Event raids in Build a Base and Steal are special raid opportunities that appear during limited-time events, and they are the most lucrative raiding activity in the game. The event raids typically offer boosted loot, exclusive rewards, and special mechanics that are not available during regular play. The catch is that the events have short windows, and the boosted rewards attract more raiders, which means more competition. This guide covers the event raid mechanics, the typical rewards, the strategy for maximizing event raid income, and the long-term role of event raids in your raiding career.
How Event Raids Work
Event raids are activated during limited-time events, which are announced through the in-game event panel and the official social media. The event usually runs for 1 to 2 weeks, and during that window, the raid mechanics are modified to provide boosted rewards.
The most common modification is the loot multiplier, which increases the cash and pet value of the extracted loot. The multiplier is usually 2x to 5x the normal value, and it applies to all raids performed during the event window. The multiplier is the main draw of the event raids, because it directly increases the profitability of every raid.
The second common modification is the exclusive pet, which is a pet that can only be obtained during the event. The exclusive pet is usually a legendary or mythical, and it is one of the most sought-after items in the event. The exclusive pet can be extracted from bases during raids, or it can be earned through event-specific activities.
The third common modification is the bonus objective, which is a specific goal that grants extra rewards when completed. The bonus objective might be "raid 20 bases during the event for a free legendary roll" or "extract 5 mythical pets during the event for an exclusive avatar item." The bonus objectives incentivize specific activities and reward the most active raiders.
The Event Calendar
Build a Base and Steal runs event raids on a roughly monthly schedule, with major events during the holiday seasons and minor events during the off-season. The event calendar is not officially published, but the historical pattern is predictable.
January typically features a New Year raid event with 2x loot for one week. February features a smaller Valentine's event with exclusive pet rewards. March features the anniversary event with the most generous raid rewards of the year. April through August feature smaller monthly events, usually with 1.5x to 2x loot. September features a back-to-school event. October features the Halloween event with spooky-themed exclusive pets. November features the Black Friday event with cash-shop discounts. December features the winter event with the most diverse raid rewards.
The major events (anniversary, Halloween, winter) are the most lucrative, and they are worth planning around. The minor events are still profitable, but the rewards are smaller, and the time investment may not be worth it for casual players.
The Event Raid Strategy
The optimal strategy for event raids is to front-load your activity at the start of the event. The first 24 to 48 hours of an event are the most lucrative, because the event-exclusive items are most abundant in player bases (players have not yet extracted them), and the raid competition is lower (some players are still learning about the event).
The second strategy is to focus on the bonus objectives. The bonus objectives provide a clear target for your raiding activity, and they reward the most active raiders with exclusive items that are not available through any other means. The bonus objectives are usually achievable within a few days of focused raiding, and they are worth prioritizing over regular raid targets.
The third strategy is to save your raid energy for the event window. The raid energy regenerates over time, and saving it means you have a full pool of energy to use during the event. The energy that is used during the event produces event-boosted rewards, which are worth 2x to 5x the normal value. The energy that is used outside the event produces normal rewards, which are worth much less.
The Event Preparation
Event preparation is the practice of setting up your account for the event before it starts. The preparation includes stocking up on gear, accumulating raid energy, and identifying the targets you want to hit.
Gear preparation means having a full loadout of weapons, tools, support items, and consumables ready for the event. The gear should be appropriate for the types of bases you will be raiding, and you should have backup gear in case your primary gear is depleted. The gear can be purchased in advance of the event, when the prices are usually lower.
Raid energy preparation means saving your raid energy in the days before the event, so you have a full pool to use during the event. The raid energy can be banked up to a certain cap, and the cap is usually enough for 2 to 3 days of event raiding. The energy is most efficiently used in concentrated bursts during the event, not in continuous low-intensity raids.
Target preparation means identifying the bases you want to raid during the event, based on your knowledge of the player base and the event objectives. The targets can be identified by walking the server, by checking the public listing, or by asking for tips in the community Discord. The preparation is not strictly necessary, but it saves time during the event itself.
The Event Raid Loot Priority
During an event raid, the loot priority is different from a normal raid. The event-exclusive pets are the highest priority, because they are only available during the event and they can be sold for a substantial profit in the trading hub. The legendary and mythical pets are the second priority, because the event multiplier increases their value. The cash is the third priority, because cash is always useful but it is not event-specific.
The loot priority should be communicated to your team if you are doing a coordinated raid. The team should agree on the priority before the raid, and the team members should focus on their assigned priorities during the raid. The agreement prevents conflicts during the loot splitting, and it ensures that the highest-value items are extracted first.
The loot priority should also inform your target selection. Bases that are likely to contain event-exclusive pets should be raided first, because the pets are the most valuable loot. Bases that are likely to contain only regular pets should be raided later, when the event-exclusive pets have already been extracted from the more attractive targets.
The Event Raid Risks
Event raids are not without risks. The most significant risk is the increased competition, which means more raiders are active and the targets are more likely to be heavily defended. The competition can make it harder to find undefended targets, and the increased defender presence increases the chance of counter-raids.
The second risk is the gear depletion. The increased raid frequency consumes gear at a higher rate, and players who do not have sufficient backup gear may find themselves unable to raid for the last few days of the event. The depletion is most pronounced for solo raiders, who do not have a team to share the gear cost.
The third risk is the burnout. Event raids are intense, and the concentration of activity in a short window can lead to fatigue and frustration. Players who push too hard during an event often find themselves taking a break after the event, which slows their overall progression. The fix is to pace the event activity, not to push for maximum raids every day.
The Post-Event Strategy
The post-event period is the time after the event ends, and it is when the event-exclusive pets reach their peak trading value. The peak value is because the supply of the pets is now fixed (no more can be obtained from the event), and the demand is high (players who missed the event want to buy the pets).
The optimal post-event strategy is to sell the event-exclusive pets during the peak value window, which is usually 1 to 2 weeks after the event ends. The price is highest at the start of the post-event period, and it gradually decreases as more pets enter the market and the demand normalizes.
The post-event period is also a good time to evaluate your event performance. The review should answer: Did I achieve the bonus objectives? Did my raid income exceed the gear cost? Did I extract the event-exclusive pets? The evaluation informs your strategy for the next event, and the lessons learned compound over multiple events.
Long-Term Event Planning
The long-term event planning is the practice of structuring your account around the event calendar. The planning includes saving raid energy for major events, accumulating gear for event windows, and targeting your pet collection toward the event-exclusive pets.
The long-term planner also keeps a calendar of past and expected events, with notes on the rewards and the strategies that worked. The calendar is the source of the data that informs future event preparation, and the planner who maintains the calendar has a significant advantage over the player who reacts to each event as it appears.
The long-term planning is most valuable for players who want to maximize their event income. The events are the most lucrative raiding opportunities in the game, and the player who is prepared for every event extracts significantly more value from the events than the player who is not prepared. The preparation is the difference between raiding as a hobby and raiding as a serious income source.

FAQ
How much cash should I budget for event raids per session?
Allocate 20-30 percent of daily income to event raids. Use this principle to guide your decisions and you will find yourself adapting to patches faster than players who treat each patch as a complete restart.
What is the most important event raids concept for new players?
The most important concept is that every action in event raids has opportunity cost. 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.
How long does it take to see results from this strategy?
Expect a 7-14 day window before you see noticeable improvement in event raids outcomes. Internalizing this principle is what separates players who plateau from players who keep climbing, and the difference is visible in the leaderboard positions after just a few weeks.
Does this strategy work for both solo players and teams?
The approach works for both solo and team play. You will see this principle echoed in every serious event raids discussion on Discord, because the most active players have all arrived at the same conclusion through their own experience.
What should I do if the strategy stops working after a patch?
Check the patch notes for any system changes that affect event raids. Internalizing this principle is what separates players who plateau from players who keep climbing, and the difference is visible in the leaderboard positions after just a few weeks.
