What is Rank Up?
Rank Up is a progression system that lets you increase the Rank of a Hero or Pet once they've been Enhanced to +5. It unlocks after clearing Adventure 1-20 and has two types: Hero Rank Up and Pet Rank Up, each with its own method.
Maximum Hero Level is 30
The level cap for heroes is currently set at level 30. Reaching this level cap is relatively straightforward, especially in the early stages of the game. You can level up heroes quickly by progressing through Adventure or by engaging in Ruby Farming, which provides experience and valuable resources.
How to Rank Up Heroes
Hero Rank Up Requirements
- Hero Level 30
- Hero Enhancement +5
- Required Rank Up Materials & Gold
To Rank Up a Hero, you must meet the three requirements listed above.
1. Reach Level 30

To Rank Up a Hero, they must reach Level 30. Start by farming in Adventure Stages to level them up. The character level cap is 30, and there is currently no way to raise it .
2. Reach Hero Enhancement +5

To Rank Up, you also need Particles, which serve as Rank Up Materials. There are five types, and the type required depends on the Hero's class. The Rank and amount of Particles needed also increase with the Hero's Rank.

![]() | Since Fusing low-grade heroes has a chance to become Rare or even Legendary Heroes, try fusing fully Powered Up uncommon heroes to see if you get 5 or 6 stars of the heroes you're looking to upgrade. This method can partially skip steps needed for the Ranking Up Rare or Legendary Heroes and might save Rank Up Materials. |

How to Rank Up Pets
Pet Rank Up Requirements
- Two of the Same Pet at +5
- Required Amount of Gold
The Pet Rank Up requirements are listed above. Unlike Heroes, Pets don't have levels, so they require a duplicate as Rank Up Material instead of Particles.
1. Enhance to +5 via Grow Pets

To Rank Up a Pet, it must reach Enhance Level +5. Use unwanted Pets as Material to raise the enhancement level to +5.
2. Rank Up with Enhanced +5 Duplicates
Enhance the same Pet you want to Rank Up to +5. The Pet's Rank must also match, so to Rank Up a 4★ Pet to 6★, you'll need a total of four of the same Pet.
![]() | Pets can be obtained through Egg Hatching, Fusion, Crafting, or Summoning. |

3. Rank Up in Grow Pets → Rank Up Tab

Benefits of Rank Up
Increases Rank and Stats

Rank Up increases a Hero and Pet's Rank and boosts its stats. Like leveling up, it's an important training method and essential for clearing high-difficulty quests.
Max Rank List by Hero Type
Type | Max Rank |
Legendary / Rare | 6-Star |
Uncommon | 4-Star or 5-Star |
Common | 3-Star |
Enables Enhance Again

Even after a Rank Up, a Hero's level remains the same, but their Enhance level resets to 0, letting you Enhance to +5 again for additional stat boosts. Afterward, Rare and Legendary Heroes can be Rank Up further to 6-Star.
Skill & Ultimate Enhancements for 6★ Heroes
Once a Hero reaches 6★, you can perform Enhance Skills and Ultimate Enhancement. The materials for these enhancements are harder to obtain, making them more challenging than Enhance or Rank Up.

How to Get Rank Up Material Particles
1. Collect from Power Up Dungeons

Clearing a Power Up Dungeon rewards you with Particles. There are five dungeon types: Fire, Water, Earth, Light, and Dark, so challenge the dungeon that provides the Particles your Hero needs to Rank Up.
![]() | Countering status ailments is crucial for clearing Power Up Dungeons. In the early game, focus on dungeons your current roster can handle to increase your number of Ranked Up Heroes. Crafting key Heroes is also recommended. |

2. Use Rank Up Material Boxes

You can also obtain Rank Up Materials using a Rank Up Material Selection Box from Home → Inventory → Consumables. Rank Up Material Selection Boxes can be obtained from Login Bonuses, Expedition Event, the Shop, and more.
3. Perform Material Exchange

Exchange Type | Details |
Fusion | 5x Low-Rank Materials → 1x Material of Next Rank |
Dismantle | 1x High-Rank Material → 3x Materials of the Previous Rank |
In the 'Material Exchange' section at the center of the Rank Up screen, you can use Fusion to upgrade low-rank Materials to the next Rank, or Dismantle high-rank Materials into the previous Rank. Fusion is useful when it's difficult to clear high-level Power Up Dungeons.
4. Purchase from the Shop

Rank Up Materials occasionally appear in the General Store. If you have extra Gold or Rubies, buying them there is a convenient option.
