I looked back on my submission and noted Tristan already had magic resistance. I added riding according to the Type moon wiki's base container for Sabers and the changes you asked for, lemme know if you think he needs anything or he's a bit too much.

True name: Sir Tristan
Class Name: Saber
Nicknames: The Child of Sadness
Alignment: Lawful Good
Servant of: Sygila Murmirnea
Catalyst For Summon: A lock of hair from a lover
Weapon(s): Failnaught, Curtana
Wish: To be reunited with Iseult.
Personal Skills:
Harp of Healing: Rank C
In ancient society, the harp was highly regarded as appeasing evil spirits. Tristsan's harp was renowned through Camelot and was known for his ability to play and sing just as much as his skill as a warrior. His skill with the instrument is such that he is capable of purging mental interference and restoring psychological stability to those who listen to his music. However, the accuracy of projectiles and polearms suffer a large Rank Down within hearing range.
Admonishment of the King of Knights: Rank B
Tristan's denouncement of the King of Knights as heartless cut deeply, and his poetic strengths let him decry his opponent's merits similarly. They lose one ongoing enhancement effect and he reduces the amount of variance on their activities. Impossible feats relying on fate or luck or one in a million chances are made even more unlikely while Admonishment is active, functionally reducing the target's luck while under the effects of Admonishment by one rank.
Grace of Unexpected Birth: Rank B
Born into an unhappy environment without knowing his parents, Tristan's unfortunate circumstances of birth altered his worldview, granting him a second sense regarding people's intentions, and adaptability granted only to those born to unfortunate circumstances. Tristan has moderate resistance to penalties from visual obstructions, and movement obstructions.

Noble Phantasms:
Name: Failnaught: Fantasia of Lamentation Rank B+
Type Anti-Army
Not truly a bow but rather a magical harp that can rip air to create sound vacuums that he can fire at his target, shredding the target apart on strike. The disorienting sounds of Failnaught's attacks can pierce through a target's physical defenses and receives an innate bonus against targets weak to holy sacraments. However Tristan's fire rate is compromised by his Saber class and while he can still fire powerful sonic booms with impeccable accuracy, he cannot string lighter shots together at a rate that is useful for pressuring advancing opponents anymore, forcing him to rely more on Curtana for aggression.

Name: Curtana The Sword Of Mercy
Quote:
None
Rank: C
Type: Anti-Unit
Curtana The Sword of Mercy-A blunted, damaged sword that belongs to Sir Tristan Knight of the Round, said in later years to be comparable to swords like Durandal and Joyeuse in quality even despite significant wear. The blade features a decorative 'running wolf' mark down it's length a gilt-iron hilt, a wooden grip bound in wire, and a leather sheath bound in crimson velvet with gold embroidery. While the varied ownership of the blade has muddied it's story somewhat, accounts involving Tristan state that the tip broke off within the skull of Morholt during their duel.
While inactive, it's edge is completely blunt and Tristan relies on his strength to beat his opponent's into submission. However upon evoking it's True name the damaged blade is enveloped in moonlight, extending it's length and granting it an edge of unparalleled sharpness, and burning the enemies it strikes. While it lacks the flash and strength of it's rival blades' explosive finishing power, its strength lies in it's lower upkeep cost, allowing prolonged usage of the enhanced weapon's performance to grant Tristan the upper-hand against other combatants in close quarters, allowing him to maintain an unnatural grace and speed for a weapon of it's dimensions.
