Rise of Kingdoms Castle Guide: Introduction to the Castle in Rise of Kingdoms
Rise of Kingdoms Castle Guide: The Castle is one of the most crucial buildings in Rise of Kingdoms, playing a major role in military strength and strategic growth. Unlike most other structures, upgrading the Castle requires a special resource—the Book of Covenant—making it one of the more challenging buildings to advance. However, the benefits of upgrading it are well worth the effort, as a higher-level Castle allows for stronger armies, more effective rallies, and access to the game’s most powerful troops. The Rise of Kingdoms Castle Guide is here to help players navigate the importance of this structure and understand how it impacts their progression.
One of the key functions of the Castle is its role in rallies. A higher Castle level increases the number of troops a player can lead in a rally, making it an essential structure for those who want to participate in large-scale battles. Whether attacking Barbarian Forts or leading alliance-wide assaults against enemy cities, a well-upgraded Castle gives governors a significant advantage. The Rise of Kingdoms Castle Guide highlights how investing in the Castle directly enhances a player’s effectiveness on the battlefield.
Beyond its role in rally leadership, the Castle is also a major prerequisite for unlocking Tier 5 troops, the most powerful units in the game. Without reaching Castle Level 25, players will not be able to upgrade their Academy to the same level, which is necessary for researching Tier 5 technologies. This means that advancing the Castle is not just about rally size—it’s also a crucial step toward achieving the highest levels of military power. The Rise of Kingdoms Castle Guide stresses that governors aiming for endgame dominance must prioritize Castle upgrades to stay competitive.
Additionally, the Castle plays an indirect role in city infrastructure, as a Level 25 Castle is a prerequisite for upgrading the Hospital to its maximum level. A stronger Hospital allows for greater troop recovery after battles, making it easier to sustain prolonged wars. Since healing troops is far more resource-efficient than training new ones, a well-upgraded Castle ultimately contributes to maintaining a strong, battle-ready army. The Rise of Kingdoms Castle Guide recommends that players keep this in mind when planning their city’s long-term development.
While upgrading the Castle is a difficult and resource-intensive process, the benefits it provides make it a top priority for serious players. Whether it’s increasing rally capacity, unlocking Tier 5 troops, or strengthening the city’s defenses, the Castle stands as a cornerstone of success in Rise of Kingdoms. By following the Rise of Kingdoms Castle Guide, players can make informed decisions on how to efficiently gather Books of Covenant, manage their resources, and optimize their progression toward a fully upgraded Castle.
Rise of Kingdoms Castle Guide: The Importance of Castle Upgrades in Rise of Kingdoms

Rise of Kingdoms Castle Guide: The Castle is one of the most essential buildings in Rise of Kingdoms, directly impacting a player’s ability to lead armies, research advanced technologies, and command larger forces in battle. While many buildings contribute to city development and military strength, the Castle stands out as a crucial structure that determines how far a governor can progress. The Rise of Kingdoms Castle Guide emphasizes why upgrading the Castle should be a top priority for any player looking to dominate the battlefield.
One of the biggest reasons to invest in Castle upgrades is that it is a requirement for upgrading the Academy to Level 25. The Academy is responsible for researching new technologies, including the all-important Tier 5 troops. Without a fully upgraded Castle, players will find themselves stuck at a lower Academy level, preventing them from unlocking the most powerful units in the game. The Rise of Kingdoms Castle Guide strongly encourages players to start working on their Castle upgrades early to avoid delays in their progression.
Beyond its role in research, the Castle is also essential for training and commanding Tier 5 troops. Tier 5 units are the strongest in the game, providing superior stats and combat effectiveness compared to lower-tier troops. However, reaching Tier 5 is a long and challenging journey, and upgrading the Castle to Level 25 is a necessary step along the way. Without this upgrade, a player’s military potential remains limited, making it difficult to compete against stronger opponents. The Rise of Kingdoms Castle Guide highlights that for players aiming to become top-tier warriors, prioritizing Castle upgrades is non-negotiable.
Another critical benefit of upgrading the Castle is the ability to lead larger rallies. Rallies are crucial for attacking Barbarian Forts, challenging enemy alliances, and securing key objectives in Kingdom versus Kingdom (KvK) battles. A higher-level Castle increases the number of troops that can participate in a rally, making attacks more effective and increasing the chances of victory. The Rise of Kingdoms Castle Guide advises that players who want to be effective rally leaders must continually upgrade their Castle to maximize their impact on the battlefield.
While Castle upgrades may not seem like an immediate priority in the early stages of the game, they become increasingly important as players approach Tier 5 troops and large-scale warfare. Many governors find themselves rushing to upgrade their Castle later in the game, realizing too late how vital it is for progression. The Rise of Kingdoms Castle Guide recommends that players start gathering Books of Covenant as early as possible to ensure a smooth and steady upgrade path.
Ultimately, the Castle serves as a gateway to elite military power and strategic dominance. Whether it’s unlocking Tier 5 troops, leading larger rallies, or advancing research capabilities, upgrading this structure is a fundamental part of long-term success in Rise of Kingdoms. By following the Rise of Kingdoms Castle Guide, players can plan their upgrades wisely, ensuring they stay ahead of the competition and continue growing their kingdom without unnecessary setbacks.
Rise of Kingdoms Castle Guide: Castle Upgrade Requirements in Rise of Kingdoms

Rise of Kingdoms Castle Guide: Upgrading the Castle is one of the most significant milestones in Rise of Kingdoms, and reaching Level 25 is essential for unlocking the full potential of your city. However, the process is far from easy. Unlike other structures that primarily require resources and building time, the Castle demands a unique and often difficult-to-obtain currency—the Book of Covenant. The Rise of Kingdoms Castle Guide emphasizes how crucial it is to plan for these requirements to avoid unnecessary delays in progression.
One of the most important prerequisites for upgrading the Castle is ensuring that all other buildings in the city are also at Level 25. This can be a major challenge, as certain structures, such as the Academy and Hospital, require significant resources and time to upgrade. Players must prioritize leveling up their infrastructure efficiently to avoid bottlenecks when they are finally ready to advance their Castle. The Rise of Kingdoms Castle Guide advises players to steadily upgrade their buildings alongside their Castle to maintain a balanced city development.
The biggest challenge of upgrading the Castle is obtaining Books of Covenant, which are essential for every level increase. Unlike traditional resources like food, wood, stone, and gold, these books cannot be farmed or easily gathered. They are primarily obtained through defeating Barbarian Forts, purchasing them from the VIP shop, or spending gems in the store. Due to the sheer number required—especially at higher Castle levels—players will often find themselves spending a significant amount of action points and gems to collect enough Books of Covenant. The Rise of Kingdoms Castle Guide strongly recommends farming these books early and participating in rally attacks on Barbarian Forts to accumulate them over time.
While the direct resource cost for upgrading the Castle is relatively low compared to other major buildings, the real expense comes from gem usage and action point consumption. Players who do not actively participate in rallies or who choose to buy Books of Covenant from the shop will find themselves spending thousands of gems to progress. This makes the Castle one of the most expensive buildings to upgrade in the entire game. The Rise of Kingdoms Castle Guide suggests that free-to-play players focus on grinding Barbarian Forts daily, while spenders may find it more efficient to invest gems strategically during special events or VIP shop refreshments.
Given these challenges, upgrading the Castle is not just about reaching Level 25—it’s about careful planning and efficient resource management. Players who rush their upgrades without securing enough Books of Covenant will find themselves stuck, delaying their progress toward Tier 5 troops and larger rally capacities. The Rise of Kingdoms Castle Guide stresses the importance of patience and strategy, ensuring that every governor can progress smoothly without unnecessary setbacks.
Rise of Kingdoms Castle Guide: The Book of Covenant in Rise of Kingdoms

Rise of Kingdoms Castle Guide: The Book of Covenant is one of the most crucial yet challenging resources to acquire in Rise of Kingdoms. Unlike other upgraded materials, this item is exclusively required for advancing the Castle, making it a key component in unlocking Tier 5 troops and expanding rally capacities. The Rise of Kingdoms Castle Guide highlights the importance of planning ahead when collecting Books of Covenant, as the sheer number needed increases dramatically at higher levels.
What makes the Book of Covenant so difficult to obtain is that it is not rewarded through regular in-game events. While many other resources and materials can be earned through farming, quests, or special events, this book requires specific strategies to collect efficiently. The Rise of Kingdoms Castle Guide strongly advises players to start gathering Books of Covenant as early as possible to avoid delays in their Castle progression.
One of the primary ways to obtain Books of Covenant is by defeating Barbarian Forts through alliance rallies. Each successful rally grants a chance to earn Books of Covenant, but the drop rates can vary. Since upgrading the Castle requires thousands of books, players must consistently participate in fort rallies, which also means investing a significant amount of action points. The Rise of Kingdoms Castle Guide suggests teaming up with active alliances that frequently run rallies to maximize book collection over time.
Another way to obtain Books of Covenant is by purchasing them with gems from the shop. However, this method can become incredibly expensive, especially in later upgrades. The cost increases significantly with each purchase, making it a costly but effective option for players who want to speed up their Castle progression. The Rise of Kingdoms Castle Guide recommends free-to-play players focus on grinding forts, while spenders may consider gem purchases strategically, such as during VIP shop resets or special bundle offers.
The number of Books of Covenant required for Castle upgrades increases exponentially at each level. In total, 20,095 Books of Covenant are needed to upgrade the Castle from Level 1 to Level 25. The final jump from Level 24 to Level 25 alone requires a staggering 5,000 books, making it the most challenging level to complete. This massive requirement often causes delays for players aiming to reach Tier 5 troops, reinforcing the need for early preparation and consistent fort rally participation.
Given how essential the Castle is for advanced gameplay, securing enough Books of Covenant should be a long-term priority. The Rise of Kingdoms Castle Guide encourages players to be patient and persistent, as rushing through with gems can be costly, while slow and steady fort farming remains the most sustainable method. Those who stay committed to collecting books will eventually unlock the full potential of their Castle, gaining access to stronger troops, larger rallies, and a more powerful kingdom overall.
Rise of Kingdoms Castle Guide: How to Obtain the Book of Covenant in Rise of Kingdoms

Rise of Kingdoms Castle Guide: Acquiring the Book of Covenant is one of the most challenging aspects of upgrading the Castle in Rise of Kingdoms. Since this item is essential for progressing to higher Castle levels, players must actively seek efficient ways to collect it. The Rise of Kingdoms Castle Guide provides valuable insights on the best methods to gather Books of Covenant, whether through free-to-play strategies or paid options.
For free-to-play (F2P) players, the most effective method is defeating Barbarian Forts. Each time a Barbarian Fort is destroyed, there is a chance to earn Books of Covenant. The number of books received depends on the total damage dealt, which means sending more troops and participating in multiple alliance rallies increases your potential rewards. Since attacking Barbarian Forts requires action points, it is important to manage AP wisely and prioritize rallies whenever possible. The Rise of Kingdoms Castle Guide recommends teaming up with an active alliance that frequently targets forts to maximize book collection.
Another free-to-play method is earning Books of Covenant through Alliance Gift Chests. When alliance members purchase specific bundles, these chests may contain Books of Covenant. Additionally, the Treasure of Crystal is another possible source found within these gifts. While this method relies on the spending activity of others, being in a high-spending alliance can provide a steady influx of Books of Covenant over time.
Special in-game events occasionally offer Books of Covenant as rewards. While these events are not always predictable, keeping an eye on seasonal or limited-time events can provide opportunities to earn books without spending gems. The Rise of Kingdoms Castle Guide advises players to actively participate in events whenever Books of Covenant are listed as rewards, as these opportunities can significantly reduce the grind.
For pay-to-win (P2W) players, the fastest way to obtain Books of Covenant is through VIP chests. As players progress through higher VIP levels, they unlock significant amounts of Books of Covenant as part of their VIP rewards. For example, VIP Level 2 grants 100 books, VIP Level 4 grants 300, and VIP Level 10 provides 1,000 books, with the highest rewards coming from VIP Levels 13 and 14, which each provide 2,000 Books of Covenant. In total, 5,900 books can be obtained from VIP chests alone, making this an efficient route for players willing to invest in VIP progression.
Another P2W option is buying Books of Covenant directly with gems. The books are available for 10 gems each, meaning upgrading a Castle from Level 1 to Level 25 purely through gem purchases would cost an astonishing 200,950 gems. While this is the most direct way to obtain the required books, it is also the most expensive, making it a last resort for players who are looking for a quick upgrade. The Rise of Kingdoms Castle Guide recommends spending gems strategically, such as during Mysterious Merchant discounts or in conjunction with VIP purchases to maximize efficiency.
Regardless of playstyle, collecting Books of Covenant requires a consistent, long-term effort. Free-to-play players should focus on fort rallies and alliance activity, while spenders can leverage VIP chests and gem purchases to speed up their Castle progression. The Rise of Kingdoms Castle Guide emphasizes patience and persistence, as upgrading the Castle is a crucial milestone that unlocks powerful troops, larger rallies, and overall kingdom growth.
Rise of Kingdoms Castle Guide: Recommended Strategies for Castle Upgrades in Rise of Kingdoms

Rise of Kingdoms Castle Guide: Upgrading your Castle efficiently is one of the most important goals in Rise of Kingdoms. Since the Castle is required for rallying, training Tier 5 troops, and unlocking higher-level research, having a solid strategy can make a huge difference in progression. The Rise of Kingdoms Castle Guide provides key strategies that will help players—whether free-to-play or spenders—reach their Castle upgrade goals faster while making the best use of resources.
One of the most effective long-term strategies is to prioritize reaching VIP Level 10 as early as possible. VIP Level 10 provides a free Legendary Commander Sculpture every day, which can be used to strengthen powerful commanders for battles and rallies. In addition, VIP chests at higher levels contain Books of Covenant, making VIP progression a key advantage. Players should use their free daily VIP points and spend extra gems on VIP upgrades rather than rushing Castle levels without a plan. The Rise of Kingdoms Castle Guide recommends focusing on VIP advancement before investing heavily in Books of Covenant through gem purchases.
For those planning to spend gems on Books of Covenant, it is best to maximize the “More than Gems” event. This event provides additional rewards when spending gems, making it the most efficient time to purchase Books of Covenant. Instead of buying books at random times, saving up gems and spending them during this event will significantly increase overall rewards. By timing purchases strategically, players can accumulate Books of Covenant without feeling like they are wasting gems. The Rise of Kingdoms Castle Guide suggests checking event schedules regularly to prepare for this opportunity.
Another crucial tip is to save speed-ups until the Castle and Academy reach Level 25. Many players make the mistake of using speed-ups on research too early, which can lead to maxed-out technology while still having lower-level buildings. Since Tier 5 troops require both a Level 25 Castle and Academy, it is better to prioritize these upgrades first. If speed-ups are used on research before these buildings are maxed, players may find themselves stuck, unable to progress further without an unnecessary waiting period. The Rise of Kingdoms Castle Guide advises using speed-ups wisely and focusing on building upgrades before rushing research.
Farming Barbarian Forts is one of the best free-to-play methods for acquiring Books of Covenant, but it requires a well-planned approach. Using peacekeeper commanders such as Lohar, Aethelflaed, or Boudica reduces action point (AP) costs while increasing rewards. Players should also create farm accounts to maximize the number of forts rallies they can participate in. Lower-level forts may drop fewer books per rally but consistently attacking them with multiple accounts ensures a steady collection over time. The Rise of Kingdoms Castle Guide strongly recommends joining an active alliance that regularly rallies forts, as this will significantly speed up the process of collecting Books of Covenant.
By following these strategies, players can optimize their Castle progression, ensuring they reach higher rally capacities, unlock Tier 5 troops, and strengthen their overall kingdom without unnecessary delays. The Rise of Kingdoms Castle Guide emphasizes the importance of long-term planning, efficient resource management, and strategic spending to make the Castle upgrade journey as smooth as possible.
Rise of Kingdoms Castle Guide: Castle Upgrade Costs in Rise of Kingdoms

Rise of Kingdoms Castle Guide: Upgrading your Castle in Rise of Kingdoms is one of the most challenging tasks due to the high demand for Books of Covenant and the significant investment required in gems, action points, and time. Understanding these costs is essential for efficient progression. The Rise of Kingdoms Castle Guide provides a detailed breakdown of what it takes to upgrade the Castle from Level 1 to Level 25, helping players prepare for the long journey ahead.
The total number of Books of Covenant required to upgrade the Castle from Level 1 to Level 25 is 20,095. Since these books are not naturally generated through regular gameplay, acquiring them is a significant challenge. Players must either farm Barbarian Forts or spend gems to obtain them. The Rise of Kingdoms Castle Guide highlights that upgrading from Level 24 to Level 25 alone requires 5,000 Books of Covenant, which translates to 50,000 gems if purchased directly. This final level is the most expensive, making strategic planning even more important.
For free-to-play (F2P) players, farming Barbarian Forts is the primary method of collecting Books of Covenant. However, this method requires an extensive amount of action points (AP). To put it into perspective, obtaining 20,095 Books of Covenant through forts would require destroying approximately 4,017 Barbarian Forts, consuming an estimated 602,610 action points in total. Since action points regenerate slowly, this farming method takes considerable time, and players must carefully manage their AP consumption. The Rise of Kingdoms Castle Guide advises joining a highly active alliance to maximize rally participation, making the process more efficient.
For pay-to-win (P2W) players, the process is significantly faster but comes at a high gem cost. Since Books of Covenant can be purchased for 10 gems each, upgrading from Level 1 to Level 25 would cost a total of 200,950 gems. While this is a steep price, spending gems strategically during the “More than Gems” event can help mitigate some of the cost by providing additional rewards. The Rise of Kingdoms Castle Guide recommends waiting for these special events rather than purchasing books at random times.
Apart from the Books of Covenant and gems, upgrading the Castle also requires upgrading the Alliance Center, as the Castle level is tied to the Alliance Center’s level. This means additional time and resources must be invested in leveling up support structures before reaching Castle Level 25. Since the Alliance Center affects the number of reinforcements a player can receive, keeping it upgraded is crucial for both defense and fort rallies.
The journey to a Level 25 Castle is long and resource-intensive, requiring careful planning, patience, and efficient resource management. Whether a player follows an F2P strategy of farming forts or a P2W approach using gems, understanding the full scope of the costs involved is essential. The Rise of Kingdoms Castle Guide provides this detailed breakdown to help players make the best choices based on their available resources and gameplay style.
