About classes | Class list | Skill list | Extended 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[edit]

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

Important Points[edit]

  • 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 40-100 EMP 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 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[edit]

  • 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.
Icon Name Rank ☆1 ☆2 ☆3 Prio Notes
ZenithAtk.png ATK Bonus - 500 1500 3000 ★★★★

Free 3000 base ATK with no strings attached. Should always be your first purchase.

ZenithDef.png DEF Bonus - 1% 3% 5% ★★

A solid perk combined with the HP perk.
Recommended for classes you bring to challenging content and HL.

ZenithHP.png HP Bonus - 300 600 1000 ★★★

Quite a large amount of health, great to keep MC alive.
High priority when using Splitting Spirit or together with the DEF Bonus perk.
Situational pick for Sword Master as increased HP interferes with Slime Blasting in a party of four.

ZenithHeal.png Heal Bonus - 1% 3% 5% ★★

Limited usefulness since most classes don't use heals.
Most useful for party heals so Bishop, Sage and Superstar with Nine-Realm Harp may want to consider obtaining this perk. Note that Summons that heal is affected by this EMP since the healing originates from the Main Character. For example, 4★ Lucifer.

ZenithSkillDmg.png Skill DMG Bonus - 1% 3% 5%

Low priority.
Most useful for Sidewinder and Hermit until near the damage cap. Will allow reaching damage cap with less debuffs on your foes.

ZenithModeBar.png Overdrive Curbed Bonus - 1% 3% 5%

Low priority.
Mode bar will increase less in normal mode and decrease more in overdrive mode.

ZenithDebuffRes.png Debuff Resistance Bonus - 1% 3% 5%

Low priority since Veil and Clarity exists.
Can be useful for Superstar when combined with a Harp, Soul Soloist, 4★ Medusa (Summon) and this perk which can reach over 80% debuff resistance total.

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 like Wind Dancer, together with a Superlative Weapon or for the current Unite and Fight.
Elemental Resistance Bonus - 1% 3% 5% Arguably the worst EMP perk set, Elemental DMG Cut Bonus is an investment that only works when MC has Hostility Up as it only applies to MC. However, assuming it stacks additively, means that those unfortunate enough to not have Carbuncles can live without an 3★ summon - but the rest of their team will still die. Extremely unrecommended.
ZenithCADmg.png C.A. DMG Bonus - 1% 3% 5% ★★★ Due to new CA damage cap which is harder to hit, not as bad as before. Recommended when you want to hit cap CA on HL bosses' DEF. Especially useful in fights without debuffs like Ultimate Bahamut (Raid).
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.

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

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 that use some of their charge bar for some of their abilities.

ZenithEnergy.png Energy Bonus - 1 2 3 ★★

Sword Master/Glorybringer only. Usefulness is based on energy cost of mainhand used. Generally considered poor.

ZenithBulletCasting.png Bullet Casting Bonus - Lvl 2 Lvl 3 Lvl 4 ★★★★ Gunslinger only. Gains access to superior Bullet Casting, allowing forging of superior bullets.
Can be removed after desired bullets are casted.Verification needed.
ZenithCritHit.png Critical Hit Bonus 151 1% 3% 5% Unlike the character perk version which is very powerful, this only adds 5% damage bonus with a 5% chance to occur which is terrible.
ZenithTotalHP.png Total Party HP Bonus 155 300 600 1000 ★★★★ A direct upgrade to the HP Perk. Always useful.
ZenithDef2.png DEF Bonus II 155 1% 3% 5% ★★ Extra DEF. Always a safe choice for HL.
ZenithSpecWpnDmg12.png Specialty WPN 1 DMG Bonus II 160 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

ZenithDA2.png Double Attack Bonus II
165 1% 3% 5% ★★★★ Increased charge bar gain is always useful.
ZenithTA.png Triple Attack Bonus
165 1% 3% 5% ★★★★ Increased charge bar gain is always useful.
ZenithCADmg2.png C.A. DMG Bonus II 170 1% 3% 5% ★★★ Due to new CA damage cap which is harder to hit, not as bad as before. Recommended when you want to hit cap CA on HL bosses' DEF. Especially useful in fights without debuffs like Ultimate Bahamut (Raid).
ZenithDmgCap.png DMG Cap Bonus 170 3% 6% 10% ★★★★ Increases the maximum amount of damage that the MC can do by 10%. Extremely powerful.
ZenithBurstDmg.png Chain Burst DMG Bonus 175 1% 3% 5% Chain Bursts often hit damage cap with finished grids.
ZenithDodge.png Dodge 176 1% 2% 3% 3% Dodge rate can be powerful, but it's too inconsistent to be recommended.

ZenithCADmg3.png C.A. DMG Bonus III 190 1% 3% 5% ★★★ Due to new CA damage cap which is harder to hit, not as bad as before. Recommended when you want to hit cap CA on HL bosses' DEF. Especially useful in fights without debuffs like Ultimate Bahamut (Raid).
ZenithDmgCap2.png DMG Cap Bonus II 195 1% 3% 5% ★★★★ Not as useful as DMG Cap Bonus, it's still a solid pick as it's 5% increased damage cap.
ZenithSpecWpnDmg13.png Specialty WPN 1 DMG Bonus III 200 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

Star Cap[edit]

The total number of stars that can be added to each class at a time is determined by Extended Mastery Level, which is a function of your Rank.

Star Cost[edit]

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
