The Excalibur is a greatsword in Final Fantasy XII. Its attacks deal Holy damage. In the original version, its license costs 160 LP. In the Zodiac versions, its license costs 135 LP and it can be used by the Knight. The Zodiac versions also have a counterfeit to the Excalibur as a joke weapon, the Excalipur.
In The Zodiac Age version, the player can choose two License Boards for each party member. Pairing Knight with Bushi is considered one of the best combinations, and it allows the character to deal extreme damage (now that the damage cap has been removed) with the Excalibur if they equip the White Robes, which boost all Holy damage dealt by the user by 50%.
Excalibur is King Arthur's sword, the one he obtained from the Lady in the Lake, after the one he pulled from the stone broke. Excalibur itself is thought to be derived from Caladbolg, which in itself may be drawn from the Welsh Caledfwlch, which can be latinised as Caliburnus. The legends state the sword was virtually peerless and only passed to the chosen. However, King Arthur was mortally wounded while wielding the sword by his son, Mordred in the battle of Camlann. Upon his death, it was either Sir Lancelot or Sir Griflet who, after much hesitation about discarding such a powerful sword, returned the Excalibur to the Lady in the Lake.The
