Pet Fusing

Pet Fusing is an action which takes place in the Pet Yard, wherein two pets of the same family and rarity are combined to create one new pet of the next rarity level. Your pet yard must be at least one tier above the pets you intend to fuse, in order to be able to attempt a fusion with those pets. You are not able to fuse pets of different rarities and/or families. However, it is possible to change a pet’s family using the Pet Wardrobe, at a cost of 1000 Fame or 100 Gold.

Fusing Process

Accessing the Interface
Access the pet fusing interface by talking to the yard caretaker in the Pet Yard, and then clicking on the “Fuse” tab in the lower right corner of the interface. You should see a screen very similar to what is shown below.

The left side of the interface shows all of your current pets. Click on the pet you intend to receive the benefits of the fusion. This pet will remain after the fusion. Once you have selected your recipient pet, the lower right corner of the interface will show every pet that is compatible with the recipient pet. The pet you select in the lower-right corner will be consumed in the fusion process.

Once you have selected your recipient pet and “catalyst” pet, click your payment option (fame or gold) to fuse the pets into one new pet of the next rarity.

Pet Rarity Fusing Cost (Fame) Fusing Cost (Gold)
Common 300 100
Uncommon 1000 240
Rare 4000 600
Legendary 15000 1800
Evolving Pet

The Results

These characteristics will be determined for the resultant pet when you fuse:

  • Abilities: The abilities and arrangement of abilities are retained from the recipient pet you selected.

  • Ability Levels: The initial levels of your new pet’s abilities are determined by the levels of both recipient and catalyst pets before fusing. If the abilities’ levels are mismatched, the resultant pet will have a level that is the average of the two numbers, rounded down. For example, if a recipient pet has level 50 in its second ability but the catalyst pet’s second ability is only level 45, the resultant pet will have level 47 in the second ability.

  • Level Caps: The maximum level for your resultant pet’s abilities is determined by the levels of the first abilities of both recipient and catalyst pets. If both pets’ first abilities are maxed, then the ability level cap of the resultant pet will be at its highest possible level. The levels of the second and third abilities have no factor in determining the level cap of the resultant pet.

Example of level determination via fusing:

Fusing also unlocks the pet’s additional abilities. Although all of the abilities of your pet are predetermined, a common pet will only have one functioning ability. When you fuse two commons into an uncommon, the second ability will be unlocked. In order to unlock the third ability, the pet will need to reach the Legendary rarity level.

The level cap for all of the unlocked abilities in the resultant pet will be the average of the two pets’ first abilities +20. It was mentioned before that the resultant pet will have the max possible ability cap if both recipient and catalyst pets have a maxed first ability. However, if the first abilities on either pet are not maxed, the averaging and rounding rules mentioned before will apply to the first ability, and the level cap of the resultant pet is determined likewise. It is recommended to at least max both pets’ first abilities before fusing. It is also more cost efficent to completely max both pets before fusing them.

When fusing pets to the rare or divine tier, their appearance will change. The results mentioned above apply in exactly the same way, but the new pet will have a different aesthetic. The aesthetic change is reversible by spending 200 Fame or 20 Gold in the Pet Wardrobe, should you prefer how the pet looked beforehand.

Hatched eggs have the same number of unlocked abilities (and caps) as their fused counterparts. The first ability is always at the best initial level for the rarity of the pet, but the second and third levels can vary significantly. The cost to raise a hatched pet of a higher rarity could be higher than if you had started a pet from the common or uncommon tiers. When determining the best course of action for your desired pet, remember to consider the cost per feeding, the cost to fuse, and the feed power per feeding in order to make the most comprehensive comparison.
