Fusion Monsters are an essential part of progression in Summoners War, allowing players to combine specific monsters to create powerful Natural 5★ units without relying on summoning luck. These fusions provide access to some of the strongest and most useful monsters in the game, especially for PvE content like dungeons and raids. However, building them requires careful planning, farming specific monsters, and investing time into leveling and awakening each component. In this guide, we’ll break down everything you need to know about Fusion Monsters and how to efficiently create them.

Fusion Monster Tier List

This tier list is ranked from the best Fusion Monster to the worst, although all of them are still useful.

Sigmarus (Water Phoenix) – Fusion Monster Overview

Katarina (Wind Valkyrja) – Fusion Monster Overview

Katarina is primarily a PvP-focused Fusion Monster, most commonly used in Guild War Offense and Siege Battles. While she can also be used in Raid content (R5), there are generally better and more consistent options available for that role, especially in the late game where rune requirements are much higher.

She is not a top priority fusion, but when built correctly, Katarina can secure quick wins in specific Guild War and Siege matchups thanks to her high burst damage. However, her effectiveness can still be inconsistent due to the RNG nature of her Skill 3, even after recent buffs that made it slightly more reliable. This makes her more of a situational cleave option rather than a stable offensive pick.

In some cases, she can also be used in Guild War Offense and even Water Labyrinth boss teams, particularly when paired with units like Jamire. Jamire is an excellent partner for Katarina, as he allows her to reset and use her burst more effectively, creating strong synergy. If you happen to summon Jamire, Katarina becomes significantly more valuable—and in that situation, fusing her becomes a very strong option.

Veromos (Dark Ifrit) – Fusion Monster Overview

Veromos is a fusion support monster who was once a staple pick for early-game progression but has become less essential in recent years, mainly due to buffs to Sigmarus that made Sig a more attractive beginner fusion option.

He can still be very useful in early to mid-game PvE content, helping players progress through Giants, Dragons, and ToA/ToAH. When paired with units like Belladeon, he also provides solid utility in Guild War Offense, especially for newer accounts. His kit offers consistent debuff cleansing and sustain, which makes him reliable during progression stages.

However, as you move into the mid to late game, Veromos tends to fall off in priority. Once you gain access to strong immunity monsters, he becomes less necessary, since full immunity is generally more effective than periodic cleansing. That said, he can still find niche use in Siege Battles, particularly as a counter to units like Jeanne.

If you have already fused Veromos, he will continue to support your account across many areas of the game early on. If not, he is generally not a high priority fusion anymore, as his long-term value is limited compared to newer or more versatile options.

How to Create Fusion Monsters

Fusing monsters in Summoners War allows you to create powerful units by combining specific monsters. It’s a great way to obtain strong monsters without relying on luck from summons, but it does require time, planning, and resource management.

Step 1: Go to the Fusion Hexagram

Head to the Fusion Hexagram building on your island. This is where all monster fusions take place and where you can view the requirements for each fusion monster.

Step 2: Select the Monster You Want to Fuse

Choose the fusion monster you want to create. Each fusion will show four required monsters, along with their elements, star grade, and awakening requirements.

Step 3: Prepare the Required Monsters

You’ll need to:

• Summon or farm the required monsters
• Level them up to the required level
• Evolve them to the correct star grade
• Awaken them (most fusions require awakened monsters)

Each required monster may also need its own evolution materials, so be prepared to farm quite a bit.

Step 4: Place the Monsters into the Hexagram

Once all four required monsters are ready, place them into the Fusion Hexagram slots. Double-check that everything meets the requirements before proceeding.

Step 5: Complete the Fusion

Confirm the fusion, and the game will combine the materials into your new monster. Keep in mind that the materials are consumed during the process, so make sure you don’t need them elsewhere.
