List of Staff Units and Ratings

Lower Priority Units

The units not listed in this page are either in the B Tier or below. The main reason for this is that there are alternative heroes that fulfill their roles better than these units.

These units should not be promoted to 5★ unless you either have a surplus of feathers or they are one of your favorite characters in Fire Emblem.

Of course, if they are one of your favorites, you should unlock their potential and use them!

Tier List Criteria

This 4★ Unlock Potential Tier List primarily takes into consideration the full strength and skill access the unit has at 5★. In addition to that, whether or not the unit has access to a powerful special effect refine is also taken into consideration. To a lesser extent, the ease of use of the unit is taken into consideration but to a much lesser degree.

Ease of use refers to if whether or not a unit needs to meet very complex trigger conditions to be effective. It also means if whether or not a unit only shines in niche situations.

Which units should I use Unlock Potential on?

Refresher-Assist Units

In Fire Emblem Heroes, refresher-assist units are very powerful and important as it allows your most powerful units, to commit to two actions in a turn. Because they frequently become part of your line-ups as you head into harder or more competitive maps, it is wise to grant them a power boost through Unlocking their Potential.

Staff Healers

In modes such as Tempest Trials+ or Chain Challenges, healers become very important as you are sure to take small increments of damage per map. Without sustain, you are bound to fail in multi-map game modes. In general, it is recommended that you have at least one reliable 5★ healer. If you can aim for one with cavalry movement, the better!

List of Staff Units and Ratings

Units with powerful exclusive weapons

Since these kinds of weapons would not be present on any other character, a unit can be worth the feathers just because they possess a mighty weapon. For example, Reinhardt here has always been one of the most popular and go-to units in FEH because of his powerful Dire Thunder.

Fire Emblem Heroes adds new weapons and new special effect refines monthly, so who knows when your favorite characters get a mighty weapon that finally allows them to go toe-to-toe with the strongest units in the Arena!

List of Units with Exclusive Skills

Favorite characters!

Speaking of favorite characters, whether or not your favorite characters are at the top of our Tier Lists, we argue that it is always worth Unlocking their Potential. It makes playing the game so much more fun if you are playing with your favorites. You have nothing to lose as no unit is deemed unviable with enough merges, dragonflowers, and skill inheritance upgrades!

Tips & Notes for Unlock Potential

Use Unlock Potential on units that cover your main units' weaknesses

While playing the game, you are bound to develop some favorites that are reliable on any map whether it be PvE or PvP. At this point, it is only natural to deploy units that naturally complement them and cover their weaknesses. It is recommended that you Unlock their Potential because your most powerful units deserve some very powerful allies to storm battles with!

Example on a all-cavalry team

Xander [8.0/10]

Reinhardt [9.0/10]

Cecilia [8.0/10]

Nanna [8.5/10]

Consider this team whose main units are Xander and Reinhardt. They will spearhead the offense of this team, and they can do so very reliably, but they are not without weaknesses.

Cecilia, is a good choice for a 3rd option as she specializes in taking out Blue units with her Tome of Order. This way, the team covers all sides of the attribute triangle.

Nanna, is simply the healer of the team. Because she too is a cavalry unit, she can carry Sacred Seals or skills like Hone Cavalry that compliment the team.

Strongly consider the free units from Tempest Trials+ and Grand Hero Battles!

Just because they are free, does not mean that they lack in firepower! Some are meh, but some are actual powerhouses that do their job properly with minimal investment! Make sure to participate in Grand Hero Battles and take part in Tempest Trials+ to get free heroes. If they do not find spots in your teams, they can be used as fodder!

To get previously released free units, or if you plan on getting merges, you can use Heroic Grails to claim copies of these free units.

Use Unlock Potential on the Askr Trio

Alfonse [7.5/10]

Sharena [7.5/10]

Anna [7.5/10]

The Askr trio are featured in Aether Raids and the Arena as rotating bonus units. This means you can use them for you to be able to score more in these game modes. They are also featured in many quests that you can complete to get valuable resources such as Orbs.

These use cases jusitfy the small fee of 20,000 Hero Feathers per Askr member as the investment will definitely help you in the long run. The sooner you Unlock their Potential, the sooner they show you their true value.

Try not to simultaneously invest on similar units

Make sure that you are investing in a wide range of units. For example, avoid investing in Nagi if you already have a well-invested Winter Sothis and vise-versa as they are both tanky green dragon units that do well against magical attacks and dish out heavy damage in both phases.

Only do so if you are running out of options in modes such as Arena Assault.

How to strengthen your units on top of Unlock Potential

Skill Inheritance Equipping Sacred Seals Merging Weapon Refinery Summoner Support Ally Support Dragonflowers

Turning a unit into a 5★, is not the limit of a unit's growth. You can power-up units even further through other means. Check out the articles above to know how to power-up your units even further!

4★ Unlock Potential Tier List Summary

This Tier List is based on our recommendations for using Unlock Potential on 4★ Heroes. 4★+10 Heroes have the same stats as 5★+5 Heroes, so it is sometimes better to continue to Merge Allies with a 4★ Hero instead of using Unlock Potential to increase their rarity. For this reason, you should prioritize Heroes who gain powerful Exclusive Skills at 5★ or Heroes that you simply love when using Unlock Potential.
