What is Power Up?
Uses Extra Heroes and Pets to Enhance
Power Up is a feature that allows you to enhance a hero's or pet's Attack, Defense, and HP by consuming other heroes or pets as materials. This feature becomes available after clearing Adventure 1-6. There are two types of Power Up: Power Up Heroes and Grow Pets. Once a unit is powered up, a plus (+) value will appear on its icon to indicate the stat boost.
How to Power Up
1. Select Power Up Heroes or Grow Pets
Tap Power Up at the bottom left of the home screen. Select Power Up Heroes to upgrade characters, or Grow Pets to enhance pets.
2. Switch to Enhance Tab for Grow Pets
When selecting Grow Pets, the screen will default to the Hatch tab. To proceed with enhancement, switch to the Enhance tab on the left. For Hero Enhancement, the Power Up tab is already selected by default, so you can go straight to Step 3.
3. Select Character or Pet to Power Up
After selecting the base hero or pet you want to power up from the options at the bottom of the screen, choose the required materials and proceed with the power-up. Take note that only 4-star and higher pets can be powered up. Pets 3-star and lower will not appear in the base selection screen.
Power Ups Can Fail
Power Up has a success rate, and if the material’s rank is lower than the base’s, the power-up may fail. Even if the attempt fails, the enhancement material will still be consumed, so it's recommended to avoid using materials with a very low success rate.
 Tip! | Each time Power Up fails, the chance of success increases by 1%. |

Success Rates Are Not Combined
You can select multiple heroes as materials, but their success rates are not combined. Each one is calculated individually. If the enhancement level reaches the maximum of +5 before all materials are used, the remaining materials and any Gold spent on enhancement will be returned.
Use the Auto Add Feature
Open the material selection settings by clicking the round icon next to Auto Add. When you press the Auto Add button, you’ll register all materials that meet your set conditions instantly. This super convenient feature can save you a lot of time, so don’t forget to use it!
Power Up Uses
Increase Stats
When you power up, your Attack, Defense, and HP stats will increase, making your heroes and pets stronger in battle. This enhancement method is just as important as leveling up and is essential for clearing high-difficulty quests.
Enables Rank Up and Fusion
To use other enhancement methods like Rank Up and Fusion, you must first raise the enhancement level to the maximum of +5. Rank Up is especially important and a key way to strengthen your heroes and pets.
 Tip! | Even after ranking up, the hero level remains the same, but the enhancement level returns to 0. To rank up again, you need to raise the enhancement level to +5 once more. |

Power Up Success Rate
Base and Material Rank Success Rates
| 6★ Mats | 5★ Mats | 4★ Mats | 3★ Mats | 2★ Mats | 1★ Mats | |
| 6-Star | 100% | 50% | 25% | 10% | 1% | 0.1% |
| 5-Star | 100% | 50% | 25% | 10% | 1% | |
| 4-Star | 100% | 50% | 25% | 10% | ||
| 3-Star | 100% | 50% | 25% | |||
| 2-Star | 100% | 50% | ||||
| 1-Star | 100% | |||||
The success rate of a Power Up is determined by the difference between the base's rank and the material's rank, as shown above. If the material's rank is the same as or higher than the base's, it will succeed 100% of the time, and the success rate decreases as the material's rank gets lower.
Recommended Use for Each Material
| Material Rank | Recommended Use |
| 1-Star Material | 1-Star to 4-Star |
| 2-Star Material | 2-Star to 5-Star |
| 3-Star Material | 3-Star to 6-Star |
Since a success rate of 1% or 0.1% is too low, a good rule of thumb is to use materials that give at least a 10% success rate, preferably 25% or more. Also, it is more recommended to use 4-star and above materials for Transcendence rather than as enhancement materials.
