** Surge Sparrow (exclusive to Melee units), Remote Sparrow (exclusive to Ranged units) and Flash Sparrow (exclusive to Infantry and Armor units), are direct upgrades to Swift Sparrow 3, where not only all three give +7 Atk/Spd during combat if the user initiates combat, as opposed to +6 Atk and +7 Spd with Swift Sparrow 3, but it also allows the user to recover HP equal to X% of the user's maximum HP when the user triggers a damage special during combat, where X = 20 x the maximum special cooldown the user has equipped, + 10, up to 100% for Surge Sparrow, reduces damage taken from the foe's first attack by 30% for Remote Sparrow, and +1 special buildup per attack performed if the user has no less than 5 Spd lower than the foe during combat for Flash Sparrow.

** Surge Sparrow, exclusive to Melee units, and Remote Sparrow, exclusive to Ranged units, are direct upgrades to Swift Sparrow 3, where not only both give +7 Atk/Spd during combat if the user initiates combat, as opposed to +6 Atk and +7 Spd with Swift Sparrow 3, but it also allows the user to recover HP equal to X% of the user's maximum HP when the user triggers a damage special during combat, where X = 20 x the maximum special cooldown the user has equipped, + 10, up to 100% for the former, and reduces damage taken from the foe's first attack by 30% for the latter.

** Since the DarkerAndEdgier Book II, there has been a banner featuring Fallen Heroes (which usually comes with a Grand Hero Battle as well). These heroes are supposedly based off possessed or cursed versions from the games they come from. They usually feature at least one new unit and the rest of them are alts. For Book II, there's Hardin, Male Robin (as Grima), Celica and Takumi. In Book III, there's Mareeta (who got a normal version of herself later), Berkut, Corrin (Female), Tiki (Young) and Delthea. For Book IV, we have Ike, Corrin (Male), Lyon, Julia, and Ashnard. For Book V there's Morgan (Male and Female), Dimitri, Edelgard, and Orson. For Book VI we have Lilith, Ninian, Gustav, Rhea, and Muarim.

** Many characters that had previously been unplayable antagonists and supporting characters in their home games can be recruited in ''Heroes'' as playable units. [[labelnote:These characters are:]] [[VideoGame/FireEmblemShadowDragonAndTheBladeOfLight Naga, Medeus]], [[VideoGame/FireEmblemGaiden Duma, Rudolf, Mila, the Brigand Boss, Berkut, Rinea]], [[VideoGame/FireEmblemGenealogyOfTheHolyWar Annand, Díthorba, Ullr, Hilda]], [[VideoGame/FireEmblemThracia776 Reinhardt, Kempf, Veld, August]], [[VideoGame/FireEmblemTheBindingBlade Idunn, Elimine]], [[VideoGame/FireEmblemTheBlazingBlade Leila, Bramimond, Sonia, Limstella, Mark]], [[VideoGame/FireEmblemTheSacredStones Fomortiis, Vigarde]], [[VideoGame/FireEmblemPathOfRadiance Greil]], [[VideoGame/FireEmblemRadiantDawn Yune, Altina, Jorge, Ludveck, Dheginsea, Ashera]], [[VideoGame/FireEmblemAwakening Mustafa, Phila, Cervantes]], [[VideoGame/FireEmblemFates Iago, Garon, Mikoto, Lilith, Arete, Hans, Anankos]], [[VideoGame/FireEmblemThreeHouses Sothis, Kronya, the Death Knight, Rhea/Seiros, Nemesis, Solon, the Gatekeeper, "Cornelia"/Cleobulus]] [[VideoGame/FireEmblemEngage and Lumera.]][[/labelnote]]

** New Year's banners feature every type of unit except armoured units, and starting from the second NY banner and onward, they have featured units who are original to ''Heroes'' itself.

* OneStatToRuleThemAll: Generally speaking, you're doomed if the other guy has more Speed than you. Speed-based damage reduction is so prevalent that your theoretical FragilSpeedster units can end up way tougher to actually kill than your MightyGlacier units.

** Summer banners feature any kind of unit [[note]]For five years, they featured every unit type ''except'' armoured units, until Harmonized Summer Edelgard and Altina broke that streak in the first Summer banner of 2022[[/note]], and they pop up twice a year, with the second always following the first.
** Dancer banners feature [[ExactlyWhatItSaysOnTheTin dancers]], with every unit that's featured having [[ExtraTurn refreshing]] abilities. They usually follow up the summer banners, although 2021 did not feature them.
** Halloween banners feature at least one armoured unit.
** Winter banners usually feature at least two armoured units.

*** There are 7 variants for Eirika[[note]]Regular, Sacred Memories, Legendary, Winter, Young Duo (with Ephraim), Brave, Summer[[/note]].

** The reason why you fight all the Heroes in the story. Heroes defeated by the Emblian Empire must agree to the contract, which states that they must serve the empire, or they'll presumably be killed. However, the contract is null and void if someone else defeats them in combat. A majority of Book I (and a few Paralogues) focuses on freeing the Heroes from the Empire's contracts. From Book II onwards, the plot is less focused on the contracts, although some Heroes (i.e. Regular Micaiah, Sacred Memories Eirika, Exalted Chrom, Kaze) still comment on them.

** Downplayed with the characters drawn by Yamada Akihiro (Jagen, Ogma, Regular Zephiel, Gunter, Bantu, and Mila), Rebecca (drawn by Hoshino Lily), Regular Idunn (drawn by Yamada Kotaro), Legendary Seliph (drawn by Akira Egawa), Guinivere (drawn by Asatani Tomoyo), Legendary Sigurd (drawn by Rika Suzuki), and Nifl (drawn by Suzuhito Yasuda). While most characters' special attack portraits are edited versions of their normal attack portraits, these characters possess unique artwork for their special attacks.

** Certain effects on weapons and skills cannot stack with other identical effects to prevent certain builds from being overpowered, such as Heavy/Flashing Blade unable to stack with other +1 special buildup skills such as Bold Fighter to get +3 special buildup per user's attack, Guard weapons unable to stack with other -1 special buildup skills such as Guard and Crafty Fighter to inflict -2 special buildup on the foe per attack, and the double attack from Brave, In The Moment and Ninja Training weapons unable to stack with Brave Celica's Double Lion and the [Triangle Attack] status to get a quad attack from one round of combat.

** Due to how Staff units are mechaically unusual, there is bound to be some clauses whenever something that was once barred from them are introduced to them in updates and banners:

** Still Water grant its user up to +5 Atk/Res for the 3rd tier and +7 Atk/Res on the 4th tier, but also inflicts -5 Def with the 3rd and 4th tier versions. Solid Ground has a similar effect, except the Def and Res are switched from Still Water. Alfred's Self-Improver is a stronger version of Solid Ground, where it grants the usern +10 Atk, +5 Spd and +20 Def, and inflicts -1 special buildup per attack during combat if the user is at 25% HP or above at the start of combat, at the cost of -5 Res.

** The -owl tomes, Regular Innes' Nidhogg, Katarina's Reese's Tome, and the unique refine for Regular Soren's Wind's Brand, Raigh's Hermit's Tome, gives +2 Atk/Spd/Def/Res during combat for each ally adjacent to them.

* RotatingArcs: During the relative lull in the Book updates in July since 2021 for the Summer seasonal banners, the Books 3 installments earlier gain focus again with the release of the corresponding Tempest Trials+ Series and videos on the official Nintendo Channel.

** Older Legendary and Mythic Heroes also receive next tiers to their SecretArt through Legendary & Mythic Hero Remixes with version updates. For example, Legendary Lucina's Future Vision, which acts like Swap with the addition of granting her an ExtraTurn after movement, has Future Vision II, which functions the same as Future Vision with the addition of inflicting -7 Atk/Def to the nearest foes of her and her target ally after movement, and Regular Eir's Sparkling Boost, which recovers 10 to the most damaged ally at the start of her turn, has Sparkling Boost+, which recovers 20 HP instead and gives allies who are at 50% HP or above at the start of combat +5 Res during combat.

** Averted with the dancers when they use the Dance/Sing/Play command, and any healer with the Rescue(+), Return(+) and Nudge(+) support command, even though they can get EXP when doing that in the main games.

** Characters drawn by Soeda Ippei (Arden, Dorcas, Walhart, Garon, Travant, and Darros) are rendered in a considerably more realistic style than the norm.

** The Lull Skills allow the user to ignore any field stat boosts on enemies during combat, but only to two stats. However, it also inflicts a -3 stat debuff on those two stats on the foe during combat. They also work against any weapon type unlike with the Dull skills, but they're also only available on Infantry and Cavalry units. Altena's Earthly Gáe Bolg also has this effect, except it inflicts -5 Atk/Def instead and excludes both effects on flying foes. The Pirate's Pride and Unbound weapons and Blackfire Breath+ also has this effect, except it inflicts -5 to two of the foe's stats instead and only activates if the user is not adjacent to an ally. Seteth's Spear of Assal has a similar effect, with the user gaining +4 Atk/Spd during combat, as well as ignoring any field stat buffs to the foe's Atk and Spd during combat, if the user is within 2 spaces of an ally.

** Erosion Captain Skill from update 6.5.0 onwards now allows the Captain to negate [Savior] from activating on foes before the start of combat.

** Lucia's Queensblade takes this to the extreme, as she negates on her and foes that triggers Special that trigger before or during combat (excluding Røkkr AOE specials), defensive terrain effects, support effects, guarantee and prevents follow-up attacks, prevents counterattacks, change attack priorities and other allies or foe's skills during combat.

** Brave, Gem, Firesweep, -raven, and -blade weapons, as well as the Poison Dagger+ and Kitty Paddle+, were popular for players to inherit onto heroes to exploit their niche in the MetaGame early in the game's life. Upon the release of version 2.0.0 in December 2017, those weapons were the only ones which did not receive any refinements, even though unique weapons with the same effects as those skills released later on in updates, such as Regular Titania's Draconic Axe having the same effect as Emerald Axe+ and Roderick's Steady Lance having the same effect as Firesweep Lance+, did get refinements later on. The In The Moment[[note]]Ninja Katana, Ninja Yari and Ninja Masakari[[/note]] and Ninja Training[[note]]Ninja Yumi, Ninja Naginata and Shuriken Cleaver[[/note]] weapons, which are tweaked versions of the Brave weapons released in November 2020 and 2021, respectively, received the same treatment due to fears of having them be refined to be just stronger versions of the Brave weapons.

** The staff assist skills Rescue, Return and Nudge have the same effect as Draw Back, Reposition and Shove, respectively, with the addition of healing the target ally, but with the downside of using these skills does not give Exp, SP and Special charges when used, as a way to prevent Staff units to use these skills to build up Special charges, even if the target is already at maximum HP, unlike the other movement assist skills they share the same effect, where those Staff assist skills would PowerCreep those skills if it did otherwise.
** Related to that, the Offensive Staff specials have a clause that make them not build up charges if the user uses an Assist skill to prevent Staff units from building up their specials outside of combat like the other Offensive specials.
** Also related to that is that Staff weapons that gives -1 maximum special cooldown have a clause that prevent reducing the maximum special cooldown of Specials from going below 1 to prevent Staff specials that have 1 maximum special cooldown such as Imbue or Windfire Balm+ from triggering instantly from using Staff Assist skills.

** Some of the skills released at launch that are inheritable to everyone were later powercrept by later released skills usually exclusive to certain units. For example, Quick Riposte, which allows the user to have a guaranteed follow-up up attack if the foe initiates combat the user is at 70% or above at the start of combat, was later powercrept by skills such as Slick Fighter, exclusive to Armor units, which allows the user to have a guaranteed follow-up attack and negates any penalties the user has at the start of combat if the foe initiates combat and the user is at 25% HP or above at the start of combat, and Dragon's Ire, exclusive to Dragon units, which allows the user to ignore any skills that deny any of the user's follow-up attack and have a guaranteed follow-up attack if the foe initiates combat and the user is at 50% or above at the start of combat.

** Repel and Close Call, although exclusive to Infantry Sword, Lance or Axe units, are direct upgrades over Knock Back and Hit and Run, respectively, as they have those effect alongside DamageReduction if the user is faster than their foe during combat.

** The AR-O A Skills gives the unit if they're on the attacking raid team in Aether Raids stat boosts to 2 of their stats during combat, depending on how many defense structures are remaining on the enemy team, with 2 or less giving a substantial '''+10''', 3 giving +7, 4 giving +4, and 5 or more just +1, so players are encouraged to destroy enemy structures to gain the maximum benefits of these skills.

* RotatingArcs: During the relative lull in Book V updates in July 2021 for the Summer seasonal banners, Book II, which ended more than two years ago prior, has the characters of Nifl and Múspell gain focus again with the release of the Ice & Flame Tempest Trials+ Series and videos of the official Nintendo Channel.
