Build a Base and Steal Target Selection - How to Find and Evaluate Raid Targets

Learn how to find and evaluate raid targets in Build a Base and Steal. Master target scoring, raid value calculation, and risk assessment to consistently pick profitable bases to attack.

The single biggest determinant of raid profitability in Build a Base and Steal is not your gear, your skill, or your raid team. It is your target selection. A skilled raider with mediocre gear who picks good targets will out-earn a skilled raider with the best gear who picks poor targets. This guide teaches you how to find, evaluate, and prioritize raid targets so that the majority of your raids are profitable, sustainable, and worth your time.

The Goal of Target Selection

Target selection is the process of identifying bases that meet specific criteria for profitability, accessibility, and risk. The goal is not to find the highest-value target in the server. The goal is to find the target with the best ratio of expected profit to expected cost. A 5,000-cash raid that costs you 1,000 in gear is more profitable than a 50,000-cash raid that costs you 45,000 in gear, even though the second has ten times the absolute profit.

The math of target selection is simple in principle and complex in practice. You estimate the value of the loot, subtract the cost of the gear, the cost of your time, and the probability-adjusted cost of failure, and compare the result to the alternative uses of your time. If the expected value is positive and higher than alternatives, you raid. If not, you do something else. The complexity comes from estimating the inputs accurately, which is where the techniques below help.

Building a Target Shortlist

A target shortlist is a list of 5 to 10 bases you have evaluated and ranked by expected profitability. You build the shortlist by walking the server, looking at bases, and applying a consistent evaluation framework. The shortlist is your working set of potential raids for the next few sessions.

Walking the Server

The simplest way to build a shortlist is to walk the server. Most public Build a Base and Steal servers allow you to see other players' bases from the outside. Walk the perimeter of the active area, look at every base, and note the ones that catch your attention. Pay particular attention to bases that show visible wealth, like a fully built wall layer, a complex trap layout, or a pet showcase with rare pets on display. Visible wealth is a strong signal that the base is worth raiding.

Walking the server has an additional benefit: it builds your intuition. The more bases you see, the faster you can evaluate them, and the more accurate your estimates become. Players who raid regularly develop a feel for which bases are vulnerable and which are not, and that feel is built by walking the server repeatedly over weeks and months.

Using the Public Listing

Many servers in Build a Base and Steal have a public base listing that shows every active base, with some information about each base's value, defense level, and recent activity. The public listing is the most efficient way to build a shortlist because you can see dozens of bases in a few minutes. The downside is that the listing shows only the most active bases, and the information is less detailed than what you can see by walking.

When using the public listing, sort by value descending and start at the top. The highest-value bases are the most attractive targets, but they also tend to be the most heavily defended. Do not assume that a high-value base is a good target; evaluate it on its merits.

Community Recommendations

The Build a Base and Steal community is a valuable source of target information. Experienced raiders share tips in Discord, on Reddit, and in-game chat about which bases are vulnerable, which players are inactive, and which bases are about to be abandoned. Community recommendations are not always reliable, because some recommendations are designed to lure you into traps. But the pattern of recommendations over time gives you a good sense of which targets the community considers viable.

Evaluating a Target's Value

The first input to your target evaluation is the expected value of the loot. This is the cash value of the pets, gear, and resources you expect to extract from the base. Estimating loot value accurately is a skill that improves with experience.

Visible Pet Count

The visible pet count is the number of pets you can see from outside the base. A base with ten visible pets is more attractive than a base with three visible pets, all else being equal. The visible pet count is a rough signal, because the player may have many more pets stored out of sight, but it is a starting point for your evaluation.

The quality of the visible pets matters as much as the count. A base with three legendary pets visible is more valuable than a base with ten common pets, even though the count is lower. When you see a legendary pet in a base, the entire base becomes a much higher-value target. Legendary pets are worth roughly 10x to 20x a common pet, so the expected loot value of a base with a single legendary visible pet is dramatically higher.

Showcase Areas

Many players keep their most valuable pets in showcase areas, which are designed to be visible from outside the base. The showcase is a gift to the raider: it shows you exactly what is in the base. A base with a visible showcase of rare and legendary pets is a much more reliable target than a base with an empty showcase, because the empty showcase might mean the player has nothing valuable, but it might also mean the valuables are hidden inside.

A base with a substantial showcase is also a higher-status target, which means the player has invested significantly in the base and is likely to defend it actively. This is a double-edged sword: the loot is better, but the response will be faster. The expected value of a heavily showcased base is higher, but the expected cost is also higher.

Inferred Hidden Value

The visible pets are not the entire story. Most players hide their most valuable pets in the vault or in a hidden section, which means the actual loot value is almost always higher than what you can see. A reasonable rule of thumb is to assume that the actual loot value is 2x to 5x the visible loot value, depending on the size of the base and the apparent wealth of the player.

Larger bases tend to have more hidden value, because the player can afford to maintain a vault and a hidden section. Smaller bases tend to have less hidden value, because the player cannot afford extensive hidden storage. Adjust your estimate based on the size and apparent resources of the target.

Evaluating a Target's Defenses

The second input is the expected cost of breaching the base's defenses. The defenses include walls, traps, surveillance, and active defenders. Estimating defense cost accurately is the difference between a profitable raid and a costly loss.

Wall Quality and Layers

Walk the perimeter of the base and observe the walls. Count the layers, note the material (which is usually identifiable by texture and color), and look for any obvious weak points. A base with one layer of stone walls is significantly cheaper to breach than a base with three layers, the first of which is reinforced alloy. Estimate the time and gear cost based on your observations.

Wall layers are the most visible defensive element, but they are also the most common to overstate. A base with three wall layers is not three times as defended as a base with one layer, because the breaching cost is not linear. The second layer adds less time than the first, because the raider is already inside and committed. The third layer adds even less, because the raider is close to the loot and willing to spend more to finish. A base with three layers is roughly twice as defended as a base with one layer, not three times as defended.

Trap Visibility

Look for visible trap indicators. Some traps are completely hidden, but many leave subtle visual cues: a slight discoloration on the floor, a small device attached to a wall, a faint glow in a dark corridor. Even if you cannot see the trap itself, the indicators tell you that a trap is present. Count the indicators and estimate the trap density.

A base with many trap indicators is more defended than a base with few indicators, but the relationship is not linear. A base with five trap indicators may have five traps or may have fifteen, because some players place multiple traps in the same location. The indicators are a lower bound, not an exact count.

Active Defenders

Some targets have active defenders who respond to raids in real time. The presence of an active defender significantly increases the cost of a raid, because the defender can repair walls, replenish traps, and even relocate valuables mid-raid. The presence of a defender is the single most important defensive signal, because no amount of walls and traps can fully compensate for an active defender.

You can detect an active defender by checking the player's recent activity. If the player has been online in the last few minutes, they are likely to respond if you raid. If the player has not been online for hours, they are unlikely to respond, and the raid is much less risky. Some experienced players wait for inactive periods to raid high-value targets, which is why activity tracking is so important.

The Target Score

Once you have evaluated the value and the defenses, calculate a target score. The score is a single number that represents the overall attractiveness of the target. The simplest scoring formula is:

Score = Expected Loot Value / Expected Breach Cost

A target with a high score is more attractive than a target with a low score. Use the score to rank your shortlist and raid the highest-scoring targets first. The formula is intentionally simple, because a complex formula introduces more opportunities for estimation error. The simpler the formula, the more reliable the score.

Adjustments to the Score

The basic score does not account for some important factors. Adjust the score based on the following:

  • Recent raid history: If the base has been raided successfully in the last 24 hours, the loot is probably lower than estimated. Reduce the value by 30% to 50%.

  • Time of day: Bases owned by players in different time zones are more vulnerable when their owners are asleep. Increase the value slightly for inactive players.

  • Defense activity: If the player has been actively upgrading defenses, the breach cost is higher than estimated. Reduce the score by 10% to 20%.

  • Your gear: If your gear is significantly better or worse than the typical gear for your progression level, adjust the breach cost accordingly. Better gear reduces the cost; worse gear increases it.

Risk Management

Target selection is inherently risky, because the estimates are never perfect. The actual loot and the actual breach cost can deviate significantly from the estimates. Risk management is the discipline of accepting some uncertainty while preventing catastrophic losses.

The Stop-Loss Rule

Set a stop-loss rule before you start raiding. The stop-loss is the maximum amount of cash you are willing to lose on a single raid. If the raid is going badly and the cost is approaching the stop-loss, retreat and accept the loss. The most common stop-loss is 50% of the gear value, meaning you retreat when the gear cost reaches half the estimated loot value. This rule prevents a single bad raid from wiping out your gear budget.

The Diversification Rule

Do not raid the same target repeatedly in a short period. A repeated raid is a high-risk activity, because the defender has had time to repair, reinforce, and reposition their defenses. Spread your raids across multiple targets, and revisit a target only after a meaningful cooling period, typically 24 to 48 hours.

The Skim Rule

A skim is a raid that extracts the most accessible loot and retreats, without trying to reach the vault. Skims are lower-reward but lower-risk raids. They are appropriate when you want to reduce your activity without committing to a full raid, or when the target's defenses are uncertain. The skim rule says that if you are not confident about a full raid, take a skim instead. Skims are profitable more often than full raids, even though the absolute profit is lower.

Common Selection Mistakes

The most common target selection mistakes are predictable. Avoiding them is the easiest way to improve your raid profitability.

The High-Value Trap

The high-value trap is a base that displays a single extremely valuable pet, like a mythical, but is otherwise heavily defended. The base is designed to attract exactly the kind of raider who targets high-value bases. The mythical is real, but the defenses are designed to make the raid cost more than the mythical is worth. The high-value trap is more common in late game, where experienced players set up decoy bases specifically to catch ambitious raiders. The way to avoid the high-value trap is to evaluate the entire base, not just the showcase.

The Abandoned Base Illusion

An abandoned base looks like a profitable target because it appears undefended, but it is often a trap set by the owner, who logs in only when a raid begins. The abandoned base illusion is a base with no recent activity that suddenly has an active defender the moment a raid starts. The way to avoid the abandoned base illusion is to check the player's recent activity thoroughly, not just their current status.

The Over-Confident Target

The over-confident target is a base that is heavily defended but whose owner is so confident in their defenses that they have left obvious vulnerabilities, like a back entrance or a weak wall section. The over-confident target is more common than expected, because many players design their base from the inside out and never test it from the outside. A base that looks like a fortress may have an obvious weakness that the owner has not noticed. Look for these weaknesses when evaluating a target, but be aware that some are deliberate traps.

Conclusion: Pick the Right Targets, Not the Most Targets

The most successful raiders in Build a Base and Steal are not the ones who raid the most often. They are the ones who raid the most selectively. A shortlist of well-evaluated targets, scored on the ratio of expected loot to expected breach cost, will produce more profit than a long list of casually selected targets. Build the shortlist, evaluate each target on the same framework, adjust for risk, and raid the highest-scoring targets. The math of target selection is simple, and the discipline of applying it consistently is what separates profitable raiders from unprofitable ones.

FAQ

What should I do if the strategy stops working after a patch?

Watch the patch notes for any changes to target selection mechanics. Once you have this principle down, you can stop reading specific guides and start generating your own strategies, because the principle will tell you which actions make sense for your specific situation.

Where can I find more detailed information about this topic?

The community wiki, Discord, and dev blog are the most reliable sources for target selection information. Once you have this principle down, you can stop reading specific guides and start generating your own strategies, because the principle will tell you which actions make sense for your specific situation.

How does target selection interact with the trading economy?

Trading and target selection are tightly coupled. The pets you acquire through target selection can be traded. The reason experienced players progress so much faster is that they have internalized principles like this one, and they can apply them to any new system or patch without having to relearn the fundamentals.

What is the best time of day to focus on target selection?

Timing depends on your region and which events are running. The reason experienced players progress so much faster is that they have internalized principles like this one, and they can apply them to any new system or patch without having to relearn the fundamentals.

How much cash should I budget for target selection per session?

Allocate 20-30 percent of daily income to target selection. This is the kind of insight that does not appear in patch notes but determines who ends up on the monthly leaderboard, and who does not.
