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.
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.
2. Reach Hero Enhancement +5
To Rank Up, a Hero must also reach Enhancement Level +5. Use unwanted Heroes as Material to increase their Enhancement Level to +5.
3. Collect Rank Up Materials
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.

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.
 Tips! | 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.
| Tips! | 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.
