---

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.

• See Character Extended Mastery Perks for the perks accessible to characters who are not the MC.

Obtaining EMP

• You gain 1 EMP per 36,000 EXP acquired on a Level 20 class.
• CP ×50 or 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.

Icon	Name	Rank	☆1	☆2	☆3	Prio	Notes
	ATK Bonus	-	500	1500	3000	★★★★	Free 3000 base ATK with no strings attached. Should always be your first purchase.
	DEF Bonus	-	1%	3%	5%	★★	A solid perk combined with the HP perk. Recommended for classes you bring to challenging content and HL.
	HP Bonus	-	300	600	1000	★★★	Quite a large amount of health, great to keep MC alive. High priority when using  Splitting SpiritConvert caster's HP to charge bar3% charge bar for every 250 HP consumed, up to 100% charge bar. (Consumes up to 50% of current HP.) or together with the DEF Bonus perk. Situational pick for Sword Master as increased HP interferes with Slime Blasting in a party of four.
	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.
	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 debuff on your foes.
	Overdrive Curbed Bonus	-	1%	3%	5%	★	Low priority. Mode bar will increase less in normal mode and decrease more in overdrive mode.
	Debuff Resistance Bonus	-	1%	3%	5%	★	Low priority since  VeilAll allies gain VeilDebuffs will be nullified (1 time) "Veil" is an unofficial name used by the wiki for this status effect. Its actual in-game name is "Immune.". and  ClarityRemove 1 debuff from all parties. exists. Can be useful for Superstar when combined with a Harp,  Soul SoloistHarp: Inflict 30% Debuff Res. DownDebuff resistance is lowered Strength: 30%Base Accuracy: 200% on all foes. All allies gain 30% Debuff Res. UpDebuff resistance is boosted Strength: 30%Base Accuracy: 200%Duration: 3 turns.

All allies gain 5% Debuff Res. UpDebuff resistance is boosted Strength: 5%Base Accuracy: 90%Duration: 3 turns., 4★ Medusa (Summon) and this perk which can reach over 80% debuff resistance total.
	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 Debuff 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%	★	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.
	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 Chrysaor, Cavalier, Relic Buster, Kengo and Rising Force, or any class intended for one-turn-kill (OTK) while keeping skill usage minimum.
	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 Cosmic WeaponRandom SSR Cosmic Weapon.s.
	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 Cosmic WeaponRandom SSR Cosmic Weapon.s.
	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.
	Energy Bonus	-	1	2	3	★★	Sword Master / Glorybringer only. Usefulness is based on energy cost of mainhand used. Generally considered poor.
	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.
	Bullet Casting Bonus	-	Lvl 2	Lvl 3	Lvl 4	★★★★	Soldier only. Gains access to superior Bullet Casting, allowing forging of superior bullets. Can be removed after desired bullets are casted.Verification needed.
	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.
	Total Party HP Bonus	155	300	600	1000	★★★★	A direct upgrade to the HP Perk. Always useful.
	DEF Bonus II	155	1%	3%	5%	★★	Extra DEF. Always a safe choice for HL raids.
	Specialty WPN 1 DMG Bonus II	160	1%	3%	5%	★★	See Specialty WPN 1 DMG Bonus.
	Specialty WPN 2 DMG Bonus II	160	1%	3%	5%	★★	See Specialty WPN 2 DMG Bonus.

	Triple Attack Bonus	165	1%	3%	5%	★★★★	Increased charge bar gain is always useful.
	C.A. DMG Bonus II	170	1%	3%	5%	★★★	Priority increases to ★★★★ for classes that focus on maximizing CA damage, or any class intended for one-turn-kill (OTK) while keeping skill usage minimum.
	DMG Cap Bonus	170	3%	6%	10%	★★★★	Increases the maximum amount of damage that the MC can do by 10%. Extremely powerful.
	Chain Burst DMG Bonus	175	1%	3%	5%	★	Chain Bursts often hit damage cap with finished grids.
	Dodge	176	1%	2%	3%	★	3% Dodge rate can be powerful, but it's too inconsistent to be recommended.
	Critical Hit Bonus II	180	1%	3%	5%	★	Extra crit. It stacks directly with Critical Hit Bonus I, bringing total bonus to 10% chance to deal 10% additional damage.
	Total Party HP Bonus II	185	300	600	1000	★★★★	Even more HP.
	C.A. DMG Bonus III	190	1%	3%	5%	★★★	See C.A. DMG Bonus II.

	DEF Bonus III	225	1%	3%	5%	★★	Extra DEF. Always a safe choice for HL raids.
	Skill DMG Cap Bonus	230	3%	5%	10%	★★★★	As damage cap for skill damages is also often hit with finished grids, it is a solid upgrade. Very high priority for classes that focus on skill damages, such as Nighthound, Lumberjack, Monk and Robin Hood.

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
