Mythic pets are the ultimate goal in Build a Base and Steal. They have the highest base rates, the strongest special abilities, and the most valuable passive income contribution. But they are also the rarest, with drop rates below 0.01% in standard rolls. Obtaining a mythic is not a matter of luck; it is a matter of strategy, patience, and resource management. This guide breaks down the math behind mythic drop rates, the most effective rolling strategies, and the evolution path that can bypass rolling altogether.
Mythic Drop Rates Explained
The base drop rate for mythic pets in Build a Base and Steal is 0.01% in standard rolls. This means that, on average, you need to roll 10,000 times to see one mythic. In practice, the drop rate is slightly higher for some pets and slightly lower for others, because the developers weight the drop rates based on the pet's power level. The Eternal Phoenix, for example, has a drop rate of roughly 0.01%, while the Cosmic Dragon has a drop rate of roughly 0.015%, because the Phoenix is stronger than the Dragon.
The drop rate is not constant. It is affected by three factors: the pity system, event bonuses, and premium modifiers. The pity system guarantees a mythic after a certain number of non-mythic rolls, but the pity counter resets when you obtain a mythic. Event bonuses multiply the drop rate by 2-5x during themed events. Premium modifiers multiply the drop rate by 1.5-2x for players who have purchased the premium pass. The combined effect of these factors can increase the effective drop rate from 0.01% to as high as 0.1% in optimal conditions.
The Pity System in Detail
The Build a Base and Steal pity system works on a per-server basis. Each server maintains a counter that tracks the number of rolls since the last mythic drop. When the counter reaches a threshold, typically between 5,000 and 10,000 rolls depending on server settings, the next roll is guaranteed to be a mythic. The pity counter is shared across all players in the server, which means that a single player who rolls heavily can trigger pity for the entire server and then another player, who may have rolled only once, gets the guaranteed mythic.
The pity system is designed to prevent runs of bad luck, but it also creates a strategic opportunity. The optimal strategy is to roll heavily during the first half of the pity cycle, when the drop rate is at its base, and then reduce rolling during the second half, when the pity counter is high and the next mythic is imminent. Let other players trigger pity for you, and then you can obtain a mythic with a single roll when the counter is near the threshold.
Rolling Strategies for Mythics
The Event Chasing Strategy
The most effective rolling strategy for mythics is to chase themed events. During a Phoenix-themed event, for example, the drop rate for the Eternal Phoenix increases to 0.05-0.1%, which is 5-10x higher than the standard rate. The event also increases the drop rate for Phoenix evolution materials, which makes it easier to evolve a Phoenix to mythic if you obtain a legendary. Rolling during an event is the single highest-leverage action you can take to obtain a mythic.
The optimal event strategy is to save your rolling budget between events and then spend it all during the event window. Do not roll a small amount every day; roll a large amount during the event, when the drop rate is multiplied. The event window is typically 3-7 days, and the drop rate multiplier is only active during that window. Rolling outside the event wastes resources on a lower drop rate.
The Premium Strategy
The premium strategy is for players who are willing to spend real money to accelerate their progress. The premium pass in Build a Base and Steal provides a permanent 1.5-2x multiplier to mythic drop rates, and it also provides additional rolling currency each day. The premium strategy is to purchase the pass as early as possible and then roll consistently every day, relying on the increased drop rate to produce mythics over time.
The premium strategy is less effective than the event strategy for new players, because the premium multiplier is constant, while the event multiplier is temporary but much larger. The premium strategy shines in the long run, however, because the premium pass is permanent, and the increased drop rate compounds over months of consistent rolling. For players who commit to the game for the long term, the premium pass is eventually worth the cost.
The Server Hopping Strategy
The server hopping strategy exploits the pity system by moving between servers to find servers where the pity counter is high. The strategy works as follows: join a new server, check the pity counter in the recent-activity feed, if the counter is below 2,000, move to a different server, if the counter is above 5,000, stay in the server and roll until pity triggers, then move to a new server. By only rolling when the counter is high, you maximize the number of mythics obtained per roll.
The drawback to server hopping is that it is time-consuming and it requires a good understanding of the pity system. The recent-activity feed only shows the number of rolls since the last mythic, not the exact pity counter, so you have to estimate. Additionally, server hopping can be disruptive to your base building and offline income, because each new server has a different configuration of auras and pets. For players who care more about base building than about obtaining mythics, server hopping may not be worth the disruption.
Evolution Path to Mythic
Rolling is not the only way to obtain mythics. The evolution path allows you to upgrade a lower-rarity pet to mythic without ever rolling a mythic. The evolution path is expensive in terms of materials and cash, but it is guaranteed, which makes it attractive for players who have bad luck with rolling or who want to avoid the variance of rolling altogether.
Evolution Step 1: Common to Uncommon
The first evolution step, from common to uncommon, costs a small amount of evolution dust and cash. The cost is negligible for most players, and the evolution provides a 50% increase in base rate. For players who have obtained a strong common pet, such as one with a percentage-based special ability, evolving it to uncommon is usually worth it, because the increased base rate amplifies the effect of the ability.
Evolution Step 2: Uncommon to Rare
The second evolution step, from uncommon to rare, costs a moderate amount of evolution shards and cash. The cost is significant for early-game players, but the evolution provides another 50% increase in base rate. For players who have invested time in leveling the friendship of a pet, evolving it to rare preserves that investment and provides a meaningful stat boost.
Evolution Step 3: Rare to Epic
The third evolution step, from rare to epic, costs a significant amount of evolution crystals and cash. The cost is high enough that most players will only evolve a handful of pets to epic. The evolution provides another 50% increase in base rate, which makes epic pets viable in the mid-to-late game. For players who are close to reaching the offline cap, evolving a pet to epic can extend the time it takes to hit the cap, which increases daily income.
Evolution Step 4: Epic to Legendary
The fourth evolution step, from epic to legendary, costs a massive amount of evolution essence and cash. The cost is prohibitive for most players, and only the strongest pets should be evolved to legendary. The evolution provides another 50% increase in base rate, which makes legendary pets competitive with top-tier pets from rolling. For players who have obtained a strong epic pet through evolution or through rolling, evolving it to legendary is usually worth it, because the legendary form becomes a centerpiece of the roster.
Evolution Step 5: Legendary to Mythic
The fifth evolution step, from legendary to mythic, costs an enormous amount of evolution stars, cores, and cash. The cost is so high that most players will only evolve one or two pets to mythic over the course of their career. The evolution provides another 50% increase in base rate, which makes mythic pets the strongest in the game. For players who have obtained a strong legendary pet and have collected the rare materials from boss encounters, evolving it to mythic is the ultimate achievement in Build a Base and Steal.
Combining Rolling and Evolution
The optimal strategy for obtaining mythics is to combine rolling and evolution. Roll heavily during events to obtain legendary pets, then use evolution materials from boss encounters to evolve those legendaries to mythic. The combination leverages the strengths of both methods: rolling provides a steady supply of potential evolution targets, and evolution guarantees that the strongest targets reach mythic.
For most players, the optimal path is to evolve 3-5 pets to mythic over the course of their career. Evolving more than that is rarely worth the material cost, because the marginal benefit of additional mythics decreases once you have a core roster of mythics. The evolution path is a long-term goal, not a short-term grind, and the players who reach the endgame are the ones who play consistently over years rather than over weeks.
The Mythic Endgame
The mythic endgame in Build a Base and Steal is the state where your roster consists entirely of mythic pets with maxed friendship levels and percentage-based special abilities. At this point, the progression system is effectively complete, and further improvement comes from refining your base configuration rather than from obtaining new pets. The income at this level is massive: a full roster of mythics can generate enough income to buy a new mythic outright every week without any additional rolling.
Reaching the mythic endgame takes months of consistent play, because the drop rates for mythics are extremely low and the material cost for evolution is enormous. Most players will never fully complete the mythic endgame. Instead, they will obtain 3-5 mythics through a combination of rolling and evolution, and then focus on optimizing their base configuration to maximize the income from those mythics.
The mythic endgame is the final destination of the Build a Base and Steal progression system. It is not for everyone, and it requires an enormous time investment. But for the players who commit to the journey, the reward is a base that generates massive passive income and a roster of the strongest pets in the game.
