"Sengoku Asuka Zero": Fealty Guide
Cassidy is an author and a scientist who enjoys playing mobile games in his free time.
Sengoku Asuka ZERO is a mobile role-playing, gacha game set in the Sengoku period of Japan, in which you recruit, train, and promote samurai women to battle against enemy teams and advance through a story about good, evil, and friendship. An important, but rather complex, aspect of this game is fealty.
What is fealty?
Fealty is essentially a measure of how much you have interacted with your warriors in the castle town. It allows your warriors to power up their EX attack, grants you the chance to forge new weapons, and lets you build and level up the buildings in your castle town to enhance your warriors and gain coins. As your fealty increases, your castle town's population will also grow, prompting increases in buildings that grant coins or increase your supply limit.

On a warrior's fealty screen, you can see what building and weapon they will suggest when their fealty reaches the appropriate level.

How do you increase a warrior's fealty?
1. Click on a warrior whenever a heart pops up in your castle town. After your town's population increases enough, you will be able to swipe instead of clicking on hearts and coins, which saves time.
2. Use gems to increase a warrior's fealty by 3, 10, or 30. This is done on the warrior's profile screen by clicking the Items button. Gems can be acquired through missions or in the exchanges.
How high can fealty get?
A warrior's max fealty is determined by her promotion level. You can increase max fealty even more through ascension, though only a few characters are eligible.
Promotion Level | Max Fealty |
---|---|
No promotion | 50 |
1st promotion | 200 |
2nd promotion | 350 |
3rd promotion | 500 |
1st ascension | 600 |
2nd ascension | 750 |
3rd ascension | 850 |
4th ascension | 999 |

When a light bulb appears over a warrior's head, click on her to receive a building or weapon suggestion or to upgrade her EX attack.

What happens when fealty increases?
Once a warrior's fealty reaches a certain level, you will see a light bulb appear over her head. By clicking on it, you will receive a building upgrade, a weapon design, or an EX attack upgrade. A weapon design can be received at any fealty level where you might receive a building upgrade. If you receive a weapon design, you will not receive a building upgrade that time. Fealty level rewards are shown in the following table.
Fealty | Reward |
---|---|
5 | Building construction/upgrade |
15 | Building upgrade |
30 | Building upgrade |
60 | Building upgrade |
100 | EX II |
120 | Building upgrade |
180 | Building upgrade |
240 | Building upgrade |
300 | EX III |
320 | Building upgrade |
400 | Building upgrade |
480 | Building upgrade |
500 | EX IV |
