To expound on the Noble Phantasms of the Servants from the Fourth War.
Lancer:
Gáe Buidhe: Golden Rose of Mortality
Rank: B
Type: Anti-Unit
A cursed spear that renders injuries unrecoverable. As damage from this spear lowers the upper limit of the target's HP, no matter what healing spell or regeneration ability is used, the target can only be healed up to the "point where the wound was borne". Dispelling of the effects is impossible and the only way to be rid of the curse is to destroy Gáe Buidhe or its master, Diarmuid.
Gáe Dearg : Crimson Rose of Exorcism
Rank: B
Type: Anti-Unit
A long spear that negates mystical defense. Armor crafted by mystical energy has no effect towards the attack of this spear. If equipment provided with mystical enforcement or other enchantment is hit against Gáe Dearg, the enchanment will not activate. This is a "Noble Phantasm killer" that in truth, can only be defended against by physical means. However, it can not undo contracts and curses made in the past nor the effects of already completed sorcery.
Saber is hit by both during a fight, and loses the use of her left arm as well as Invisible Air. Caster then attacks her with summoned monsters, but Saber is still able to destroy them with just her good arm.

Rider:
Via Expugnatio: Distant Trampling Domination
Rank: A+
Type: Anti-Army
A trampling style using the Noble Phantasm, Gordius Wheel, Wheel of Heaven's Authority. Two damage rolls, from the hooves of the divine bulls and wheels of chariot are made. In addition to the physical damage from both attacks, there are also lightning (the manifestation of Zeus) effects, and should the target fail its STR check, additional damage will be dealt.
Aionian Hetairoi: Army of the King
Rank: EX
Type: Anti-Army
Allows the planar manifestation as Servants of Iskander's personal guard, who vowed allegiance to him even after death and became Heroic Spirits together with their lord. The summoned warriors are all Master-less Servants, however each have the rank E- equivalent of the "Independent Action" skill, allowing materialization possible for a maximum of 30 turns.
Expugnatio has the destructive power of a modern day military bomber jet. Aionian Hetairoi is very similar to Archer's Unlimited Bladeworks, only instead of weaponry, it's men.

Caster:
Prelati's Spellbook: The Text of the Spiralled Sunken Citadel
Rank: A+
Type: Anti-Army
Also known as the R'lyeh Text, a spellbook with a cover made of human hide and originally belonged to Prelati, a comrade of Caster's. Using blood and flesh as mediums for materialization, Prelati's Spellbook summons monstrous creatures that are neither spiritual bodies nor Phantasm Beasts, but those which exist in a dimension with entirely different natural laws.
The spellbook is a summoning grimoire; the book itself is alive and responsible for the incantations that summon and revive demonic monsters. Caster does not actually read the spells recorded on the pages of Prelati's Spellbook, but is able to freely command the spellbook.
Caster uses this agains Saber, but even with one arm disabled by Lancer, she hacks through each one. Supposedly a hundred of them.

Berserker:
Unnamed Noble Phantasm
Rank: ?
Type: Support (Self)
The black-armoured knight appears to have a Noble Phantasm that allows him to use any weapon (even objects like telephone poles, fighter jets, or the Noble Phantasms of other Epic Spirits) as his own Noble Phantasm, which gives him the power to defend himself against Archer's Gate of Babylon and hold his own against Saber. However, this Noble Phantasm demands a higher level of mana from his Master in order to materialize (several times higher than other Servants) and tends to be difficult to control because the Black Knight's presence is unstable as a result of his Master's weakening body and the higher amount of mana required to materialize Berserker-class servants.
Berserker has three Noble Phantasms, blurred in his status page, only this unnamed one having been shown. This one is used when Berserker is attacked by Archer and Gate of Babylon. Berserker uproots a telephone pole, swats the projectiles out of the air, and starts throwing them back. Old Gil is forced to retreat.

Assassin:
Zabaniya: Delusional Image
Rank: B+
Type: Anti-Unit (Self)
By having a soul that, while being a single entity, is split into multiple parts, division of its own spiritual body potential and physically manifestation of those parts as multiple Servants is possible. Splitting into a maximum 80 bodies is possible. Generation of a self-ego that is unaware of itself (among the bodies) is also possible.
Archer 'kills' one of these images and Kirei and Resei Kotomine withhold Assassin for the rest of the War. Kirei kills Tokiomi Tohsaka (Rin's Father) and takes Archer as his Servant instead, nulling the one with Assassin after his father dies of old age.
