About classes | Class list | Skill list | Extended Mastery | Master Level | Ultimate Mastery


Once a class reaches level 20, its Extended Mastery is unlocked, offering a variety of bonuses through perks. The bonuses are acquired by spending Extended Mastery Points (EMP) to add stars to the perks. The total number of stars you can apply to each class at once is based on your current rank.

Obtaining EMP

  • You gain 1 EMP per 36,000 EXP acquired on a Level 20 class.
  • CP square.jpg CP ×50 or Gem square.jpg Gem ×20 can be converted to 1 EMP without limit.
  • No resources are refunded when removing stars.

Important Points

  • EMP are shared between classes; gaining EMP on one class does not restrict where you spend it.
  • On the other hand: Stars/Bonuses are not shared between classes (eg. buying the ATK perk on Fighter will not affect ATK on Berserker)
  • You will need at least 100, and up to 200-400 EMP in the long run for each Row IV class you unlock, so do not spend too many on Row III classes.
  • Never spend EMP on Row I or Row II classes as they see very little use compared to Row III and IV.
  • EMP has an upper limit of 99,999 for how much you can hold free at once. Once you reach this upper limit, you won't gain any EXP until you spend EMP, thus allowing you to earn EMP once again.

Perk list

  • Unlike other characters' Extended Mastery Perks, the third star for each perk is usually the most efficient for the Main Character.
  • Thus, it is usually worth investing three stars anywhere you're willing to invest one star.
  • For general use, the highest priority perks are ATK, Double Attack, Debuff Success (if relevant) and HP.

ZenithDebuffAcc.png Debuff Success Bonus - 1% 3% 5% ★★★★

High priority on classes where you cast debuffs.
Excellent from Omega battles and onward. As the debuff resistance of bosses keeps increasing this perk becomes more and more valuable. Even if 5% sounds small it can be the difference between winning and losing.
Performs even better when combined with Status DebuffResDown.pngDebuff Res. DownDebuff resistance is lowered
.

Elemental ATK Bonus - 1% 3% 5% ★★

Elemental ATK Bonus is situational as it only works for the specific element. The more elements a class is used with, the lower the priority of this bonus.
However, for specific cases it can be valuable, such as when a class is mostly used with one element, when using a Superlative Weapon, or during a Unite and Fight.

Elemental Resistance Bonus - 1% 3% 5%

Among the least useful perks if not the worst one. Similar to defense, it reduces incoming damage; but it only works for one element. Many bosses use off-element attacks ranging from early-game Yggdrasil (Raid) to late-game Super Ultimate Bahamut, meaning if the MC does get hit, there's a chance this perk won't work. It may have a subtle niche helping improve MC survivability in specific content like Unite and Fight or teams with Elemental Switch; but with how limited you are on EMP stars, there are still other perks more worth your while.

ZenithCADmg.png C.A. DMG Bonus - 1% 3% 5% ★★★

Recommended when you want to hit CA cap in HL raids with high boss DEF. Especially useful in fights without debuff like Ultimate Bahamut (Raid).
Priority increases to ★★★★ for classes that focus on maximizing CA damage, such as Icon job 300301.pngChrysaor, Icon job 420301.pngCavalier, Icon job 450301.pngRelic Buster, Icon job 220301.pngKengo and Icon job 270301.pngRising Force, or any class intended for one-turn-kill (OTK) while keeping skill usage minimum.

ZenithSpecWpnDmg1.png Specialty WPN 1 DMG Bonus - 1% 3% 5% ★★

All Specialty WPN DMG Bonuses can be extremely powerful or borderline useless, depending on the grid used. Very powerful when used with Weapon s 1040505100.jpg Cosmic WeaponRandom SSR Cosmic Weapon.s.

ZenithSpecWpnDmg2.png Specialty WPN 2 DMG Bonus - 1% 3% 5% ★★

All Specialty WPN DMG Bonuses can be extremely powerful or borderline useless, depending on the grid used. Very powerful when used with Weapon s 1040505100.jpg Cosmic WeaponRandom SSR Cosmic Weapon.s.

ZenithDA.png Double Attack Bonus
- 1% 3% 5% ★★★★

Multiattack boosts on the MC are valuable to keep their charge bar ahead of the party or to keep up with characters who have boosts to their own multiattack rate, enabling chain bursts sooner. Especially useful for classes with skills that consume some of their charge bar.

ZenithEnergy.png Energy Bonus - 1 2 3 ★★

Icon job 230201.pngSword Master / Icon job 230301.pngGlorybringer only. Usefulness is based on energy cost of mainhand used. Generally considered poor.

Star Cost

Each star added to a perk increases the cost of additional stars, eg.

  • The first star you add costs 1 EMP; the second and third each cost 2 EMP; 26 through 30 each cost 11 EMP
  • Removing stars will similarly reduce the cost, making it more efficient to remove multiple stars at a time before replacing them
  • Check the table below for the cost of a given star
