RO PetWindow
The Cute Pet System, or Pet System for short, allows adventurers to tame monsters to become personal pets. Once pets, these monsters will grant special bonuses to their owners when raised to be Cordial or Loyal. Each pet presents its own difficulty in capturing and raising.

Taming a Pet

To turn a monster into a pet, players must first obtain a pet tame. Each tamable monster has a specific item it can only be tamed with.

  1. Once you have the taming item of the monster you wish to tame, seek out the monster on a map it spawns on.
  2. Double-click on the tame to turn your arrow cursor into a targeting cursor (halo icon). Carefully click on the monster with the targeting cursor to begin the taming process. (NOTE: It's best to attempt this on a monster that is alone with no other monsters around it in order to prevent mis-clicks, as mis-clicking will consume the taming item whether or not you clicked on the monster.)
  3. If done correctly, a slot machine will appear in the center of your screen. Click on the slot machine to slow it down.
  4. If the slot machine lands on "Success," you will obtain the egg of the monster you wish to tame. If the machine lands on "Fail," you will receive nothing. The taming item will be consumed whether or not you succeed.

Raising a Pet

Once you've obtained a monster egg, you must now purchase a Pet Incubator in order to hatch it. After hatching, you must continually feed the pet with its corresponding Food in order to keep it from running away. Each pet has different hunger tolerances so not every pet will require the same feeding time (i.e. one pet needs to be fed every 5 minutes while another has to be fed every 9 minutes, etc.)

Feeding a pet not only keeps it from running away, but also levels up its intimacy level. There are 5 intimacy levels:

  • Awkward
  • Shy
  • Neutral
  • Cordial
  • Loyal[1]

Each pet starts out Neutral upon hatching and its bonus becomes activated upon reaching Loyal intimacy. To retain a pet's intimacy without feeding it, you can return it to its egg and hatch it again with another Pet Incubator.

In the beginning, certain pets were developed to do certain actions (e.g. Pet Porings can loot for their owners, etc.) when they were raised to be Cordial or Loyal. That was eventually dropped in favor of having them provide stat bonuses to their owners.

Naming Your Pet

An optional feature of the Cute Pet System is the ability to name your pet. You can only name your pet once and it cannot be renamed no matter what.

Once a pet is named, the "Beloved" prefix will be appended to its item name after being returned to its egg (i.e. a Baby Desert Wolf Egg will become a Beloved Baby Desert Wolf Egg after being named).

Dressing Your Pet

Each pet has a special accessory item that can be used to dress it up. The accessory can be equipped and unequipped at will. The accessory can remain on the pet even when put back into its egg.

NOTE: Not all pets have its own accessory item.

Pet Evolution

With the implementation of the pet evolution update, players can now evolve their pets from their baby forms to their adult forms or their adult forms to their enhanced forms.

Currently, the following pets can be evolved:

  • Poring → Mastering → Angeling
  • Pecopeco → Grand Peco
  • Orc Baby → High Orc
  • Savage Babe → Savage
  • Isis → Little Isis
  • Drops → Eggring
  • Yoyo → Choco
  • Dokebi → Am Mut
  • Bongun → Hyegun
  • Lunatic → Leaf Lunatic
  • Nine Tail → Cat o' Nine Tails
  • Deviruchi → Diabolic
  • Petit (Ground) → Deleter (Ground)

Evolved pets will take longer to reach Loyalty, but they will lose intimacy much less and get hungry less often. In addition, evolved pets will enable an auto-feeding system so you'll never lose your pet again![2]

Evolution Bonuses

In addition to changing their appearance, evolved pets will also give better bonuses depending on their intimacy.
