The Dhanusha is a bow in Final Fantasy XII. It is an upgraded version of the Sagittarius introduced in the Zodiac versions. It is not the strongest bow by a long shot as the secret weapon Seitengrat offers over double its attack stat, over seven times its evasion, over three times as quick, an even greater critical rate (Dhanusha is 4x the bow standard, while Seitengrat is 5x it), and twice the range of all other long range weapons. The Seitengrat also becomes available as soon as the Skyferry can be traveled on, does not require a license to use, and multiple copies can be obtained. The drawback of Seitengrat is that is meant to be that it is absurdly difficult to obtain even if one knows of its existence, but due to RNG manipulation even that is not necessarily the case.
Its license costs 200 LP and it can be used by the Archer.
Dhanusha is made at the bazaar by selling three Beastlord Horns and Moon Rings and four Sagittarius Gems. It costs 100,000 gil. Beastlord Horns are obtained from Humbabas that carry a sword, as well as stolen from Catoblepas, Fenrir, and Humbaba Mistant. Moon Rings are obtained from Ash Wyrms. Sagittarius Gems are obtained from some flan type enemies, like Foobar and Hecteyes.
In Hindu astrology, Dhanuṣa stands for the zodiac sign Sagittarius.
It is called Sagittarius A in the Japanese version, with all the letters at the ends of the newly added upgraded weapons spelling out "FINAL FANTASY".
