Independent Action

is the ability to remain independent even when rejecting the Magical Energy supply from one's Master; the ability that allows for action even in the absence of the Master. Independent Action is the Class Skill of the Archer and Faker classes.
At higher ranks, it is also possible to remain for extended periods of time in this world without an established contract. It is both useful and troublesome depending on the disposition of the Servant and the rank of Independent Action. Acting in autonomy from the Master's Magical Energy supply, the Master can concentrate their own Magical Energy on large spells, or the Servant will be fine even in the case they cannot supply Magical Energy due to injury. The downside is that they can be harder to control and keep by their side, making the only true way to command them is by utilizing Command Spells.
Rank 	User(s)
EX 	Kiso Yoshinaka, Noah, Sugitani Zenjuubou, Super Orion
EX 	Artoria Pendragon Alter (Swimsuit)
EX 	The employer to be taken care of is still around, but that is a separate matter. The servicing spirit of a maid should be free... something spontaneous, and not something to be forced into by someone else; such is the conviction that let Alter gain this fearsome Independent Action Skill. Because of this Skill, her normal parameters are just slightly lower than usual.Fate/Grand Order material V — Profile of Artoria Pendragon Alter (Swimsuit), translated by Clyton at Beast's Lair.
EX 	Ashwatthama
EX 	The ability to act even in the absence of a Master. As long as Incarnation of Rage continues, Ashwatthama will head anywhere to defeat the enemy.
EX 	Gilgamesh (Fate/EXTRA CCC)
EX 	The Servant can operate without a Master. However, to use Noble Phantasms of great magical energy consumption, backup from the Master is necessary.Fate/EXTRA material
EX 	Gilgamesh (Ruler)
EX 	As a Ruler and the Observer of the Ritual, he does not have a Master and is free to act as he pleases.
EX 	Koyanskaya of Light
EX 	Surprisingly and terrifyingly enough, Koyanskaya of Light doesn't need a Master. She abides by her Master's Command Spell for a single reason: her pride telling her she'll never break a promise or contract.Fate/Grand Order material XIII - Koyanskaya of Light's Profile translated by ComunCoutinho
EX 	Meltryllis (Swimsuit)
EX 	The ability to be self-reliant for a while even if the Magical Energy supply from her Master is cut. As an Alter Ego that is "a different aspect of a certain being", she is capable of acting independently even without a Master. Having awakened to not only ballet but also figure skating, her "Star Upon a Stage" has been further refined. Before her charisma, the contractor would surely rather be the Servant who supports her. Perhaps.
EX 	Paris
EX 	Paris himself does not possess the Independent Action skill, however, because Apollo is attached to his Saint Graph Archer possesses this fearsome ability. At EX rank, Independent Action allows for nearly any act, whether related to combat or otherwise, to be undertaken without support from the Master (short of repeated use of his Noble Phantasm).
EX 	Sieg
EX 	A subspecies of Servant possession. Other than requiring magical energy whenever he goes into combat, he is no different than any other human being in all aspects. Normally, he would also be of a typical human age, but...
EX 	Surtr (Lostbelt)
EX 	He’s able to accomplish incinerating all land on Earth without receiving a mana supply. As Ophelia's servant, Surtr doesn't possess any special ability such as Independent Manifestation or Independent Action. Thus, breaking the contract between Ophelia and Surtr renders him just like another Servant without a Master.
A++ 	Thia Escardos
A++ 	That much is obvious because he's a living being, but even if he was a Servant, he would still be able to operate for a long time.
A++ 	Ishtar (Fate/strange Fake)
A++ 	Because she's currently descended in and fused with a homunculus body.
A+ 	The Servant can operate without a Master. With a Rank of A+ that exceeds even A, the support of a Master is unnecessary even while unleashing a large amount of Magical Energy. It is an ability that bends the rules and allows for the continued materialization of Servants even after the conclusion of a Holy Grail War.
A+ 	James Moriarty, Gray, Calamity Jane
A+ 	Gilgamesh (Fate/stay night)
A+ 	Gilgamesh gained this level of Independent Action by being showered with the contents of the Holy Grail, resulting in him being completely incarnated and granting him the ability to remain materialized after a Holy Grail War. He would continue to survive as an existence with a physical body.Fate/complete material III
A+ 	Euryale

A+ 	Despite the ability to act independently, Orion cannot do any action without Artemis.Fate/Grand Order material II — Profile of Orion, translated by Kinalvin at Reddit.
A+ 	Fujino Asagami
A+ 	It's not like she prefers solitude, somehow or other, she has a bad habit of taking strolls by herself. Tailing is her strong point. Running out of magical power should be extremely painful to her, but since her sense of pain is weak, she does not notice it.
A+ 	Florence Nightingale (Santa)
A+ 	The ability to stand independent for a while without the supplying magical power from a Master.
She fights all alone on her mission.
A+ 	Ushiwakamaru (Swimsuit)
A+ 	There were many animal friends at the mountain of Kurama. That’s why I’m quite fine even if I’m alone!
A 	It is possible to take action even without a Master. However, to use Noble Phantasms of great magical energy consumption, backup from the Master is necessary. At Rank A, it is possible for a Servant to stay in the world for about a week without a Master.

A 	Hassan of Serenity
A 	A Skill granted to Hassan because of her conducts during her lifetime where she went into enemy territories unaided and moved to infiltrate for a long period of time according to the situation presented. Even without a Magical Energy supply from her Master, it becomes possible for her to remain materialized for about a week at most.Fate/Grand Order material IV - Hassan of the Serenity, p.130-137, translated by Clyton at Beast's Lair.
A 	Meltryllis
A 	An Alter Ego which exists as "another aspect of an existence" can act alone even without a Master. Meltryllis is more geared towards Independent Action, but this seems to be due to her heart which finds "an étoile (star) shining on the stage all by herself" beautiful.
A 	Mysterious Heroine XX
A 	It’s unthinkable that she was a former Saber class, but she has inherited the skill she had in the class from before becoming a Foreigner without change.
「That’s because, in severe missions, cool-headed self-assessment is required at times」, she herself is convinced with a triumphant look.
A 	Okita Souji Alter
A 	As a Counter Guardian, it’s possible to act independently. The high rank is because she was tailored for the purpose of manifesting under despairing circumstances and annihilating the target solo or disappearing taking them with her.Fate/Grand Order material VII Okita Souji (Alter) Translated by ComunCoutinho
A 	Okita Souji Alter (Swimsuit)
A 	In the appearance of a swimsuit-clad Guardian of the Deterrent, it’s possible for her to act independently. The manifestation in a desperate situation, with the singular goal of annihilation, elopement and destruction have resulted in an adjustment of purpose, so the rank is still high.Fate/Grand Order - Okita Souji Alter (Swimsuit) profile translated by Justiciar_Jyggalag at Reddit
A 	Saika Magoichi
A 	Can act even in the absence of the master. Saika is confident in her ability to carry out operations alone, but she get hungry easily so she need a lot of portable food. If a huge amount of magical power is required, such as using a Noble Phantasm, the Master's backup is required.
A 	Shiki Ryougi (Assassin)
A 	"Maybe it doesn't matter if I have a Master, or something. Independent Action is enough to make you think of these things in such a manner. However, whether or not I have enough magical energy, I disappear when it gets lonely, so a Master is essential Mikiya-kun!"Fate/Grand Order material III — Profile of Shiki Ryougi (Assassin), translated by King of Padoru at Beast's Lair.

B 	Protea, who has a powerful Mana Core, can preserve her own Saint Graph even without a Master.
For Protea, the Master is not "a necessary keystone to bound her / a source of mana supply", but just "the one who summoned her".
In the case that a Master succeeded in summoning her in a Holy Grail War, the "duty to supply the Servant with mana" would disappear for that Master.
It depends on the Master whether they see it as an advantage or as a predicament.
