What are Pets?
Increase Stats by Adding to Party
When you add a pet to your party, you can increase the stats of the heroes in the party. Just like heroes, there are Legendary, Rare, Uncommon, and Common pets, and the rarer the pet, the better skills it has.
 Tips! | The pet content is unlocked by clearing Adventure 3-5. |
|---|
Adventure (Normal) Area 22 and Above
After the 12/23 Maintenance, Normal Adventure 22 and above Rewards will be updated. The Pet Egg (Quality, Superb, and Legendary) can be obtained as a reward.
How to Train Pets
1. Power Up to +5 Enhancement Level
First, raise the enhancement level to +5. Pets don't have levels like hero levels, so you don't need to level them up by repeatedly clearing quests like you do with heroes.
2. Obtain the Same Pet
Use methods like Hatch, Fusion, Crafting, or Summon to obtain the same pet you want to train. For pets, the same pet as the base is used as the Rank Up material.
3. Enhance the Pet from Step 2 as Well
Also, raise the enhancement level of the pet for Rank Up material from step 2 to +5. It is recommended to obtain pets for enhancement material through Hatch or Summon.
4. Rank Up the Pet
Go to Grow Pets > Rank Up, select the base and material, and spend Gold to Rank Up the pet. The material pet will only appear on the material selection screen if you have a pet that can be used as Rank Up material.
How to Rank Up & Get Materials
5. Repeat Steps 1-4 to Reach 6-Star
Repeat steps 1-4 to Rank Up to 6-star, and also raise the enhancement level to +5. Note that the base and Rank Up material must be the same pet and the same rank, so to Rank Up a 5-star pet, you need the same 5-star pet.
| Tips! | To Rank Up a 4-star pet to 6-star, you will need a total of 4 of the same pet. |
|---|
6. Release Unused 4-Star or Higher Pets
Release unnecessary 4-star or higher pets that you don't plan to train to get Star Fragments and Star Crystals. When you Release a Rare pet, you get Star Fragments, and when you Release a Legendary pet, you get Star Crystals.
| Tips! | Star Fragments and Star Crystals can be used to raise a Legendary Pet’s Bond and unlock Potentials. These upgrades at 6★ provide a much greater impact than the short-term stat gains from enhancement. |
|---|
7. Increase Bond
Give Star Fragments or Star Crystals as gifts to a 6-star pet to increase its Bond. Once it reaches a certain level, the Bond level will increase, unlocking Cheer Animation and Potential Slots. The maximum Bond Level varies depending on the pet's rarity. Rare Pets can reach a maximum Bond Level of 3, while Legendary Pets can reach up to 4.
| Tips! | Cheer Animation are pet animations you can see during battle. You can see various motions that correspond to the hero's attacks. |
|---|
8. Grant Potential
You can use Star Crystals or Star Fragments to grant a Potential to a Potential Slot. You can randomly grant effects that increase the entire party's HP, all Attack, or Defense by a percentage, and you can overwrite the effect by granting potentials repeatedly. The maximum Potential Slots differ by pet rarity, with Rare Pets having up to 3 slots and Legendary Pets having up to 4.
9. Pet Skill Enhancement New!
The Pet Skill Enhancement System is a new feature that allows you to improve the effects of your 6★ pets. By using Skill Enhancement Stones or Brilliant Skill Enhancement Stones, you can gain a strategic advantage in battle. A new Enhance Skills menu has been added to Grow Pets.

| Superb Egg x1 | Quality Egg x5 + Gold x2,000 |
Lower Grade eggs can now be exchanged for higher-grade eggs by using Gold and additional eggs through the Material Exchange feature
Hatch
Hatching eggs is the main way to obtain pets. Once you get an egg, go to Grow Pets > Hatch to register and hatch it. The appearance rate of each pet differs depending on the type of egg. By leveling up your Adventurer Skill, you can increase the number of egg hatching slots to a maximum of four.
Hatch Expansion
The number of Pet Eggs that you can place in Hatch Slots will be expanded from 4 → 10. The expansion slot will be based on your Adventure Level.
| Slot Added upon Reaching Adventure Level |
| Lv. 26, 31, 36, 41, 46, 51 |
Approximate Hatch Rates for Each Egg Type
| Legendary Egg | Superb Egg | Quality Egg | Common Egg | |
| Legendary 4★ | 100% | 0.8% | 0% | 0% |
| Rare 4★ | 0% | 9.2% | 1% | |
| 3★ | 67% | 51% | 5% | |
| 2★ | 23% | 14% | 25% | |
| 1★ | 0% | 34% | 70% |
Examples of How to Obtain Eggs
| Type | Example of How to Obtain |
 Legendary Egg | - Topaz Exchange Shop (Topaz x5000) |
 Superb Egg | - Guild Exchange Shop (Guild Token x500) - Guild War Exchange Shop (Pendant of Glory x80) - General Store (Ruby x80/Gold x70,000) - Event Shop - Event Missions - Material Exchance |
 Quality Egg | - Gold Exchange Shop (Gold x25,000) - Guild Exchange Shop (Guild Token x200) - General Store (Gold x20,000) - Event Missions - Material Exchance |
 Common Egg | - Gold Exchange Shop (Gold x15,000) - Guild Exchange Shop (Guild Token x100) - General Store (Gold x10,000) - Event Missions |
Eggs can be obtained from various shops and event missions. The items in the General Store are random, so be sure to check it every 12 hours.
Fusion
You can fuse two pets of the same rank as materials to get a pet of the same or one rank higher. Although the probability is low, it's worth trying to fuse 4-star pets using 3-star pets as materials.
Pet Fuse Slot Expansion
The number of Pet Fuse Slots that you can place in Pet Fuse will be expanded from 5 → 10. The expansion slot will be based on your Adventure Level.
| Slot Added upon Reaching Adventure Level |
| Lv. 36, 41, 46, 51, 56 |
Crafting
You can craft four 4-star pets or five 6-star Rare pets into a random box that contains a 4-star Legendary pet or a specific Rare pet.The cost is high, but Crafting is also effective if you are focusing on training specific Rare pets that can be crafted.
Pet Crafting Update New!
| Crafting Type | Acquired Item | Crafting Material |
|---|---|---|
| Fixed Crafting [Legendary] | 4★ Legendary Pet Selector x1 (Once a month) | 4★ Legendary Pet x3 |
| Random Crafting [Rare] | 4★ Legendary Pet Ticket x1 (Once a month) | 4★ Rare Pet x10 |
The Pet Crafting menu has been updated with two new crafting options, each available once per month. You can now perform Fixed Crafting to acquire a 4★ Legendary Pet Selector using three 4★ Legendary Pets , or opt for Random Crafting to obtain a 4★ Legendary Pet Ticket by consuming ten 4★ Rare Pets.
Summon
You can also perform a Pet Summon using Pet Summon Tickets or Rubies. If you're using Rubies, Hero Summon has a higher priority, but if you have tickets saved up or have extra Rubies, you should try Pet Summon as well.
Pet Wish Summon
The 11/13/2025 update includes a new summon that allows players to select a desired pet, similar to the Hero Wish List. This summon requires Pet Wish List Summon Vouchers, which can be obtained from content such as Infinite Tower, Tower of Trials, and Adventure-Nightmare star clears.
In addition to the new Pet Wish Summon, players can receive 100 Pet Wish List Summon Vouchers by redeeming the coupon code SENAGIFT2025.
Shop Purchase
You can also obtain pets by purchasing items that come with them, like the 5-Star Croa Pack, from the paid shop. If you don't mind spending money, consider making a purchase.
Pet Additional Tips
Don’t Focus on Pets in the Early Game
It’s best to start raising pets only after you’ve obtained a Legendary Pet from Gacha, Eggs, or Fusion. Rare 4★ Pets are just temporary options until you secure a Legendary, so there’s no need to use Power Ups. Even evolving the free 5★ Croa to 6★ doesn’t give a significant improvement compared to the cost.
Prioritize Hero Growth First
In the early and mid game, strengthening your Heroes has a far bigger impact than raising Pets. Focus on gearing and leveling Heroes first, then shift resources into Pets later.
How to Upgrade Heroes and Pets
Use Low-Star Pets for Fusion
Use 1–3★ Pets obtained from Eggs as Fusion materials. Even if Fusion fails, you can reuse them as materials again, aiming to eventually obtain a Legendary Pet. Avoid using these as Enhancement Materials for higher-star Pets.
Enhance Only Legendary Pets
Once you have a Legendary Pet, that’s when you should begin Powering it Up. Only use materials that provide at least a 25% success rate. Considering how hard Pets are to get, it’s better to avoid using Enhancement Materials. Instead, raise their rarity through Fusion first.
Save Resources for Long-Term Pets
Don’t waste Gold, Rubies, or rare materials on Pets you’ll eventually replace. Save them for when you secure a Legendary Pet you plan to keep for the long term.
Maximizing Pets Through Bond and Potential
The true value of Pets lies in their Bond effects and Potentials, which only become available at 6★. Focus on raising your Pet’s Bond first to open all four Potential slots before aiming for specific effects. Since Potentials are random, repeatedly rerolling can consume resources very quickly.
