Fields of Mistria breeding requires two compatible animals with at least two hearts each. You also need the Heart Shaped Treat that matches their species. The resulting color system has six tiers, with four season based colors in Tier 6.
Breeding Requirements
Both compatible animals must have two hearts or more before they can breed. The process also requires a Heart Shaped Treat for the corresponding species. The supplied material does not identify where the treat is obtained, how much it costs, or whether its recipe must be unlocked.
The current Mistria Guide breeding page does not publish a Heart Shaped Treat price, shop, or recipe route. Do not substitute a similarly named item or assume that one species treat works for every animal. This guide confirms only that the treat must correspond to the species being bred.
The approved breeding page uses the word compatible without defining every allowed pairing. It does not publish species matching, sex restrictions, shared housing rules, feeding timing, or pregnancy handling. This page does not add those rules from memory or from an unapproved source. Check the current in-game breeding prompt before using the treats.
Incubation, Adulthood, and Color Tier Table
Every animal in the collected table has a three day incubation or birth period. Capybaras, Chickens, Ducks, and Rabbits take three days to reach adulthood, while Alpacas, Cows, Horses, and Sheep take five days. The tier columns report the number of colors available to each species at each level.
| Animal | Incubation or birth | Adulthood | Tier 1 | Tier 2 | Tier 3 | Tier 4 | Tier 5 | Tier 6 |
|---|---|---|---|---|---|---|---|---|
| Alpaca | 3 days | 5 days | 3 | 3 | 3 | 1 | 1 | 4 |
| Capybara | 3 days | 3 days | 3 | 3 | 3 | 1 | 1 | 4 |
| Chicken | 3 days | 3 days | 3 | 3 | 3 | 1 | 1 | 4 |
| Cow | 3 days | 5 days | 3 | 3 | 3 | 1 | 1 | 4 |
| Duck | 3 days | 3 days | 3 | 3 | 3 | 1 | 1 | 4 |
| Horse | 3 days | 5 days | 6 | 3 | 3 | 1 | 1 | 4 |
| Rabbit | 3 days | 3 days | 3 | 3 | 3 | 1 | 1 | 4 |
| Sheep | 3 days | 5 days | 3 | 3 | 3 | 1 | 1 | 4 |
Horse is the only species in the table with six Tier 1 colors. Every other listed species has three Tier 1 colors. All eight species share three colors in Tier 2, three in Tier 3, one in Tier 4, one in Tier 5, and four in Tier 6.
How the Six Color Tiers Are Structured
Each listed animal species uses Tiers 1 through 6. The table confirms the number of available colors at every tier, but it does not provide the name or appearance of any individual color. This page therefore does not label palettes, markings, or visual examples that are absent from the approved source.
Tier counts alone do not establish the exact parent combination needed to reach the next tier. The current Mistria Guide breeding page does not publish inheritance percentages, guaranteed outcomes, or rules for choosing between parent colors. No probability claim is added to this version of the guide. Use the table only to compare the number of colors at each tier.
The shared shape of Tiers 2 through 6 makes the table easy to scan across species. Horse differs only in Tier 1 count, while all other listed rows use the same counts throughout. This comparison describes available color counts and does not claim that the route to each tier is identical.
Tier 6 Seasonal Colors
Tier 6 contains four season-specific colors for each listed species. The current approved source confirms the count but does not name each color or state whether conception season or birth season selects the result. This guide therefore does not assign a timing rule to a Tier 6 outcome.
The table confirms four Tier 6 options but does not name them. Their exact colors, patterns, and in-game labels are not published on the approved breeding page as of August 11, 2026. No additional weather, festival, or location requirement is asserted here.
Plan Tier 6 attempts only with the confirmed fact that four seasonal variants exist. The approved source does not state how a season change during the three-day period is handled. Follow the current in-game result until a permitted source publishes the selector rule.
Planning Around Growth Times
All eight species use the same three day incubation or birth period in the collected table. The adulthood period then separates them into two groups. Capybara, Chicken, Duck, and Rabbit reach adulthood in three days, while Alpaca, Cow, Horse, and Sheep reach adulthood in five days.
Use the adulthood column when estimating how long a newborn remains immature. The source presents incubation and adulthood as separate columns but does not define exact day boundaries or the time of day when a stage changes. This page reports the two published fields separately and does not combine them into a more precise countdown.
Verified Scope and Source Limits
The approved source does not document how to obtain or purchase Heart Shaped Treats. It also omits specific color names, visual swatches, parent pairing rules, and inheritance chances. Those fields remain outside this guide and any definitive breeding calculator as of August 11, 2026.
The confirmed planning core is limited to the two heart requirement, species matched treat requirement, growth table, six tier structure, and seasonal Tier 6 rule. These facts are recorded for game version v1.0.2 in the supplied material. Future patches should trigger a fresh check of requirements, times, tier counts, and seasonal behavior.
