Final Fantasy Wiki

Scion created to rid the world of its impurities by swallowing them within himself, in opposition to Nabriales the Majestic, scion of light. The world, however, was more filled with impurity and corruption than even the gods dared imagine, and having swallowed it all, the once beautiful Cúchulainn was transformed into a hideous thing, a deity of filth, and so did he turn against his creators. Wherever his feet should fall, there all life withers to dust.

Cúchulainn the Impure is an optional level two Esper in Final Fantasy XII. He is associated with the element of Poison and fought in the Garamsythe Waterway under Rabanastre, perhaps attracted by the surrounding sewage (or the cause of it).

Cúchulainn's license costs 50 LP, and he requires two Mist Charges to summon.


Cúchulainn is associated with the Poison and the zodiac sign Scorpio, the Scorpion, shown by his poisonous nature. He is also referred to as the Vrishchika Ascendant, which is the Sanskrit name of its zodiac sign as used in Jyotish (Hindu) astrology. To strengthen his relation to the Scorpio sign, he is given an enormous tail hidden inside his body.

Cúchulainn is based on a Lucavi from Final Fantasy Tactics. Cúchulainn returns in Final Fantasy XII: Revenant Wings as a Rank 2 Melee Water summon, unlike the other Final Fantasy XII Espers who are Rank 3.


The player must complete the Wraith and White Mousse Hunts to get the control of the sluice gates in the Garamsythe Waterway. From the first central area, with the save crystal, the player should see four sluice gate switches: 3rd, 4th, 10th, and 11th area.

The steps to accessing the area where the player can find Cúchulainn are as follows:

  1. In the Central Waterway Control, the player must activate the sluice gates No. 3 and No. 10.
  2. The player must move to the No. 10 Channel into the No. 3 Cloaca Spur. In the south end, one must activate the No. 1 South Waterway Control switch.
  3. The player must return to deactivate the No. 3 and 10 sluice gates, then activate the No. 4 and 11 sluice gates.
  4. The player must move to the No. 11 Channel into the No. 4 Cloaca Spur. In the south end, they must activate the No. 1 North Waterway Control switch.
  5. Finally, the player must return to the Central Waterway Control, and turn off the No. 11 switch, and turn on the No. 3 panel.

Now only sluice gates No. 3 and No. 4 should be on and the player can access the middle of No. 1 Cloaca where Cúchulainn is fought. It is recommended to save the game before engaging him.

After being fought as a boss, Cúchulainn's license can be purchased on the License Board for 50 LP.

Unlocked abilities in Zodiac versions[]

Esper licenses sometimes unlock licenses that could not otherwise be reached. Cúchulainn's license will appear on all boards, but once chosen by a character, will disappear from all other boards. In The Zodiac Age version, the player can choose two license boards for each playable character, and activated licenses are activated on both boards if present.

Cúchulainn allows access to the following licenses on these boards:

  1. Also achieved with Ultima


Cúchulainn costs two Mist Charges to summon, and cannot receive Bubble status.

In the Zodiac versions, Cúchulainn gains Bio, and depending on which character his license is given, Cúchulainn unlocks new abilities for the user: Libra for the White Mage, Wither for the Uhlan, a Magick Lore augment to the Machinist, Black Magicks spells Firaga, Thundaga, Blizzaga and Sleepga for the Red Battlemage, a Battle Lore augment for the Knight, the Shades of Black Technick for the Foebreaker, Stamp for the Bushi and the White Magicks Protectga and Shellga for the Shikari.

Status effects[]



Cúchulainn is a boss fought in the middle of the Garamsythe Waterway. Cúchulainn is also fought in the Zodiac versions' Trial Mode at stage 42 along with four Foobars. The battle's special attribute is that health is constantly drained from all active party members. Cúchulainn routinely casts Bio and Malaise and uses Impure to inflict Disable and Immobilize. He also casts Invert, inverting the target's HP and MP.



Cúchulainn is an Irish mythological hero who appears in the stories of the Ulster Cycle, as well as in Scottish and Manx folklore. "Cú" is the Irish word for hound—"Cúchulainn" is literally "Hound of Chulainn". "Cúchulainn" is technically mispronounced in the series, being closer to "coo-hullen" as audible in the following reading from Irish myths by Ronnie Drew via youtube.

The son of the god Lugh and Deichtine, sister of the king of Ulster, he was originally named Sétanta, but gained his better-known name as a child after he killed Chulainn's fierce guard-dog in self-defense, and offered to take its place until a replacement could be reared. At the age of seventeen he defended Ulster single-handedly against the armies of queen Medb of Connacht in the epic Táin Bó Cúailnge.

It was prophesied that his great deeds would give him everlasting fame, but that his life would be short—one reason he is compared to the Greek hero Achilles. He is known for his terrifying battle frenzy or "warp spasm", in which he becomes an unrecognizable monster who knows neither friend nor foe. He fights from his chariot, driven by his loyal charioteer Láeg, and drawn by his horses, Liath Macha and Dub Sainglend.

It is also referred to as the Vrishchika Ascendant, which is the Sanskrit name of its zodiac sign as used in Jyotish (Hindu) astrology.
