Gear crafting in Build a Base and Steal is the guaranteed path to high-tier gear. While rolling relies on luck, crafting relies on grinding for materials, and a dedicated player can craft any item in the game given enough time. The crafting system is complex, the materials are rare, and the costs are high, but the result is a guaranteed high-rarity item without the variance of rolling. This guide breaks down the crafting mechanics, the materials required for each tier, and the optimal crafting strategy.
How Crafting Works
Crafting in Build a Base and Steal is a three-step process. First, you obtain the base item of the previous rarity — for example, a legendary hammer to craft a mythic hammer. Second, you collect the crafting materials required for the upgrade. Third, you pay the crafting fee in cash and wait for the crafting timer to complete. The crafting timer varies by rarity: uncommon upgrades take 1 hour, rare upgrades take 6 hours, epic upgrades take 24 hours, legendary upgrades take 72 hours, and mythic upgrades take 168 hours (7 days).
The crafting timer can be skipped using premium currency, but the cost is high. Skipping a mythic upgrade costs more than the item itself is worth in most cases, so the optimal strategy is to plan your crafts around the timer and let them complete naturally. The crafting station also allows you to craft multiple items simultaneously, up to a limit of 3 items at a time, so the optimal strategy is to keep the crafting station constantly busy with ongoing crafts.
Crafting Materials: Common to Rare
Crafting materials for lower-tier gear are relatively easy to obtain. Uncommon upgrades require 10 uncommon essence and 100 cash. Rare upgrades require 10 rare essence and 500 cash. Uncommon essence drops from low-level raids at a rate of 20%, and rare essence drops from mid-level raids at a rate of 15%. The crafting fee is nominal, and the timer is short, so lower-tier crafts are essentially free upgrades that any player should pursue.
The crafting materials for epic upgrades are harder to obtain. Epic upgrades require 10 epic essence, 5 epic shards, and 2000 cash. Epic essence drops from high-level raids at a rate of 10%, and epic shards drop from tier 2-3 boss encounters at a rate of 8%. The crafting fee is significant but manageable for mid-game players, and the 24-hour timer is short enough that you can keep multiple epic crafts running simultaneously.
Crafting Materials: Legendary
Legendary upgrades require a substantial investment of materials and cash. A legendary upgrade requires 10 legendary essence, 5 legendary cores, 2 legendary stars, and 10,000 cash. Legendary essence drops from tier 3 boss encounters at a rate of 5%. Legendary cores drop from tier 3-4 boss encounters at a rate of 3%. Legendary stars drop from tier 4 boss encounters at a rate of 1%.
The crafting fee of 10,000 cash is a significant investment for mid-game players, and the 72-hour timer means that each legendary craft takes three days to complete. The optimal strategy is to start a legendary craft as soon as you have collected the materials, because the timer is long and you want to keep the crafting station constantly busy.
Where to Find Legendary Materials
The most reliable source of legendary materials is tier 3 boss encounters. The bosses drop all three legendary material types, and they drop them at a rate that makes grinding tier 3 bosses the most efficient way to collect materials. Tier 4 bosses have higher drop rates for legendary materials, but they are significantly harder to defeat, so the time investment per material drop is higher.
The gear shop also sells legendary materials during special events, but the prices are extremely high. The shop is only worth using if you need a specific material to complete a craft and you are willing to pay a premium. The optimal strategy is to rely on boss encounters for the majority of your legendary material needs.
Crafting Materials: Mythic
Mythic upgrades require an enormous investment of materials and cash. A mythic upgrade requires 10 mythic essence, 5 mythic cores, 2 mythic stars, and 50,000 cash. Mythic essence drops from tier 3-5 boss encounters at a rate of 3%. Mythic cores drop from tier 4-5 boss encounters at a rate of 2%. Mythic stars drop only from tier 5 boss encounters at a rate of 1%.
The crafting fee of 50,000 cash is a massive investment for even endgame players, and the 168-hour timer means that each mythic craft takes a full week to complete. The optimal strategy is to start a mythic craft as soon as you have collected the materials, because the timer is so long that you want to minimize any gaps between crafts.
The Tier 5 Boss Bottleneck
Mythic stars are the bottleneck in the crafting system, because they drop only from tier 5 boss encounters at a rate of 1%. Tier 5 bosses are the hardest content in Build a Base and Steal, and they require a full set of legendary gear to defeat. The result is a chicken-and-egg problem: you need legendary gear to defeat tier 5 bosses, but you need mythic stars to craft mythic gear, which would make defeating tier 5 bosses easier.
The solution is to grind tier 3-4 bosses until you have a full set of legendary gear, then attempt tier 5 bosses. Even with legendary gear, tier 5 bosses are challenging, and you should expect to fail several times before defeating your first tier 5 boss. The grind is difficult, but the reward is a guaranteed path to mythic gear.
Crafting Strategy: Which Items to Craft
Not every item is worth crafting. The crafting strategy should focus on items that have low drop rates and high utility. The mythic warhammer, for example, has a 1% drop rate from raids, but it is the strongest weapon in the game, so crafting it is correct. The mythic pickaxe, on the other hand, has a 1% drop rate from raids, but it is less essential than the warhammer, so rolling for it may be more efficient.
The optimal crafting strategy is to craft the mythic items that have the lowest drop rates and the highest utility, and to roll for the mythic items that have higher drop rates or lower utility. This strategy maximizes the return on your crafting materials and ensures that you are always investing in the most valuable items.
Crafting vs. Rolling
The choice between crafting and rolling depends on the drop rate of the item and your material stockpile. For items with drop rates below 1%, crafting is generally more efficient than rolling, because the crafting materials are more reliable than the random number generator. For items with drop rates above 1%, rolling may be more efficient, because the number of rolls required to obtain the item is lower than the number of boss encounters required to collect the crafting materials.
The general rule is: craft items with drop rates below 1%, roll for items with drop rates above 1%. This rule is not absolute, and individual circumstances may vary, but it is a good starting point for decision-making.
Crafting and the Gear Progression Path
Crafting is an integral part of the gear progression path. Early-game players should focus on crafting uncommon and rare upgrades, because the materials are easy to obtain and the crafts are cheap. Mid-game players should focus on crafting epic upgrades, because the materials are moderately difficult to obtain but the crafts are still affordable. Late-game players should focus on crafting legendary upgrades, because the materials are rare but the crafts are the most efficient way to obtain legendary gear.
Endgame players should focus on crafting mythic upgrades, because the materials are extremely rare but the crafts are the only guaranteed way to obtain mythic gear. The endgame crafting bottleneck is mythic stars, and the optimal strategy is to grind tier 5 bosses exclusively until you have enough stars to craft the mythic items you need.
Common Crafting Mistakes
The most common crafting mistake is crafting the wrong items. A player crafts a mythic rope first, even though the mythic rope has a 2% drop rate from raids, which is higher than the drop rate of the mythic warhammer. The fix is to prioritize crafting items with the lowest drop rates, because those are the items where crafting provides the most value.
The second most common mistake is ignoring the crafting timer. A player starts a mythic craft, and then starts another mythic craft immediately after, not realizing that the crafting station can only run 3 crafts simultaneously. The fix is to plan your crafts around the timer and ensure that you always have slots available for new crafts.
The third most common mistake is underestimating the material cost. A player starts a legendary craft without having collected all the materials, expecting to collect the remaining materials during the crafting timer. The fix is to collect all materials before starting the craft, because the materials are hard to obtain and you do not want the crafting station to sit idle while you grind for the missing materials.
The Crafting Endgame
The crafting endgame in Build a Base and Steal is the state where you have crafted a full set of mythic gear and upgraded it to level 10. At this point, the crafting system is effectively complete, and further progression comes from refining your raiding technique rather than from crafting new items. The crafting endgame is the ultimate achievement for dedicated players, and it represents months of grinding boss encounters and collecting materials.
Crafting is the guaranteed path to high-tier gear. It is slower than rolling for some items, but it eliminates variance and allows you to plan your progression with certainty. Master the crafting system, and you will never be at the mercy of the random number generator.
