Players who started Sword x Staff during the first day of the Growth Trial should now be close to unlocking the free Legendary Fantomon Selector Chest. This reward is one of the most important free items in the game because it lets you choose a powerful pet that can help your build for a very long time.
Even if you are not on Day 7 yet, this guide is still useful. Every player will eventually reach the selector reward, so knowing which Fantomon works best for your class can save you from making a bad choice later. While almost every Legendary Fantomon has some use, certain pets clearly perform better depending on whether you play Sorcerer, Duelist, Sage, or Knight.
Why You Should Skip Kells
Before talking about the best choices, many players recommend avoiding Kells from the selector chest. The main reason is simple: Kells can already be farmed from the PvP Arena Shop. Because of that, spending your valuable selector on him is usually not worth it.
Players can buy Kells shards regularly using Arena currency, and getting extra PvP attempts daily helps speed up the process. The refresh cost is fairly cheap, especially if you only buy a few extra entries every day. Over time, farming Kells naturally becomes much easier compared to obtaining other Legendary Fantomons.
Kells is still a decent pet for DPS-focused builds like Sorcerer, Duelist, and offensive Sage setups, but since the game already provides another way to get him, most players are better off choosing a harder-to-obtain option from the selector chest.
Best Fantomons for Sorcerer
Sorcerers benefit the most from damage-focused Fantomons because the class already has strong offensive scaling. The three strongest options are usually Cealetus, Silvereai, and Herbotem.
Cealetus
Cealetus is considered one of the strongest picks for pure DPS Sorcerer builds. Many Sorcerers use Light-element spells, which makes the extra Light damage bonus extremely useful during both PvE and boss fights. If your goal is maximizing damage numbers, Cealetus is easily one of the safest choices.
Silvereai
Silvereai is another strong offensive option thanks to its attack and speed buffs. After the caster takes action, the pet grants bonus attack and speed for one turn. This buff becomes even stronger after upgrading the skill level, making it valuable for players who want faster turns and higher overall DPS.
Herbotem
Herbotem is very useful for players pushing difficult content with lower combat power. Since Sorcerers do not have reliable healing or lifesteal, Herbotem’s healing effect helps survivability a lot. It can also remove debuffs, which becomes important in harder stages and raids.
For aggressive builds, Cealetus usually wins. For survivability and progression pushing, Herbotem becomes a strong option.
Best Fantomons for Duelist
Duelists already have lifesteal and sustain built into their kit, so their ideal pets focus more on improving attack speed and raw damage instead of healing.
Silvereai
Silvereai is arguably the best overall Duelist pet right now. The permanent uptime on attack and speed buffs works perfectly with Duelist gameplay because the class relies heavily on fast attacks and constant pressure. The boost feels very noticeable during long fights and boss encounters.
Cealetus
Cealetus remains another excellent pick for Duelists who want more burst damage. Extra offensive scaling always works well for damage-focused builds, especially when paired with strong skill rotations.
Terragon
Some Duelists also use Terragon because it deals physical damage and can reduce enemy attack power. While it is not usually the top recommendation, it still works for players who want more utility in battle.
Overall, Silvereai and Cealetus are still considered the strongest choices for most Duelist players.
Best Fantomons for Sage
Sage is a special case because the best pet changes depending on whether you play healer, summoner, or damage-over-time builds.
Mandragora for Healer Sage
For support-focused Sage players, Mandragora is currently one of the strongest choices available. Its healing support effect works extremely well with ally-targeting skills, giving additional healing during combat.
Most other Legendary Fantomons do not provide much value for heal-focused Sages, which is why Mandragora stands out so much despite not being part of the SS selector discussion.
Silvereai for Summoner Sage
Summoner Sage builds benefit heavily from Silvereai because summons inherit part of the player’s stats. The attack and speed buff helps increase overall summon performance, making it one of the strongest scaling options available.
Cealetus for DPS Sage
For damage-over-time or offensive Sage builds, Cealetus performs very well thanks to the extra offensive scaling. Players who focus more on dealing damage instead of healing can safely choose either Cealetus or Silvereai.
Best Fantomons for Knight
Knight builds usually focus on defense, survivability, and frontline utility. Because of that, their best Fantomons differ slightly from the other classes.
Armopy
Armopy is widely considered the best overall Knight pet because of its shield generation. After building stacks, it grants a strong shield effect that greatly improves survivability during long fights. Tanks benefit a lot from this extra layer of protection.
Terragon
Terragon is another strong option for Knights who want a balance between defense and offensive utility. The attack reduction effect can help reduce incoming damage from enemies during difficult encounters.
Herbotem
Knights who prefer self-sustain can also use Herbotem. The healing and debuff removal effects work nicely for solo content or situations where healers are unavailable.
Silvereai and Cealetus
Some DPS-oriented Knight builds also experiment with Silvereai or Cealetus for higher damage output. While not as common, they can still work depending on your gear setup and playstyle.
Which Fantomon Should You Pick?
There is no single perfect answer because each class and build plays differently. However, some choices are clearly safer than others depending on your role.
Here is a simple breakdown:
- Sorcerer: Cealetus, Silvereai, or Herbotem
- Duelist: Silvereai or Cealetus
- Sage Healer: Mandragora
- Sage DPS/Summoner: Silvereai or Cealetus
- Knight: Armopy, Terragon, or Herbotem
If you are unsure, Silvereai is probably the safest all-around offensive option for most DPS classes thanks to the consistent attack and speed buffs.
The free Legendary Fantomon Selector Chest is one of the best rewards currently available in Sword x Staff, especially for free-to-play players. Picking the right pet early can make progression much smoother, whether you focus on PvE farming, raids, or pushing difficult stages.
While many Fantomons are usable, choosing one that matches your class strengths is usually the smartest move. Offensive players will often prefer Silvereai or Cealetus, while defensive and support players may get more value from Armopy, Herbotem, or Mandragora depending on their setup.
