Breeding Legendary Dwellers in Fallout Shelter is a matter of luck and patience rather than a guaranteed strategy. However, you can increase your chances of breeding a Legendary Dweller by understanding how the game calculates your chances of birthing a baby of a specific rarity by the two Dwellers you choose as parents. Here’s a comprehensive Fallout Shelter breeding guide that covers how to breed Legendary Dwellers.
How to Breed Legendary Dwellers in Fallout Shelter
To begin with, let me explain the probability of breeding a Legendary Dweller in Fallout Shelter and how the formula for calculating those chances works. Understanding these two aspects of birthing Dwellers will give you a clear understanding of what you need to do and why you need to do it to improve your chances.
Here are the birthing chances for each rarity in Fallout Shelter:
- Common: 80% (parents with combined stats lower than 122)
- Rare: 13.33% (parents with combined 122 stats or higher)
- Legendary: 6.67% (parents with combined stats of 134)
Here is the formula that the game uses to calculate these chances:
- max = (male_total_special + female_total_special – 14) / 126
- value = random(max / 4, max)
The key to increasing your chances of birthing a Legendary Dweller in Fallout Shelter is selecting parents with high S.P.E.C.I.A.L. stats. Basically, you want to choose two parents with a total of 134 combined stats, the combined maximum stats that two parents can have. The higher the stats, the higher the chances they will give birth to a higher rarity baby. Therefore, it’s crucial to pair up Dwellers with high stats until you achieve the desired result of breeding a Legendary Dweller in Fallout Shelter.
It’s important to note that the game does not include S.P.E.C.I.A.L. stats obtained from outfits worn by your Dwellers with the stats used in the above formula. Therefore, you must use your parents’ natural stats when breeding. If you need to improve the stats of one or both parents, you can train them in specific rooms to increase those stats until they reach the combined maximum stats of 134.
