What Are Fantomons in Sword X Staff?
Fantomons are companion creatures that fight alongside your character, providing valuable stat bonuses, passive abilities, and extra damage during combat.
Although they’re unlocked relatively early, many players underestimate just how important they become during mid and late-game progression.
A well-developed Fantomon can make difficult content much easier while also boosting your farming efficiency.
Why Fantomons Are So Important
Your Fantomons contribute much more than extra attacks.
Depending on the companion, they may provide:
- Increased Attack
- Magic Damage
- Critical Hit Chance
- Healing
- Defensive buffs
- Crowd control
- Elemental damage
- Team-wide support effects
Choosing companions that complement your class is often more effective than simply selecting the highest rarity available.
Best Fantomons for Damage Classes
High-DPS characters should prioritize companions that increase offensive potential.
Look for Fantomons with abilities that:
- Increase Attack
- Boost Critical Rate
- Improve Critical Damage
- Enhance Skill Damage
- Reduce enemy defenses
These companions help clear both campaign stages and boss encounters much faster.
Best Fantomons for Tank Builds
Tank classes benefit from companions that improve survivability.
Useful effects include:
- Health regeneration
- Damage reduction
- Shields
- Defense buffs
- Enemy debuffs
These abilities allow you to survive difficult encounters while protecting your teammates.
Best Fantomons for Support Characters
Support classes should focus on utility.
The best companions often provide:
- Healing
- Cooldown reduction
- Mana recovery
- Buff duration
- Team-wide stat increases
These abilities become increasingly valuable during multiplayer activities.
Should You Upgrade Every Fantomon?
No.
Upgrade materials become limited surprisingly quickly.
Instead:
- Pick one primary companion.
- Develop one backup companion.
- Save resources until stronger Fantomons become available.
Concentrating resources produces much better results than upgrading your entire collection.
How to Strengthen Fantomons
- Leveling them regularly.
- Increasing their star rank.
- Equipping available enhancements.
- Unlocking passive skills.
- Participating in pet-related events.
Many seasonal events offer rare upgrade materials that are difficult to obtain elsewhere.
Common Fantomon Mistakes
- Investing in too many pets.
- Ignoring passive abilities.
- Choosing rarity over synergy.
- Forgetting to upgrade companions after leveling their character.
- Neglecting event rewards.
Remember that a lower-rarity Fantomon with excellent synergy can outperform a stronger companion that doesn’t complement your class.
Best General-Purpose Fantomons
If you’re unsure which companion to build first, prioritize Fantomons that provide:
- Reliable damage
- Passive stat boosts
- Survivability
- Useful utility across multiple game modes
These companions remain effective regardless of future balance updates.
Final Thoughts
Fantomons are much more than cosmetic companions—they’re a core part of your overall progression in Sword X Staff. Choosing pets that complement your class, focusing your upgrade materials on a small number of companions, and participating in pet-focused events will help you maximize your Combat Power far more efficiently.
Whether you’re clearing campaign stages, tackling bosses, or competing in PvP, investing in the right Fantomon can make a noticeable difference throughout your adventure.
