Basic Fire Build – How to Build Fire from Preparation into Seasons
Hey there, fellow Infinity Kingdom player! Today, I’m going to walk you through my approach to building and preparing a Fire team as we move through the preparation stages and into the early seasons (especially Season 1). Fire is one of my favorite elements to play because it’s packed with high-impact damage, strong control, and a lot of flexibility in how you build your lineup. Whether you’re free-to-play (F2P), a mid-tier spender, or somewhere in between, Fire can make a huge impact in large-scale PvP. Let’s dive in!

Why Choose Fire?
Fire has always been appealing due to its massive burst damage and the potential for surprisingly strong control setups. Even if you’re on the losing side of a rally or a large battle, the Fire Dragon’s breath and your Immortals’ fast burst abilities often ensure you still deal meaningful damage. This makes Fire extremely accessible for F2P and mid-tier players who want a team that consistently leaves its mark.
Another big perk is that Fire is effectively the only “true” free-to-play element in Infinity Kingdom. You can build a complete Fire lineup from scratch without spending money, thanks to Gilgamesh or Cyrus (obtainable through King of the Hill and other in-game activities). Granted, it won’t let you outclass top-tier spenders, but it does give you the highest possible ceiling for a F2P build.
For mid-tier spenders, Fire is also a great choice, especially later in the game when you can combat whale-level Shadow or Holy teams more effectively. Historically, Fire was even the go-to meta for some top players before certain nerfs and adjustments, which shows just how potent it can be.
Early Progress and Immortal Choices
During the preparation stage and early seasons, you’ll likely start piecing together your Fire Immortals and gradually refine their skills.

Right now, the biggest challenge is that Wu Zetian can be a bit harder to obtain compared to before because other immortals have become faster to build. However, she remains incredibly powerful, and you do get her for free over time, so it’s worth the investment if you plan to run Fire.

To fill in gaps while you’re building Wu Zetian, you can use other spellcaster immortals like Merlin, Medb, or Gilgamesh in the meantime.

I personally spent a bit to unlock Seondeok for my backline, but with her recent nerf, I’m leaning more toward switching to Cyrus later on. That said, Seondeok can be very convenient early in the game because she’s easy to get from the Golden Path and Daily Coins store.

Recommended Fire Compositions
Below are some composition goals you can aim for as you head into Season 1. These examples are tailored to varying budgets, so you can pick whatever best fits your style:
- Wu, Seondeok, Trajan, Hippolyta
- Wu, Cyrus, Trajan, Hippolyta

Or, for more free-to-play oriented versions:
- Wu, Cyrus, William, Hippolyta
- Wu, Gilgamesh (or Medb), William, Hippolyta
These lineups give you high burst potential and some control, especially if you decide to emphasize Cyrus’s stuns or Seondeok’s crit bursts.
Note that before you unlock unique artifacts, you can run highly succesful fire setups without Hippo by stacking crit synergies. Note that this guide is from before unique artifacts where released. Once you obtain Unique Artifacts you should revert into a Hippo-Trajan frontline if possible or run a William-Hippo frontling. Read more about the old crit-build here.

Skill Selection and Early Game Strategy
Fire teams depend on skill synergy, so unlocking and placing the right skills early on is crucial. Many skills you pick up for Fire can later transition to a secondary or hybrid lineup as you gather better Fire-specific skills. Some early and universally useful skills to invest in include Combo, Onslaught, Wisdom, Rage, Adrenaline Rush, Blessing of War, Blessing of Defense, Fighting Master, Oaken Guard, Resist, Berserk, Toxic Nova, Chaotic Blade, and Chase.
Once you start unlocking more advanced skills, consider Malice, Weakness, Energy Suppression, and Rage Blessing for your Fire team, gradually moving older skills like Onslaught and Combo onto your hybrid lineup. If you opt for a Cyrus-based control team, you might want to grab Purification and Assist to handle debuffs and prolong battles, which can be a lifesaver against powerful Shadow teams.
Personally, I’m picking up Demonic Contract and Purification from the Wisdom Well. If you’re on a tight budget, don’t worry—you can wait until these skills appear in cheaper five-day bundles later on.
Planning for Season 1
I’m excited to test both Seondeok and Cyrus builds when I hit Season 1. These are my current skills working pretty well as I am leveling into the later levels of the Tower of Knowledge.

Here’s a peek at how I am going to re-arrange their skills once possible:
- Cyrus Version
- Wu Zetian: Annihilation, Chase, Fighting Master
- Cyrus: Assist, Weakness, Oaken Guard (or Resist), and possibly Purification later
- Trajan: Energy Suppression, Blessing of Rage, Malice
- Hippolyta: Adrenaline Rush, Demonic Rage (plus possibly Death Breath or Energy Burst)
- Seondeok Version
- Wu Zetian: Annihilation, Chase, Rage
- Seondeok: Fighting Master, Anger, Adrenaline Rush
- Hippolyta: Malice, Energy Burst, Death Breath
- Trajan: Weakness, Rage Blessing, Energy Suppression
I’m still experimenting with Demonic Contract to see whether it fits better on Wu, Seondeok, or Hippolyta. Results will vary depending on how quickly the battles end, so I’ll keep testing and refining the lineup.
An Older, Proven Free-to-Play Setup
If you want a tried-and-tested option without fussing over the newer skill changes, you can use something like:
- Seondeok (or Gilgamesh) with Death Breath, Anger, Fighting Master
- Empress Wu with Annihilation, Chase/Concentration, Toxin Nova
- Hippolyta with Weakness, Oaken Guard, Blessing of War
- William (or Trajan) with Malice, Energy Suppression, Blessing of Rage/Fighting Will

This setup has proven effective in the past, although I believe you can squeeze out even more power with the newer strategies mentioned above.
Dragon Focus
Don’t forget that your Fire Dragon is a critical part of this element’s power. Focus on upgrading the dragon’s breath attack first, then the passive skill, and lastly its crit modifier. As the game progresses, you’ll unlock more specializations for the dragon, but we’ll talk about that in a future guide once I have some in-season experience to share.

Summary
Building a Fire team in Infinity Kingdom is a blast. It gives you massive burst damage, potent control options, and an accessible path to endgame viability—especially for F2P or mid-tier spenders. You can adapt your composition and skills to fit your budget and playstyle, whether that means going all-in on Wu Zetian’s magic damage, focusing on Cyrus’s stuns and control, or mixing in Seondeok’s crit bursts to keep your opponents off-balance.
As you head into Season 1 or beyond, remember to prioritize skill synergy and keep refining your Immortal lineup. The flexibility of Fire means you have plenty of room to experiment, and if you invest wisely in Immortals and skills, you’ll find yourself well-prepared for the challenges ahead. Good luck, and may your Fire Dragon’s flames scorch all who stand in your way!
