In Final Fantasy X, each character has their own Celestial Weapon. These are the best weapons to obtain and have long been a part of the series, although, until this adventure in the world of Spira, were otherwise known as Ultimate Weapons or Sealed Weapons.
The Celestial Mirror
Before you start collecting the Celestial Weapons in Final Fantasy X, you will first need to obtain the Celestial Mirror. First, you will need to visit the Remiem Temple to take part in a Chocobo race beneath the ancient structure. If you win, you will receive the Cloudy Mirror as a reward for your efforts.
After this, head to Macalania Woods where you will be able to turn the otherwise unassuming Cloudy Mirror into the Celestial Mirror.
Once you find the mother and child in the south part of the woods, they will explain that they are waiting for their husband (or father). Head east from here and then west to reach the campsite, where he is standing around. After talking to him, he will race back to his family.
However, after following him you will soon learn that their child has now gone missing. If you use the Save Sphere as a starting point, use the crystal path that leads north from Macalania Woods – Central. Here, you will find the young boy, and, after examining the large crystal nearby, the Cloudy Mirror will turn into the Celestial Mirror.
This part is necessary, as you will need to return to this place to release the power of each Celestial Weapon once you collect them and their respective crest and sigil.
Tidus’ Celestial Weapon: Caladbolg

And then you will need the Sun Sigil. For this, you will need to beat the Catcher Chocobo race in the north-western Calm Lands in under zero seconds. There are four training exercises that the Chocobo Trainer will challenge you with – the Catcher Chocobo session being the fourth.
Your goal is to finish the course in the shortest time. Three seconds will be deducted from your overall time for each balloon that you collect, but, if you hit any birds, you will receive a time penalty. Your success will largely be down to luck, but make sure to keep in front of the Chocobo Trainer to make sure that you can collect the most balloons.
