Fantomon System Concepts and Functions
Fantomon aren't just cute pets that follow you around—they're also powerful companions that can influence the outcome of battle! In the game, Fantomon serve as "support companions" and can boost the overall strength of the protagonist and the team through passive bonuses or skill effects. Although Fantomon don't fight directly like characters do, they play an indispensable role in battle by providing attribute boosts, triggering skills, and offering defensive support. A good Fantomon setup can make clearing stages, farming bosses, and fighting in PvP much easier.
Detailed Explanation of Fantomon Types and Roles
Fantomon can generally be divided into three main roles: DPS, Guardian, and Support. Each role focuses on different attributes and skill effects.
Offensive Fantomon:
Enhancing Attack, CRIT Rate, CRIT DMG, or adding effects such as Defense Reduction and Armor Break is key to increasing the damage of DPS classes. For example, "Dark Night Emperor" is one of the representative Offensive Fantomon, with reliable Defense Reduction and strong burst damage capabilities.

Guardian Fantomon:
Focuses on survivability effects such as Defense, shields, damage reduction, and healing. This type is suitable for pairing with tanks or for improving survival in high-pressure combat scenarios.
Support Fantomon:
They provide acceleration, buffs, crowd control, or recovery effects, improving the team's overall combat power, support capabilities, and battle tempo. For example, the Fantomon "Forest Fairy" is considered a support type and provides Speed and buff effects.
Fantomon quality tiers: Purple → Epic → Legendary → Miracle. While top-tier Fantomon have outstanding effects, they are also harder to obtain.
Fantomon Acquisition Mechanism
Obtaining Fantomon or its shards is the prerequisite for building your lineup and strategy. Here are several common ways to get them:
Summon / Gacha Pool:
You can directly obtain Fantomon through Fantomon Summons or the Gacha Pool. In the early stages of the version, resources are relatively abundant, so you're encouraged to pull more to build up your Fantomon roster.
Event Rewards or Limited-Time Missions:
The game may distribute Fantomon or shards as rewards during certain events, anniversaries, or festivals.
Bond Shop Exchange:
Some Fantomon shards or entire Fantomon can be exchanged in the Bond Shop. However, since the exchange cost is usually quite high, it's recommended that you carefully consider whether it's worth exchanging for them.
Synthesis/Evolution/Shard Merge:
Some Fantomon can improve their quality and strength through Shard Synthesis, leveling up, or evolution. Even if you are not using certain Fantomon right now, they may still provide additional combat power through stat bonuses, which is why many guides recommend "keep them as soon as you pull them."
Fantomon Training and Enhancement Process
After obtaining a Fantomon, the key is how you develop its true potential. Below are the common enhancement methods:
Resonance Level Mechanics
The game introduces the concept of "Resonance Level": increasing your Resonance Level also raises the base level of the Fantomon you own at the same time, reducing the burden of having to train each Fantomon separately. Public guides mention that you should prioritize raising your Resonance Level first for your main team.
Skill Upgrade and Ascension
Many Fantomon have exclusive skills. You can consume materials or fragments to increase their skill levels, and can even advance them to unlock additional passive effects.

Affinity or Bond Increase
You can increase Affinity/Bond by interacting with Fantomon, giving them items, or completing specific tasks. Once Affinity reaches the required level, you may unlock additional attribute boosts or special bonuses.
Resource Allocation and Upgrade Priority
Because materials and resources are limited, it's generally recommended to strengthen your main Fantomon first and raise its Resonance Level so your other Fantomon can benefit as well. Spreading your resources too thin by building too many Fantomon can instead lead to wasted resources. Many guides emphasize that "focusing your resources" is the most efficient strategy.
Recommended Fantomon Pairings for Each Class
Based on each character's role and the in-game data, here are some Fantomon pairing ideas and recommendations for several class types:
Sage (Dark Priest / Healer)
Depending on how you build the Sage, you can play it as support/Healer or as a Dark Priest DPS. If you want to focus on damage, Dark Night Emperor is recommended, as it can trigger an AoE defense-reduction attack on the first turn, making it an ideal choice for the Dark Priest route.
If you want to focus more on the Healer role, then Angel of Dawn is recommended. It can prevent a character from taking fatal damage and heal them, increasing your margin for error.
During the transition period, "Forest Fairy" was often regarded as a versatile Fantomon that could provide both speed and support in a variety of situations.
Melee DPS / Warrior Class
Game forums and strategy guides recommend "Dark Night Emperor" as the top Fantomon choice for high-DPS classes. Paired with its defense-reduction burst effect, it performs exceptionally well in Dungeons and World Events.
If you need more stability, you can also use a Guardian Fantomon to shore up your defenses or sustain in prolonged fights.
Tank/Guardian Class
Tank-type characters have high survivability requirements, so you should prioritize Guardian-type Fantomon or those that can reduce damage taken or provide shields to improve overall durability.
If your resources allow, you can also pair them with a Support Fantomon to keep the team's rhythm stable.
General Pairings and Multi-Class Applications
Some Fantomon have more balanced attributes, making them suitable as transitional or backup options for a variety of class scenarios.
In different Dungeons or PVP and PVE scenarios, you can switch Fantomon setups based on your needs to optimize performance.
Fantomon Selection and Strategy Recommendations
To help you avoid investing resources incorrectly and improve efficiency, I’ve summarized the following suggestions:
Prioritize your core Phantom Beasts: Don’t try to raise too many Fantomons in a short period of time. First, choose 1–2 Phantom Beasts that best suit your class and playstyle, then focus your resources on developing them.
Pull Strategy: According to the guide, even if you pull a Fantomon you can't use right now, it can still provide stat bonuses, so it's fine to do more pulls early on to build up your collection.
Exchange with caution: items in the Bond Shop generally cost quite a lot to redeem, so unless they are core Fantomons or their shards, you shouldn't exchange for them casually.
Leave yourself some flexibility: since the developers may adjust Fantomon skills and balance in future version updates, it's recommended that you don't invest all your resources in Fantomons that haven't yet been confirmed to be top-tier.
Switch based on the scenario: use an Offensive Fantomon in situations that demand high burst damage, and choose a defensive/support type in high-pressure situations or when survivability is a priority.
Frequently Asked Questions (FAQ)
Q: Why should you keep the Fantomon you pulled even if you can't use it for now?
A: Many guides mention that even if you aren't using that Fantomon for the time being, simply having it will still grant additional attribute bonuses (possibly up to 20%).
Q: Why is Resonance Level important?
A: Resonance Level can simultaneously increase the base level of all your Fantomons, making it a system that reduces the burden of raising them individually. Many players recommend focusing on increasing Resonance Level first.
Q: Which Fantomon should beginners/free-to-play players choose?
A: In publicly available materials, the commonly recommended transition choices are "Forest Fairy" and "Purple Cloud Beast," which offer a better balance between support and damage output.
Q: Will version updates change the ranking order of Fantomon strength?
A: Yes. The official Patch Notes previously included adjustments to Fantomon skills and the Materialization Effect.
