The Kumbha is a weapon in Final Fantasy XII. It is the upgraded Masamune added to the Zodiac versions. The Kumbha is rather unique, as in spirit it is a katana, however, it improves over other katanas by being one-handed, which makes it technically a one-handed sword. Its damage formula and stats are more like a katana's though, and its license is only found on the Bushi board, the only board for katana users.
In addition to being the strongest spiritual katana, it is also the longest short-range weapon with double the reach of all other short-range weapons.
A red zigzag pattern runs the length of the blade, weaving its way across delicate inlay.
Kumbha is obtained through the Master-crafted Blade bazaar set. The player needs to sell two Gemsteels, three Orichalcums and two Mallets, and pay 350,000 gil. The Gemsteels need to be created at the bazaar, the Orichalcums are obtained from Deidar and Vishno, and Mallets are obtained from Purobolos and Bombshell, as well as Montblanc for defeating King Bomb.
In Hindu astrology, the kumbha stands for the zodiac sign Aquarius and is also associated with the Kumbh Mela, which happens when the planet Brihaspati moves into Aquarius.
It is called Masamune I in the Japanese version, with all the letters at the ends of the newly added upgraded weapons spelling out "FINAL FANTASY".
