Once a class reaches max level, 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.

For Origin classes (evolution of Row I classes), extended masteries are available from lvl 1, and any extended mastery upgrades from the original Row I class are inherited.

• 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 class at max level.
• For classes that can be uncapped, EMP will be gained from EXP earned at the current level cap (before uncapping).
• 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.

	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	★★★	A good amount of health, great to keep MC alive. High priority together with the DEF Bonus perk, or 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.) with low-HP grids.
	Heal Bonus	-	1%	3%	5%	★★	A small boost to both healing and healing cap. Most classes don't use heals, but it also affects healing from summon calls. Most notably this includes Transcended Lucifer, who is a common summon choice in hard content, and can be chosen as a friend summon even by those who don't have him. More valuable on classes that bring their own healing as well such as Sage, Iatromantis, or Ultimate Mastery Nekomancer
	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 Veil (1 time)Debuffs will be nullified (1 time) "Veil" is an unofficial name used by the wiki for this status effect.

	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, an Illustrious 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 EMP stars are, there are other perks that are more worthwhile.
	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%	★★	Boosts performance of weapons that match the first weapon specialty of the MC's class. Of little use unless using a grid that stacks matching weapon types for the MC. Some classes benefit from stacking matching weapons in a grid due to the class's passive skills, and are thus more likely to see benefit from this node.

	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.

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; 27 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
