Breeding

Breeding can be performed in the Breeding Yard near the player's house on the Ranch.

You can breed all your tamed Nephelym with each other or yourself (originally, not every pair had a sex animation, but the breeding happened regardless; the June 2021 revision added animations for all sizes).

Successful breeding will result in a Pregnancy for the receiver, which last three in-game days. The chance of pregnancy is a % chance equaling the sum of the breeding partners' Fertility Stat. For example, if one Nephelym's Fertility Stat is 10 and the other's is 15, the chance of pregnancy when those two Nephelym breed is 25% (50% if one or both have the Fertile Trait). The maximum chance of success is 80% (12.5% if incest).

The offspring of two different species of Nephelym is either a species of one of their parent with Traits form both of their parents, or a Hybrid, which can't be captured in the Wild.

There is a 30% chance that the offspring is a Hybrid if:
 * the parents are compatible to produce a Hybrid
 * you bought the Mutt Hut form Cassie (it costs 2400 Orgasium)
 * the Hybrid is toggled on in the fetishes tab.

You only start with the Doggy position, and have to buy the others from Pawsmaati, who can be found at Sultry Plateau.

Experience gain and levels
When two Nephelym have sex both gain XP. When they have gained enough XP they will gain a level, up-to a maximum level of 100.

When a Nephelym gains a level they will gain stats according to the table to the right. When a Nephelym gains a level they will gain +1 to each stat. Furthermore, at every level divisible by 5

(5, 10,15, 20 ...) the max lust increases by 200.

The XP gained for both partners is calculated as follows: (Level of giver) * (Level of receiver) * Modifiers.

Modifiers are traits. Hedonist, sadistic kindhearted, meaty and charmer are the current list of traits that give XP modifiers.

Positions
The breeding sex scene depends on the sizes and position of the giver/receiver. The Pairs with Scene Chart represents what sizes or receiver and giver are compatible with the position's animation by the following abbreviations: T = tiny, S = small, N = normal, L = large, H = huge, and M = massive. If a couple have sizes (or physiology) that are not compatible with the scene, the breeding will resolve, but there will be no animation, similar to selecting the Quick option.

Trivia

 * Two kindhearted Nephelym having sex together will gain 150% XP, which is not obvious from the description of the trait.
 * Bats are not classified as compatible givers for the Lifted position, even if they posses an Atypical trait that would make them a compatible size the animation will not play, presumably due to a distinct lack of arms.
