Across the Fire Emblem series, players have been able to utilize countless characters in their respective armies. While many of the most memorable of these units may wield potent combative power, there are many units across the series that provide a player with additional utility outside of simply dealing damage. Whether these characters are healers or dancers, they provide much-needed assistance to one's army.
As much fun as it is to utilize powerful Paladins and Wyvern Riders, these units can't be helpful if there aren't support units to help keep them alive.
10 Genny - Shadows of Valentia
The primary healer for much of the Celica route of Fire Emblem Echoes: Shadows of Valentia, Genny is everything a player would want out of their healer and more. A priest with an excellent supportive spell list, at level one, Genny already knows both heal and recover.
Genny notably learns Invoke at level four, allowing her to summon numerous generic soldiers. These soldiers are incredibly useful, and can be used to choke points and protect a player's units. As if this weren't enough, Genny also learns physic to heal allies from afar, as well as expel to immediately remove troublesome monsters.
9 Priscilla - The Blazing Blade
Priscilla is often considered to be one of the strongest options for a player's healer in Fire Emblem: The Blazing Blade. A level three Troubadour recruited early into Eliwood and Hector's stories, Priscilla's high mobility allows her to easily maneuver maps and be exactly where she needs to be, while her mount allows her to rescue allies in a pinch. Additionally, Priscilla joins a player with a C rank in staves, allowing her to utilize many notable staves from the word go, and being a prime candidate for staff training for late-game use of high-ranking staves.
8 Annette - Three Houses
While the Blue Lions student Annette is most often associated with offensive magic due to her high magic stat and a sizable list of wind spells, she possesses unique and useful support capabilities. Rather than through healing, Annette's support comes through her excellent Rally abilities that allow her to boost the stats of allies.
While most units with Rally in three houses only have access to a single variation of Rally, by training Annette in Authority, she is capable of learning Rally strength, resistance, speed, and even the coveted Rally move.
7 Silque - Shadows of Valentia
The premier healer of Alm's route of Shadows of Valentia, Silque brings notable utility to the table that many other healers could only dream of. This is due to the fact that she learns to incredible Warp spell at the low level of seven. This means that in addition to being able to keep allies alive, Silque is also capable of helping drop powerful units behind enemy lines, often even allowing players to circumvent entire portions of troublesome maps!
6 Linhardt - Three Houses
The Black Eagles student, Linhardt shares many similarities to the previous entry of our list due to his ability to utilize the potent Warp spell. However, Linhardt has two notable distinctions. Firstly, his ability to learn physic allows him to reliably heal allies from a safe distance. Secondly, as a Three Houses character, Linhardt intrinsically has more flexibility, as players are able to train and utilize him an a myriad of ways, while Silque on the other hand is much more linear.
5 Lena - Fire Emblem: Shadow Dragon
Lena is by and large the best support unit in Fire Emblem: Shadow Dragon. The only unit capable of wielding the Hammerne staff, Lena is capable of repairing damaged weapons to provide additional uses to excellent weapons such as forged ballistae. Additionally, Lena joins a player's army with a C rank in staves and the incredible warp staff already in her inventory. While Warp is useful in each game it appears in, the Shadow Dragon version of Warp is notably potent, as it can move an ally to any tile on the map.
4 Safy - Thracia 776
Easily one of the most integral support units in Fire Emblem: 776, Safy joins a players army quite early into the game and immediately establishes herself as a mainstay of one's army. This is due in part to her high staff rank that allows her to reliably use integral staves like Warp and Repair.
3 Any Dancer - Three Houses
Dancer's are some of the most useful support units in the Fire Emblem series, allowing units to gain an additional action, effectively doubling their contributions for a turn. However, Dancers traditionally are simultaneously frail and incapable of engaging in combat.
The Dancer class in Three Houses on the other hand can be bestowed upon any student of a player's choice, and is both able to use their weapons as well as their spells.
2 Rafiel - Radiant Dawn
In Fire Emblem: Path of Radiance and its sequel, Radiant Dawn, Heron Laguz replaced dancers as the units capable of reinvigorating a player's units. While the three herons in Radiant Dawn each possessed a unique trait to distinguish themselves, Rafiel is notably quite excellent. This is due to the fact that Rafiel is capable of reinvigorating each ally adjacent to him, rather than just one at a time, multiplying his potential value each turn by four.
1 The "Stride" or "Dance Of The Goddess" Gambits- Three Houses
While this may appear as kind of a cop-out as it is not a specific character, rather, abilities produced by battalions, Three Houses's introduction of gambits is a major game-changer for the series, and brought about the most ideal support options the franchise has ever seen.
"Stride" and "Dance of the Goddess" are respectively two of the most useful tools at a player's disposal in Three Houses, providing additional movement to numerous units and reinvigorating numerous allies respectively. A trait that is truly unparalleled with these gambits is that due to the nature of battalions, they can hypothetically be equipped to any unit in the game, providing further flexibility.
