Bases make up a large part of your wolf's appearance! This is the color of their fur underneath any markings, mutations, or decorations. There are many possible bases, each sorted into categories called genetics. These genetics determine how the bases interact with each other when breeding!
Every base, with the exception of Special bases, has three categories of genetics: Color, Shade, and Rarity. Special bases only have a Color and Shade, and not a Rarity. You can view a wolf's base and base genetics under the Looks section of their page. Here, their base color will be listed above their base genetics. Each base has set associated genetics that cannot be changed. For example, the Onyx base will always have the Monochrome Dark II genetics, and will never be Cool Medium I or anything else.
In the example above, "Muted Dark II" is the base genetics of the base, Pecan. This is the base's full genetics, read in the order of Color Shade Rarity. If the base is a combo base, detailed later in this page, it will be indicated next to the base's genetics.
The percentage in parentheses next to the wolf's base name is the percentage of wolves in the game that also have that base. So, in this screenshot, 0.36% of all wolves in the game have the Pecan base.
Breeding bases is not a matter of "this base x this base = that base". In breeding, all three of the genetics categories act independently of one another to provide a pool of possible base results. You will never be guaranteed exactly one or two bases when breeding, only one or more bases from a pool generated based on the parents' base genetics. You will be guaranteed a random base in one or more genetics categories, such as Cool Light I, with the exact categories possible being dependent on the parents' base genetics. Every breeding also provides the chance for a pup to get the parent's exact base, except for in combo base breeding, detailed later in this page.
Color
Color
The first category of base genetics is the Color. This categorization refers to the general appearance of the base. Most bases will be sorted into one of four options: Cool, Muted, Warm, or Monochrome. An additional category, Special, is used only for applicator bases from events, which will be given the Special label even if another category applies to them as well. If the base is cool-toned, it will fall in the Cool category, while warm-toned bases will fall in the Warm category. Black, gray, or white bases will be classified as Monochrome. Generally, brown or beige bases will be sorted in the Muted category. However, Muted bases can also encompass softer versions of some warm tones.
Breeding similar colors together will help make breeding outcomes more predictable. For example, breeding a Cool base with another Cool base will guarantee Cool-based offspring. Each color combination interacts uniquely in breeding to produce a variety of results.

The second category of a base's genetics is its shade. This refers to how vibrant the base is between the options of Light, Medium, and Dark. Each color group has bases of each shade, such as Cool Medium or Warm Light bases. Shades interact with each other in breeding to provide one or more possible base shade results.

Rarity Tier
Rarity Tier
The final category of a base's genetics is its rarity tier. Every base has a tier besides Special bases, which will have a * in place of a tier number to represent that it does not have a rarity. The rarity tier reflects how difficult the base is to breed. A tier of I means that it is common and easy to breed, while a tier of III means that it is rare and difficult to breed.
It is not possible to breed a base higher than the rarity tiers of the parents. For example, two tier II parents cannot produce a tier III child.

Base Breeding
Base Breeding
The most important concept to remember when breeding bases together is that, with the exception of combo and special bases, a base's genetics is the only thing that affects breeding. Breeding bases together is not a matter of "this base x this base = that base". Rather, it's "these genetics + these genetics = those genetics". There are minor exceptions to this rule present while breeding Special and Combo bases which require a parent to have a specific base in order for the base to be passed down. However, outside of being able to pass itself, a Special or Combo base's genetics will still be the only contributing factor for what else is possible from the breeding.
Bases do not have "fail" colors like eyes do, since breeding outcomes are determined by the interaction of their genetics and not by the base color itself. Any result from breeding two bases together will be randomized from a pool generated based on the interaction between each parent's base genetics.
The pass rates of most base combinations is a mystery, never revealed by developers. Generally speaking, higher tier bases and Special bases are the most difficult bases to breed and have very low pass rates. There are some confirmed values that we can share detailed below.
Special Bases
Special Bases
Unlike other bases, Special bases can only be obtained through breeding if one of the parents has the same specific Special base. A wolf with a Special base cannot produce any Special base other than its own. Do note that Special bases do not have a rarity, and are not a tier, hence their tier being represented by a *. When this page refers to "any tier", Special bases are excluded from this. Special bases are completely separate from each other and do not share any overall tier category.
Breeding two different Special bases together has the chance to fail to any color group and rarity, though the shades of the Special bases are taken into consideration when determining which bases can be produced. A Special base bred to a base of a different color group has the chance to either produce that Special base, or any base within the color group of the other parent. For example, a Special x Cool pairing will fail to Cool bases only.
When breeding two Special bases together, there is a 5% chance that a pup will get a Special base. If the parents have the same Special base, the pup has a 5% chance to get that same Special base. If the parents have different Special bases, the pup has a 5% chance to get either the mom’s base or the dad’s base.
Examples of Special Base Breedings
Special Light + Special Light
Any Light base from any category besides Special, with the exception of the parents' bases
Special Light + Special Dark
Any base in game besides Special, with the exception of the parents' bases
Special Light + Warm Light I
Any Warm Light base, and the parent's Special base
Special Dark + Monochrome Medium II
Any Monochrome Medium or Monochrome Dark base, and the parent's Special base
You cannot breed any normal bases together to get a Special base. For example, you cannot breed two Tier III bases together to get a Special base. In order to breed a specific Special base, one of the parents must have that specific base.
The only Special bases currently available are obtainable using applicators purchased or obtained during events. You can view all Special bases on the Applicator Bases page.
Combo Bases
Combo Bases
Combo bases are an extra-rare category of Special base which have very specific requirements to be bred. These bases must be bred using specific bases, called "factors", which combine to form the combo, similar to combo markings. They cannot be bred with similar genetics like regular bases can-they must be bred using factors!
You can tell if a base is a combo base by looking at its genetics on a wolf. So far, there are only four combo bases originating from the Lunar Event: Diaelum, Glownoise, Moonloss, and Selunia.
On top of having a very small chance of being bred, combo bases originating from the Lunar Event may only be bred at night. If you breed two factors together during any other time of day on Wolvden, a combo base will not be possible!
When being bred regularly, combo bases use the same genetics rules as any other base. For example, if a combo base is a Special Dark base, it will breed the same way as any other Special Dark base. However, it may only pass itself if it is being bred to itself or one of its factor bases. Below are some examples of combo base breedings.
Examples of Combo Base Breedings
Factor Base + Factor Base
Typical results based on each parent's genetics, very small chance for combo base
Combo Base + Factor Base
Typical results based on each parent's genetics, very small chance for combo base
Combo Base + Non-Factor Base
Typical results based on each parent's genetics, NO chance for combo base
You can learn more about combo bases on the designated Combo Bases page.
Breeding Bases with Matching Categories
Breeding Bases with Matching Categories
Breeding bases with matching categories, being the same color group, shade, and rarity, result in those specific bases having an additional 25% chance, on top of the chances presented with normal genetics, of passing directly to the pup. If the bases bred have the same color group and shade, but not the same rarity, the additional chance drops based on how far the rarities are apart. If the rarities are one step apart, the additional chance will be 5%, while if the rarities are two steps apart, the chance will be dropped to 0.5%.
For example, if you breed a Warm Medium I base to a Warm Medium III base, there will be an additional 0.5% chance on top of normal pass rates that the pup produced will have the same base as one of their parents. If you breed a Warm Medium II base to a Warm Medium III base, there will be an additional 5% chance for either base to pass directly to the pup. Finally, if you breed two Warm Medium IIIs together, there is an additional 25% chance for the pup to get either of the parents' bases.

Every base can be obtained through breeding the right bases together, so we won't list Breeding as a source for all bases, but just keep in mind that it's implied! You can view these bases sorted by method of obtention and with full-body previews on the Base Catalogue page.

Interested in one of the bases marked as "Breed-Only"? While a breeding isn't guaranteed to result in an exact base, there's some ways that you can increase your chance of getting the one you're looking for. Try to match the base's genetics when breeding as closely as possible. If you're aiming to breed a Breed-Only Warm Medium II base, try pairing other wolves with Warm Medium II or Warm Medium III bases.
