This tool assists players of the Black Desert Online (BDO) game in predicting the potential outcomes of breeding horses. It typically takes into account factors such as the tier and level of the parent horses to estimate the tier and gender of the foal. As an illustration, a player might input that a level 30 Tier 6 female horse is being bred with a level 30 Tier 5 male horse; the calculator then provides a probability distribution of the resulting foals tier.
The utility of such a tool stems from the complexity and somewhat unpredictable nature of the horse breeding system within the game. Horse breeding is a significant activity, enabling players to obtain faster and higher-tier steeds for transportation and combat. Using a predictive instrument allows for more informed decision-making, potentially saving resources and increasing the likelihood of acquiring desirable horses. Historically, players relied on anecdotal evidence and trial-and-error, making the development of these calculators a valuable community contribution.
