Celestial Weapons act as the ultimate weapons in Final Fantasy X. Each character has their own unique weapon. Acquiring them and getting all of them to full power will require exploring many parts of Spira and completing many of FFX’s minigames. While Celestial Weapons don’t have any extra stats compared to normal weapons, they have a full set of passive abilities catered to the character, and hidden passives that help them deal more damage.
Obtaining Celestial Weapons
The weapons themselves are hidden throughout Spira, but will not appear until you obtain the Celestial Mirror. Some will require you to accomplish an additional task to appear.
However, just getting the weapon is not enough, since on its own it’s not very useful. All Celestial Weapons start off having the passive effect ‘No AP’, and three blank slots that you cannot fill. In order for the weapon to reach its full potential, you must obtain the Crest and Sigil that corresponds with the weapon.
The Celestial Mirror
Before you can find any Celestial Weapon, you must first get the Celestial Mirror. The first step in getting it requires you to go to Remiem Temple and race the champion chocobo there. Once you win the race, you’ll get the Cloudy Mirror, which you will need to turn into the Celestial Mirror.
To do this, you must go to the Macalania Woods and talk to a woman at the entrance who says she can’t find her husband. You can find him by moving two areas to the right, then one area up. Once you send him back, talk to either one of them until they tell you that their son has gone missing.
You must then head up the crystal walkway until you reach a fork that was previously blocked off. You will find the son at an altar. Examine the altar and the Cloudy Mirror will transform into the Celestial Mirror.
Upgrading Your Weapon
Once you gain the Celestial Mirror and find a character’s Celestial Weapon, you must find the Crest and Sigil that goes with it to upgrade it to its full potential. Once you find the Crest and Sigil, you must go back to the altar in the Macalania Woods and present the weapon to it.
There are two upgrades to fully power a weapon:
The first upgrade takes only the weapon’s Crest, and will add the passive ‘Double Overdrive’ to it. Most of them will also allow an Aeon to break their damage limit.
The second upgrade will take the Crest and Sigil and grant the weapon its full power.
Hidden Weapon Passives
While it is possible to get a normal weapon and give it all of the effects that fully realized Celestial Weapons have, the Celestial Weapons have hidden passive effects that make them stand out.
Arguably, the most important passive all the weapons share is that they ignore the enemy’s Defense. This means that physical attacks will never be mitigated by enemies (note that this effect doesn’t apply to Overdrives).
The weapons also scale their damage based on the characters’ HP/MP, depending on the weapon. Most weapons deal 100% damage if the character is at full HP/MP, with the only exception being Auron. In his case, the weapon’s damage is higher the lower his HP is, hitting 100% damage at 70% HP.
Each character has a unique Celestial Weapon, and they all have different effects, as well as different ways to obtain and upgrade them. Below is a short summary of each character’s weapon, and what is required to get their weapon at full potential.
Tidus’s Celestial Weapon is the Caladbolg, and is amongst the hardest weapons in the game to fully realize. The weapon is in the Calm Lands, but a man will be blocking the path to get to it. To get him to move, you must complete training on riding a chocobo, and beat the trainer’s time in a race. The path in the Northwest section of the Calm Lands will then open, and you can obtain the weapon.
The Sun Crest can be found in The Beyond within the Zanarkand Dome, where Yunalesa is fought. Any time after you beat the boss, you can go back to this area and go down either flight of steps. You will be teleported to another corner of the room, and the Crest will appear at the top of the stairs you ascended. In order to get the Sun Sigil, you must beat the chocobo trainer in the Calm Lands with a time of 0:00.
Yuna’s Celestial Weapon is the Nirvana. In order to obtain it, you must go to the Monster Arena and begin the side quest there, capturing the nine different monsters in the Calm Lands. Once the monsters are captured, the weapon will appear in front of the Monster Arena.
The Moon Crest can be found in an alcove on the beach of Besaid. The Crest is hidden to the right of the beach. To get the Moon Sigil, you must go to the Remiem Temple in the Calm Lands, and defeat all of Belgemine’s Aeons (you must obtain every Aeon in order to do this). Once you defeated her Magus Sisters you must send Belgemine, and the Moon Sigil will appear. Upgrading the Nirvana will allow Valefor to break the damage limit.
Wakka’s Celestial Weapon is the World Champion. You must place at least 3rd in a Blitzball tournament, then head to the Luca Café. Speak to the bartender, and she will give you the weapon if you have the Celestial Mirror.
The Jupiter Crest will appear after the party leaves Luca following the Blitzball tournament. It can then be found in a locker within the Besaid Aurochs’ locker room. The Jupiter Sigil can appear as the 1st place prize in a Blitzball league once you have obtained all of Wakka’s Overdrives. Upgrading the World Champion will allow Ifrit to break the damage limit.
Kimahri’s Celestial Weapon is the Spirit Lance, and is considered one of the harder weapons to fully upgrade. To obtain it, you must first go to the Thunder Plains and read the book on Gandof and the Qactuars in the Travel Agency. You will then need to pray to the three Qactuar Stones in the Thunder Plains. A spectral Qactuar will then appear, and you must follow it to a broken tower, then send a bolt of lightning through it. The chest will then appear.
The Saturn Crest is found near the top of Mt. Gagazet, where Seymour Flux was fought. The crest is hidden just past that spot, being between pillars on the left side of the path forward. To get the Saturn Sigil, you must win the Butterfly Hunt minigame in both areas it appears within the Macalania Woods, after obtaining the airship. After the second win, the chest will appear. Upgrading the Spirit Lance will allow Ixion to break the damage limit.
Lulu’s Celestial Weapon is the Onion Knight, and is arguably the hardest weapon in the game to fully realize. To obtain it, you must search for the coordinates ’12, 57’ on the airship, and travel to the location in Baaj that appears. Once there, you must dive into the water and swim to the northern doors, where Geosgaeno will attack you. After the fight, the weapon will appear in the southern part of the underwater area.
The Venus Crest is found in the Farplane after Tidus mentions Seymour’s departure for Macalania Temple. To obtain the Venus Sigil, you must go to the Thunder Plains and dodge 200 bolts of lightning in a row, without leaving the area or reloading the game. Once you have dodged 200 or more, the chest will appear in front of the Thunder Plains Travel Agency. Upgrading the Onion Knight will allow Shiva to break the damage limit.
Auron’s Celestial Weapon is the Masamune. To get it, you must first find the Rusty Sword on the eastern cliff outside of the Cavern of the Stolen Fayth. Afterwards, travel to the Djose end of Mushroom Rock Road, and take the Northwestern passage that leads to a rising platform. Go up the statue, and offer the Rusty Sword to the statue of Lord Mi’ihen, and a nearby glyph will appear. Interact with it, and you will obtain the weapon.
The Mars Crest is found near the entrance to Mushroom Rock Road, in the final area of the Mi’ihen Highroad. Follow a long, narrow series of passages that leads Southeast, and the Crest will be at the end of the path. The Mars Sigil is obtained by doing some of the Monster Arena side quest. You must unlock a total of ten Area Conquest or Species Conquest monsters (it can be any combination of these two). Once ten are unlocked, you will get the Sigil. Upgrading the Masamune will allow Yojimbo to break the damage limit.
Rikku’s Celestial Weapon is the Godhand. To find it, enter “GODHAND” as a password on the airship, and travel to the unlocked location on Mushroom Rock Road. Once there, simply follow the path North, and you will find the chest.
