"Unlock Potential", as well known as "Awakening" in the other smartphone games, is a way to increase the character's rarity by one star with spending awakening materials. Even a character of 1 star can be awakened to a powerful 5 star character by awakening multiple times.
Stats increase with "Awakening"
Character’s stats are all very close at level 1, regardless of rarity (number of stars). As the rarity rises, the base stats will improve, so as you go through the game you want to get each character up to 5 stars.
Characters learn new skills
Unless you awaken and raise your character's rarity, the hero has limited skills to learn. There are some skills that it can not learn unless the rarity of it is a 4 or 5 star. Awakening is also very important in order to maximize the character's strength, as the max stats are much higher each time you awaken.
Level returns to 1
When you awaken a character, their level goes back down to level 1, and their stats temporarily decrease. You must then train the unit and give them XP in order to raise their stats again. The timing is very important as a level 1 5 star character won’t be as strong as a level 40 4 star character. However, awakening is still very much worth it because 5 star characters have the highest max stats available as well as the best skills.
SP remains
A character who awakens raises the rarity by 1 star, although the status itself returns to level 1, it maintains it’s SP . SP (skill point) is necessary to master skills. You can decide how to spend your SP, but remember that only certain skills are available at each rarity level.
3 star → 4 star is particularly remarkable
If you awaken a hero from 3 star to 4 star and level up to at least level 20, then you will earn at least 200 SP. The skill that you can get a hero to learn when reaching 4 star is often about 50 SP, so you get the skill points for that.
How to awaken
Where to awaken/merge
Go to "Allies" menu, and then tap "Advanced Growth".
Reach Level 20
For any star rarity, if you reach Level 20 or higher, you will be able to awaken your character. First of all it is necessary to raise the unit to at least level 20.
Required awakening materials
The awakening materials, badge and the hero’s feathers, are always needed. The feathers can be extremely difficult to obtain, as we really can only obtain them through the arena and a very small amount each day from friends.. The badges are mainly acquired through the training sanctums. The Great Badges are available at sanctum 6 and higher.

When to awaken
Level 20 or so is recommended timing!
In relation to consumption of stamina, training at level 25 or later is a little tough. The best timing of awakening is around level 25 as it costs much more stamina to gain each level once you reach level 25. Again, the one exception to this is if you plan on using the character a lot before awakening them.
There is no difference in status even if you raise the level and awake
Even if you awaken a character of level 20 and a character of level 40 , there is no difference in their stats . Although the above-mentioned skill points increase, the status of the unit returns to level 1 when awakening, so even if you continues to raise the level, it won’t have any effect once you’ve awakened the character. Many people will still raise their characters past level 20, but that’s usually only if you are planning on using that character a lot before awakening them.
Merging characters
By merging the characters, you break the level limit and earn SP. However, the character consumed will be lost. Also, if ★ rarity on the consumption side is equal or higher than the other unit, the stats value will rise. By breaking through the limits, you also don’t need as many hero’s feathers or badges in order to awaken the character.

Tips
The merging bonus is reset when a unit is awakened
The bonus (+ attached to the back of the level) given when breaking through the limit is reset when the character is awakened . You should really only merge characters when you have reached 5 star as you won’t be awakening that character anymore.
