Introduction to Monster Fusion
Monster Fusion in Summoners War: Sky Arena is a fundamental gameplay mechanic that enables players to combine specific monsters to create a new, more powerful unit. Summoners War Monster Fusion provides a structured path to acquiring strong monsters without relying solely on luck-based summoning methods. By strategically collecting and leveling fusion material monsters, players can secure key units that are critical for game progression.
Engaging in monster fusion is essential for several reasons. First, it allows you to obtain important monsters needed for early to mid-game advancement. These fusion monsters often fill core roles in your teams, providing stability and strength across various content types. One of the most notable fusion monsters is Veromos (Dark Ifrit), a unit that plays a central role in early Giants B10 and Dragons B10 teams. Veromos offers consistent debuff removal and deals sustained damage, making him a cornerstone for early PvE strategy.
Another high-value fusion monster is Sigmarus (Water Phoenix). Sigmarus excels in Giants B10, Dragons B10, and the Tower of Ascension (ToA) due to his powerful AoE damage and HP-scaling skills. He is often one of the first major damage dealers players aim to fuse, offering strong utility across a wide range of content.
Beyond Veromos and Sigmarus, other fusion monsters cater to specific roles and scenarios in the game. Some are ideal for dungeon progression, while others shine in boss battles and other PvE environments. Building these monsters through fusion not only improves your team strength but also ensures a reliable way to acquire monsters that are otherwise difficult to summon.
The fusion process is carried out at the Fusion Hexagram, a dedicated building that becomes available on your island once your account reaches level 17. This building is the centerpiece of the fusion system, allowing you to combine specific monsters to create new, powerful units that are often essential for progressing through various stages of the game.
While the Fusion Hexagram itself unlocks at level 17, one of the most effective strategies for efficient fusion is to begin collecting the required monsters well in advance. By farming monsters from scenario stages, summoning from scrolls, and gathering pieces from Secret Dungeons early on, you can prepare all the necessary components so that you’re ready to fuse as soon as the building becomes available. This proactive approach not only saves time but also prevents unnecessary delays in your progression.
Key Fusion Monsters and Their Materials
Monster Fusion in Summoners War: Sky Arena is a structured system where specific sets of monsters are combined to summon powerful units. These fusion monsters play critical roles in progressing through early, mid, and even late-game content. Each fusion requires exact material monsters, which must be fully awakened and leveled to their maximum level at their respective star grades.
Veromos (Dark Ifrit)
Veromos is one of the most impactful early-game fusion monsters. His passive skill, “Conversion of Magic,” cleanses harmful effects from all allies at the start of each turn, making him invaluable in Giants B10 (GB10), Dragons B10 (DB10), Tower of Ascension (ToA), and Hall of Heroes (HoH). He contributes both in survivability and consistent damage over time.
To fuse Veromos, the required monsters are Kumae (Dark Yeti), Mikene (Water Undine), Argen (Wind Vampire), and Eintau (Fire Lizardman). Kumae is a natural 3★ monster obtained through the Hall of Darkness Secret Dungeon, requiring 40 pieces to summon. Eintau is also a natural 3★ monster and must be raised to 4★ and max level. Mikene and Argen are natural 4★ monsters and must be leveled to 5★ and max level. The total mana cost to fuse Veromos is 500,000 mana.
Sigmarus (Water Phoenix)
Sigmarus is a powerful AoE nuker with a skill that scales off the enemy’s max HP, making him extremely effective in dungeons and boss content. He excels in GB10, DB10, Elemental Dungeons, ToA, and Labyrinth. His leader skill boosts the HP of allies in dungeons by 44%, greatly increasing survivability.
To fuse Sigmarus, the required monsters are Arang (Wind Nine-tailed Fox), Jojo (Fire Joker), Susano (Water Ninja), and Mina (Water Martial Cat). Arang is fused from Prilea, Hina, Kahli, and Konamiya. Jojo is fused from Garoche, Cassandra, Kuhn, and Chichi. Susano is fused from Icaru, Kahn, Dagorr, and Tantra. Mina can be purchased from the Guild Shop. All materials must be awakened and leveled appropriately before fusion. The total mana cost to fuse Sigmarus is 500,000 mana.
Other Notable Fusion Monsters
Baretta (Fire Sylph) is commonly used in Tower of Ascension due to his AoE crowd control and continuous damage.
He is fused from Fao, Mei, Sharron, Lukan, and Shakan, and his fusion cost is 100,000 mana. Xiong Fei (Fire Panda Warrior) is a key unit for Raid Level 5 (R5) and Necropolis, and is fused from Qebehsenuef, Shailoq, Nubia, Ragion, and Sieq, costing 500,000 mana.
Jeanne (Light Paladin) is a versatile tank and crowd controller, used across PvE and PvP content.
She is fused from Harmonia, Rebecca, Kai’en, Dagora, and Aeilene, also costing 500,000 mana.
Katarina (Wind Valkyrja) is a powerful single-target nuker, often used in Guild Wars and Arena.
She requires Arang, Mikene, and Baretta, and costs 500,000 mana to fuse
Veromos is widely recognized as a core early-game fusion priority due to his utility in multiple PvE scenarios. Sigmarus follows closely behind as a top-tier fusion damage dealer. These monsters form the backbone of many beginner strategies and are instrumental in clearing key game content efficiently.
The Fusion Process: Step-by-Step
The fusion system in Summoners War: Sky Arena provides a reliable and strategic method to acquire powerful monsters by combining specific units through the Fusion Hexagram. This process not only gives access to essential monsters for progression but also helps players make consistent progress without relying entirely on random summons. Here’s a detailed guide on how to complete the monster fusion process from start to finish.
The Fusion Hexagram becomes available once your account reaches level 17. Even before unlocking the building, players can begin gathering the required fusion materials by summoning, farming, or purchasing them through various in-game methods. Early preparation can significantly speed up the fusion process once the building is accessible.
To begin, determine which monster you want to fuse. Common early-game targets include Veromos (Dark Ifrit) and Sigmarus (Water Phoenix). For Veromos, the required fusion materials are Kumae (Dark Yeti), Mikene (Water Undine), Argen (Wind Vampire), and Eintau (Fire Lizardman). For Sigmarus, the necessary components are Arang (Wind Nine-tailed Fox), Jojo (Fire Joker), Susano (Water Ninja), and Mina (Water Martial Cat). Each of these monsters may in turn require other monsters to be fused first.
Once you’ve identified the materials needed, the next step is to acquire them. Monsters can be summoned through various scrolls like Unknown Scrolls, Mystical Scrolls, or Attribute Scrolls. Some materials, such as Kumae, Tantra, Cassandra, Kuhn, Chichi, and Dagorr, can be obtained from Secret Dungeons available on specific days in the Hall of Elements. Secret Dungeons require collecting monster pieces—usually 40 pieces for a 3★ unit.
Players often farm these dungeons themselves or join others through invites in the public chat, particularly in channel 1050, which is widely used for Secret Dungeon coordination. Other monsters can drop from scenario stages—such as Prilea in Kabir Ruins or Garoche in Vrofagus Ruins—or be purchased from the Guild Shop, such as Mina (Water Martial Cat). Some monsters also occasionally appear in the Magic Shop or can be received through the Temple of Wishes.
After obtaining all the required monsters, they must be leveled up and evolved to meet the fusion requirements. Generally, monsters used to fuse a five-star monster must be five-star units themselves, fully leveled and awakened. Exceptions include natural 3★ monsters like Kumae, who only need to be evolved to 4★ and max level. Evolution requires both leveling the monster and sacrificing other monsters or Rainbowmons, which are available from gameplay rewards and the Guild Shop.
Once leveled and evolved, all fusion materials must be awakened. Awakening is done using elemental essences collected from the Hall of Magic and the elemental Halls of Fire, Water, Wind, Light, and Darkness. These halls open on different days of the week, with all available from Friday to Sunday. Awakening requires various combinations of low, mid, and sometimes high-grade essences of the monster’s element and magic essences.
With all required fusion monsters fully leveled, evolved, and awakened, go to the Fusion Hexagram and select the target monster. If all materials meet the requirements, you will be able to proceed with the fusion. Five-star fusion monsters like Veromos and Sigmarus require 500,000 mana to complete the fusion. Four-star fusion monsters, such as Baretta, require a lower cost of 100,000 mana.
By following these steps carefully, players can efficiently build fusion monsters that are vital to game progression. Veromos stands out as a key early fusion due to his cleansing and sustained damage, making him extremely useful in Giants B10, Dragons B10, and ToA. Sigmarus is another powerful fusion option, providing high AoE damage and utility for dungeon and boss content. Completing these fusions sets the foundation for a strong early and mid-game team, ensuring smoother advancement through PvE content.
Tips and Strategies for Efficient Fusion
Efficiently fusing monsters in Summoners War: Sky Arena requires planning, preparation, and smart resource management. Monster fusion is a long-term investment that rewards consistency, and following specific strategies can significantly reduce the time and resources needed to complete your fusions. Here are key tips to help you optimize the fusion process and progress faster.
Start by identifying which fusion monsters you want to prioritize early in your journey. Units like Veromos (Dark Ifrit) and Sigmarus (Water Phoenix) are common early targets due to their wide usability in PvE content. Planning these fusions in advance allows you to begin collecting materials as you play, even before unlocking the Fusion Hexagram, which becomes available at account level 17. Gathering materials ahead of time means you can immediately start fusing as soon as the building becomes accessible.
Keep an eye out for fusion support events that often reward players with key fusion materials or monster pieces. These events are especially helpful for new players, as they can drastically speed up the process of obtaining monsters like Veromos, who plays a critical role in early dungeon teams. Some events also align with awakening materials or leveling resources, making them even more valuable to participate in.
When gathering materials, familiarize yourself with fusion recipes and where to obtain each monster. Many components can be summoned from Unknown Scrolls, Mystical Scrolls, or found in Secret Dungeons, which rotate daily based on element. For example, Kumae (Dark Yeti), a requirement for Veromos, is farmed in the Hall of Darkness, which opens on Mondays. You’ll need 40 pieces to summon a three-star monster like Kumae from his Secret Dungeon. Similarly, materials like Tantra, Icaru, Kahn, and Dagorr—required for Susano, a Sigmarus fusion component—can be obtained through Secret Dungeons, scenario drops, and shop appearances. Use chat Channel 1050, a common hub for Secret Dungeon invites, to coordinate with other players when specific dungeons are available.
Don’t overlook the value of Unknown Scrolls. While they may not seem exciting, mass summoning them can yield a large supply of low-star monsters, which are essential for powering up, evolving, and awakening your fusion materials. These summons can also occasionally provide needed fusion pieces directly, making them useful beyond just fodder.
Pay close attention to star level requirements. Typically, materials for five-star fusion monsters must be evolved to five stars, fully leveled and awakened. An exception is Kumae, a natural three-star, who only needs to be evolved to four stars and max level. Use Rainbowmons, obtainable from the Guild Shop and game rewards, to help evolve your fusion materials efficiently.
Strategically plan your awakening process by checking which Hall of Elements opens on each day of the week. Farming the Hall of Darkness on Mondays, for example, provides the dark essences needed to awaken Kumae. Each monster will require low, mid, and sometimes high elemental essences, along with magic essences, so budget your energy and time accordingly. All fusion materials for monsters like Sigmarus must be fully awakened before fusion.
Ensure each fusion material is fully leveled to its max at the current star grade before attempting to evolve it to the next. This step is required before you can fuse the monster, and skipping it will prevent the process from going through. Leveling can be accelerated by using power-up material from scrolls or farming efficient experience stages like Faimon Volcano and Aiden Forest.
Keep track of your mana usage, as each fusion has a set cost. Five-star fusion monsters such as Veromos and Sigmarus each require 500,000 mana, while four-star fusion monsters, like Baretta or the materials used in the process, typically cost 100,000 mana. Planning ahead and maintaining a healthy mana reserve will ensure you don’t hit roadblocks when you’re ready to complete a fusion.
By following these strategies—planning ahead, farming efficiently, awakening methodically, and managing resources—you can streamline your monster fusion process and build a powerful roster that supports consistent progress through dungeons, PvE challenges, and beyond in Summoners War.
Conclusion
Monster fusion in Summoners War: Sky Arena plays a central role in player progression, offering a structured and reliable method to obtain powerful monsters without relying entirely on summoning luck. This system allows summoners to target specific units like Veromos (Dark Ifrit) and Sigmarus (Water Phoenix)—monsters that are essential for early and mid-game content, particularly in dungeons such as Giants B10 and Dragons B10. Planning fusions early not only saves time but also ensures more efficient resource allocation.
The Fusion Hexagram, which unlocks at account level 17, serves as the central hub for combining monsters. However, players can begin gathering the required fusion materials well before this level. Starting early allows summoners to fuse key units immediately once the building becomes available, accelerating overall progression. Efficient fusion planning involves collecting the necessary monsters through scrolls, scenario drops, Secret Dungeons, the Guild Shop, and the Magic Shop.
Fusion materials must meet specific conditions: they need to be leveled up, evolved to the appropriate star rating, and fully awakened using essences from the Hall of Elements and Hall of Magic. Awakening requires farming on specific days, managing energy use, and stockpiling essences. Fusing a five-star monster such as Veromos or Sigmarus also requires a mana investment of 500,000, making mana management another important consideration during the fusion process.
Veromos is especially valuable due to his passive ability to cleanse harmful effects and his effectiveness in dungeon teams. Sigmarus is also a high-impact fusion unit thanks to his AoE damage and scaling against enemy max HP, making him ideal for dungeon bosses and the Tower of Ascension. These units remain among the most reliable fusion choices to strengthen early-game rosters and establish a foundation for long-term success.
In summary, fusion is not just a side feature—it is a core mechanic that allows players to acquire strategic units, plan their progression with certainty, and reduce their reliance on random summons. With careful planning, resource management, and knowledge of fusion requirements, summoners can unlock some of the most impactful monsters in the game and push through PvE content more efficiently.
