Unlocking Potential is one of the many ways where you can power-up your favorite units in FEH! Because this process costs quite a lot of resources, you might be wondering when it is the best time to use this feature. To know more about Unlock Potential, please read on!
List of Contents
Unlock Potential raises a characters' number of stars. This gives better stats and access to more powerful skills. Access to these skills opens them both up for combat usage or for fodder.
Take note that upon unlocking a unit's potential, their level is reset to 1 regardless of how much EXP they have. You can take advantage of this feature to get lots of EXP! It is discussed in the next section of this article.
You will need Hero Feathers to unlock a unit's potential. Below is a table that lists the number of feathers required according to a unit's rarity.
|1 ⇨ 2||20|
|2 ⇨ 3||200|
|3 ⇨ 4||2,000|
|4 ⇨ 5||20,000|
Since SP is kept upon Unlock Potential, you can take advantage of the SP gain in lower rarities, then use your Hero Feathers, then have SP gained through training through levels again. However, it will be tedious to train 1★ to 3★ units. So, you may want to unlock their potential when they hit Lv. 20.
A skill does not need to be learned in order for you to be able to fodder it off. This means that you can unlock a unit's potential off the bat if you just intend to get a skill at a certain rarity.
Above are some units available at 4★ and 3★ rarities that get a huge powerboost upong reaching 5★. All but Klein in this sample size are obtainable from using Heroic Grails. This means that you can obtain your own 5★ +10 unit in time if you focus enough resources on getting one.
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.
See the 4 Star Hero Unlock Potential Tier List to know more about the heroes most worthy of promotion.
IVs do not change upon unlocking potential. Both banes and boons will be kept. Make sure you know the IVs of the unit you are upgrading before promoting them to a higher rarity!
Since 5★ +10 units are very expensive, it may be best to aim for 4★ +10 units depending on the situation. Of course a 5★ +10 is more powerful and 4★ units will never get access to some weapons, but for something like Arena Assault, Squad Assault or Rival Domains, you may want to opt for a large number of cheap but effective 4★+10s.
Stat-wise 4★ +10 merges are stronger than 5★ units without merges. In fact, they are equivalent to 5★ +5 units, but are extremely cheaper. Take all these factors into consideration before deciding on which type of unit to go for!
