Lancer (ランサー, Ransā) is the Lancer-class Servant of Kayneth El-Melloi Archibald during the Fourth Holy Grail War. His true name is Diarmuid Ua Duibhne (ディルムッド・オディナ, Dirumuddo Odina), the first warrior of the Knights of Fianna. He is also known as Diarmuid of the Love Spot, for a curse given to him by a young girl that makes all women who see his face fall in love with him. Ultimately, Grainne, the wife of Fionn mac Cumhaill, Diarmuid's lord, fell in love with him. Grainne took advantage of a geis to make him run away with her, which only led to tragedy.
Powers and Stats
Name: Lancer, Diarmuid Ua Duibhne
Classification: Lancer-class Servant
Powers and Abilities: Superhuman Physical Characteristics, Master Spearman, limited Mind Manipulation (His Love Spot causes women to fall in love with him), Healing and Magic Negation with Gáe Buidhe and Gáe Dearg, Soul Manipulation (All Servants can consume souls to replenish their magical energy), Intangibility and Invisibility in spirit form, Immunity to conventional weapons, Resistance to Magic (Including effects such as Petrification, Spatial Manipulation, and Mind Manipulation)
Lifting Strength: Unknown
Striking Strength: Mountain Class
Durability: Mountain level
Standard Equipment: His Noble Phantasms, Gáe Buidhe and Gáe Dearg.
Intelligence: True to his class, Lancer is a truly exceptional spearman, easily wielding two spears of varying lengths with blinding speed and grace, taking even the King of Knights by surprise in their first encounter, putting her completely on the defensive with only a single spear while his back was turned to her. He is extremely calm in combat and a brilliant tactician, fooling Saber into thinking that he had abandoned Gáe Buidhe only to kick it up and activate it, successfully landing a clear blow on one of her hands to keep her from swinging her blade properly. In addition, he is manipulative enough to try and charm Saber with his Love Spot and would have manipulated Berserker if he had been convinced that the Holy Grail War was not the honorable battleground he made it out to be.
Weaknesses: Lancer adheres strictly to the rules of chivalry and thus refuses to use dishonorable tactics and may endanger his chances of winning a fight for the greater good.
Notable Attacks / Techniques:
Gáe Buidhe: Yellow Rose of Mortality: A cursed spear, given to Lancer by Manannán mac Lir, the king of fairies. He usually keeps it wrapped in cloth to seal its abilities and hide his identity. Its effects are passive in nature, and its True Name does not need to be released to activate it. Its curse of mortality is always active, and it comes into effect whenever Lancer injures someone with it. The spear lowers an opponent's maximum health limit, and thus prevents the healing of the injured area through any means, as his opponent is already at full health. While it is only really an inconvenience at best for a Servant, against a normal being, any blow would quickly become fatal as bleeding would not cease. The curse can only be dispelled with the destruction of Gáe Buidhe or the death of Lancer.
Gáe Dearg: Crimson Rose of Exorcism: A demonic spear, given to Lancer by his foster father, Aengus Óg. He usually keeps it wrapped in cloth to seal its abilities and hide his identity. As with Gáe Buidhe, its effects are passive in nature, and its True Name does not need to be released to activate it. The spear negates magical enchantments and effects. It ignores projections made from magical energy entirely, and chips away things like forcefields and enchantments with every blow. Items that act as a source of magical energy have their connections to their recipients completely severed. It cannot nullify magecraft that has already been completed, such as curses, and its effects last only so long as Gáe Dearg's tip is contact with the object. In addition, it is not powerful enough to destroy magical objects on the level of Noble Phantasms.
Tale of Tragic Love: Devotion to Grainne: A technique involving both spears that appeared in Fate/Unlimited Codes, Lancer runs his opponent through with a tossed Gáe Daerg to pin them to the ground, before repeatedly attacking his downed target with Gáe Buidhe in a series of spinning attacks. He then finishes them by tossing Gáe Buidhe as his target, engulfing them in bright light.
Magic Resistance: An innate ability that grants protection against magical effects. Unlike the Resistance effect that merely rejects Magical Energy, this ability cancels the spells altogether. Lancer's Magic Resistance is enough to negate spells with a chant below three verses, and makes it hard for spells on the level of High-Thaumaturgy and Greater Rituals to effect him.
Eye of the Mind (True): The heightened capacity for observation, refined through experience. Lancer's rank in this skill is B, greatly improving his chances of winning due to being able to calmly analyze all possibilities and choose the appropriate course of action, even if his chance of winning is only one percent.
Love Spot: A curse that makes women fall in love with Lancer when they see his face. It's unconscious and Lancer has no control over it, though magic resistance can negate its effects.
