters that are set up to reach over that speed.
This pair is extremely effective and takes advantage of the owl effect innes's bow has. When next to lucina, innes gains +5 atk, +8 spd, +4 def and +4 res. These boosts allow innes to take care of any mages that threaten lucina while she is able to tank blue and red units and Together they can take care of greens as long as it isn't an emerald axe wielder. If innes has summoner support it is an additional +2 in every stat and 5 hp which adds to his survivability
Magvel royalty do such a great team. With Ephraim's support, Innes can get +4 to all stats if they are next to each other (Thanks to Nidhogg). If surrounded by other two allies, that's +8 to all stats. If Ephraim has his common support build, that's +11 atk/+12spd/+12def/+10res to Innes. If Innes is your summoner support, that's 2 points more to all stats and +5 to hp. Disgusting.
Basically any Blade tome user alongside Ephraim or Eirika. I feel that Katarina and Ephraim work the best since Katarina covers Ephraim's weakness to greens and Ephraim in turn defends Katarina against blues and physical reds. Nino and Eirika can be used to the same degree
Both of these units are known to be incredible nukes, and pairing them up will not only allow them to be even more busted than they already are, but they can also survive more MUs with the speed boost.
The new lyn is a beast,but she can use a partner. Thats where camus comes in. With lyn packing fortify cavalry and camus hone cavalry, they will turn into bow and shield. Not to mention the +2 to all stats. On top of that, lyn's good resistance and camus'es good defense means they can tank magical and physical attacks alike. Its recommended both of them run reposition, or camus runs swap
Given that Delthea buffs melee users anyways, bonding with Ike makes him all the more dangerous. If Delthea has her C slot skill as a spur/drive attack, that gives Ike a total of +10-12 attack. And all Ike has to do is stay still as he baits and decimates anything that dares attack him.
Futhermore, an Ike with both Fury 3 and Vantage 3 makes this bond even more frightening. Allowing Ike to further increase his OHKO potential.
This here is my first support that I did. I wanna form a team with my waifu Selena and my guy Ike. I chose Brave Ike cause I did not wanted to get in the risk of bringing 2 sword characters. These 2 are my most favorite fire emblem characters so I had to do a support of them. I gave Brave Ike a buff skill to raise a stat further when using the spur support buffs. Basically Brave Ike takes care of Selena's blue nightmares while Selena takes care of any greens Brave Ike might end up struggling. This support works well for me.
S!Corrin benefits the most from this pairing, as she is the primary attacker in 9.9/10 situations. Hinoka* serves as a meat shield boosted by Corrin's Fortify Fliers while Hinoka turns Corrin into a nuke with her coveted Hone Fliers. S!Corrin and Hinoka are usually attached at the hip anyway, so the extra stat boost is hardly difficult to initiate. Reposition on Hinoka is also highly recommended.
*Hinoka can be subbed for any flier who has inherited Hone Fliers
With Guidance 3 equipped, Tana can airlift Hector across the field, while also fighting any red units that may threaten him. Positioned correctly, he can use distant counter to bait and protect Tana from bow wielders.
Brave Lucina is an absolute beast with handing out buffs. The +6 speed from the combination of her weapon and Drive Speed 2 can work absolutely wonderfully with units who can run brave sets well, such as Legion. Legion can very easily take care of Brave Lucina's enemies, such as bulky green and blue units and most mages with a combination of the previously mentioned Brave Axe+ and Desperation in combination with the HP loss from Fury 3 already on his base set. Lucina, on the other hand, can very easily handle most of Legion's enemies, which includes almost every red unit. This combination can be very deadly if played correctly and even deadlier if a dancer is tossed into the mix.
These two childhood friends worked well together on the battlefield in Elibe, and the mini Tempest Trials are no different. With Eliwood's high res allowing him to tank more than a few non-blue magic hits and Distant Counter in Hector's arsenal, the two can take down mages left and right.
Adding on the extra edge with Brave Lucina's abilities, Leon can get an amazing 12+ speed boost with rally speed, even a neutral speed L&D Brave Bow Leon can pass 40 speed. Not to mention Lucina herself can tank herself(not mages) to keep Leon protected.
Both already have well rounded stats and Nowi with fury and swordbreaker can wipe out any threat to Julia. While Julia's breath of life can support nowi and finish off anyone Nowi won't kill. (atk ploy seal is also an awesome help on Julia with her high res)
Axe Ike (Ake? Ixe?) pairs really well with DC Zephiel. Stick them with a DC Amelia and brave lance Effie power couple, then throw in some armor buffs and a couple of swaps/repositions and you’ve got an unstoppable wave of destruction
Both are very powerful mages that can KO a wide swath of enemies. I gave both of them Renewal and Ardent Sacrifice, so they can act as healers in a sense. They can give an ally 10 HP and then regain that lost HP two turns or less later. Since they both have this combo, I often put them together anyway so they can trade off between attacking and healing, so it made sense to put them together as supports, too.
Most Offensive team.
Linde with Fury on her will kill everything, with her Draconic Aura no one can stand her especially her speed after getting support. And Olivia will support her with her WOM, and Olivia also can give cheap damage to green unit so Linde can finish them off. I change her Hone Atk with Hone Spd so Linde cannot be stopped...
Double Dragon, 2017 edition. Factoring in Ninian's Fortify Dragons, this team-up makes a Fury A!Tiki almost unscratchable. If you have a +DEF boon on your Tiki, and invest your Summoner Bond in her as well, she's able to tank a number of blue units decently with a whopping total 51 DEF (with 53 ATK as well given that setup).
This makes her a solid check to / bait for Horse Lyn as well (assuming no Brave Bow) since she can still counter. Just... keep her away from Reinhardt and other blue tomes.
Introducing the new support system, this dynamic duo can push Mae's speed to the heavens. (Marth can be replaced with Lyn)
Considering the player owns a +Speed / -Defense Mae with Fury 3, with the help of Marth/Lyn's Spur Speed, it is possible to bring her stats into an easy 35/51/45/17/35
And that's with one adjacent ally, Marth! With an Owl user as the main focus of a duo support, you can easily acquire a formidable ally that can never be doubled, as well as turning squishy glass cannon mages into a wall!
Owl tomes baby, it's time to hoot hoot in the horsehouse ayy lmao
The pair has excellent synergy, with Eirika providing the buffs needed for Nino to dominate, and Nino dealing with the blue units that Eirika struggles with. Can be substituted for any buff bot + blade tome user pairing.
Red sword glass cannon meets blue tome glass cannon. Delthea's weapon already boosts Hana's amazing power higher than ever. Now tack on 2 more ATK and SPD and she will decimate her foes. Delthea can take care of the tanky blue units that may trouble Hana as well as effectively duel other blue tome-users (even though Hana will have no problem dispatching them as well).
Hector and Lyn combine forces once more to cover and bait each other's weaknesses. Lyn will be able to tank red and green mages as well as deal with sword units while Hector can lure the blue mages and deal with axes and lance users. Great for Mini-Tempest Trials (9/7/2017).
This unlikely duo form a team of chosen heroes that allows Ike to wield his Urvan with unprecedented agility. Just as his father Greil had Titania, all Ike needed was Lucina to master his father's memento.
