How To UseEdit
In order to be able to use a holy weapon there are two prerequisites. First, the character must have major holy blood from the dragon god whose blood pact granted the ability to wield the weapon he or she is attempting to use; this gives a star (*) rating in that weapon type. Second, they must either obtain the holy weapon through story means or start out with it, because it is impossible to sell holy weapons to the pawn shop.
Swords are the most abundant type of holy weapon other than magic, and the player eventually gains control of all of them.
The Sacred Sword once wielded by Crusader Baldur, the Paladin, that the house of Chalphy is famed for. Its stat boosts are greater than any other holy weapon other than the Book of Naga and its boosts go to Skill Speed and especially Resistance, the latter of which allows the wielder to be easy assigned as a mage-killing unit. It is used by Sigurd and Seliph, the central protagonists of the 1st and 2nd Generations, respectively.
The Divine Sword of the royal family of the Kingdom of Isaach passed down by Crusader Od, the Sword Saint. Seen only in the 2nd Generation, it gives Speed boosts that turn Shannan, its only wielder, into a near absolute attack-dodging ace (despite a usually mediocre Speed growth purely based on his character attributes), and it also gives a Skill bonus, which increases the chance Starlight Sword Skill will activate. It should be noted that Ulster and Larcei can wield the Balmung through a glitch if their father is Chulainn.
The Demon Sword of Agustria entrusted to the lords of the Dominion, descended from Crusader Hezul, the Black Knight. It gives the skill Critical to whomever possesses it along with a high Skill boost and a decent Resistance boost, turning it into the best Baron-killing weapon, a resilient foe encountered often during the game. It is used against you by Eldigan in the 1st Generation and later under the player's command by Ares in the 2nd Generation .
Both of the holy spears come from the Thracian peninsula, and both are used against the player at one point or another, but the player obtains direct use of one of them and indirect use of the other near the end of the game.
The Earth Spear of the royal family of Leonster, relinquished by Crusader Noba, the Spear Knight. It gives reasonable boosts in Defense, Skill, and Strength. The player gets the use of it for a short time with Quan in the 1st Generation. His daughter Altena uses it against you for a short time in the 2nd Generation, but after she is successfully recruited, she will be able to use it to fight for the player's cause near the end of the game.
The Heavenly Spear of the kings of Thracia, obtained from Crusader Dain, the Dragon Knight. It is identical to the Gáe Bolg, but it gives a bonus to Speed in place of Skill. It is used by Travant against Quan, in possession of the Gáe Bolg, and Ethlyn when both appear in Chapter 5 on your side (but as NPCs not under player control) in the 1st Generation. It is later used against you by Arion during Chapter 9 and in the Final Chapter in the 2nd Generation, but if Altena talks to him in the Final Chapter, Areone will come to your side (not under player control, but as an allied NPC).
There is only one of these, and the player unfortunately does not get the opportunity to make use of it.
The Sacred Axe of the house of Dozel was once brandished by Crusader Neir, the Axe User. It is best used defensively, giving a large bonus to Defense and a more modest bonus to Resistance. While it is the only physical holy weapon with 1~2 range, making it rather dangerous in the hands of a unit placed on a Gate, it also has drawback of having 20 Weight (quite high) and 70 Hit% (a tad disappointing). It is used by Lombard in the 1st Generation and by one of his grandsons, Brian, in the 2nd Generation. Worthy of note is that Danann has the potential to use it, even if he is never shown doing so.
Again, there is only one, but this time, the player gets to make much more extensive use of it.
The Sacred Bow bestowed by Crusader Ulir, the Bow User, to the house of Jungby. The holy weapon only gives a modest boost to strength and speed, but additionally grants the Live skill. It is used on your side twice, by Brigid in the 1st Generation and later her son, Febail, in the 2nd Generation (assuming Brigid was paired up).
There is just one staff, and it is usable by the player.
The Holy Rod of Edda enshrined by Crusader Blaggi, the High Priest, it has the power to revive any dead character. It is first possessed by Claud in the 1st Generation, but can later be passed down to Coirpre (if the player pairs Claud with Sylvia), or Ced (if the player pairs Claud with Erinys) in the 2nd Generation.
The most inclusive category of holy weapon, merged because there is only one weapon of each type of magic.
The Flame Magic of house Velthomer unleashed by Crusader Fjalar, the Magic Fighter, is used twice by Arvis; once in the 1st Generation and a second time in the 2nd Generation. It gives stat bonuses to Resistance, Defense, and Magic.
The Thunder Magic of house Freege commanded by Crusader Thrud, the Magic Knight, is used against you five times: Once by Reptor in the 1st Generation, once by Bloom and on three different occasions by Ishtar in the 2nd Generation. It gives a generous bonus to Skill and also slightly increases Speed.
The Wind Magic of Silesse guided by Crusader Sety, the Wind User, is used by Lewyn in the 1st Generation, and later on by Ced, Arthur or Coirpre (depending on who Lewyn is paired with) in the 2nd Generation. It stat bonuses it grants the wielder are identical to those of the Balmung.
The Holy Magic of Grannvale's ruling house, Belhalla, appointed by Crusader Heim, the Saint. Naga gives very generous bonuses to Speed, Skill, Defense, and Resistance and is only used by Julia in the 2nd Generation.
The Dark Magic created by the Dark God Loptyr It not only grants 5 points to Resistance to its chosen vessel, but also halves all incoming damage to him before defense is even factored in (unless the Book of Naga is used against it). The player encounters Loptyr twice; both times it is wielded by Julius in the 2nd Generation.
