"Holy sword with the legend of Mysidia inscribed."
—Description
The Mythgraven Blade(伝説の剣,Ken no Densetsu?), also known as Sword of Legend or simply Legend in the SNES and PlayStation versions, is the sacred blade bestowed upon Cecil during the Mount Ordeals trial. Engraved on its blade are the words of the Mysidian Legend.
The Mythgraven Blade is the first weapon Cecil can equip when he is transformed into a Paladin. This weapon is metallic. It's a key item that cannot be sold or discarded by the player. It is useful as the only Holy-elemental weapon Cecil can use until he acquires the Light Blade in the Sealed Cave, and is effective against undead.
Later, the player can take this blade along with a piece of Adamantite (which can be obtained giving the man in the Mythril Caves a Rat's Tail), to Kokkol in his smithy in order to transform it into the Excalibur.
Mythgraven Blade is not a weapon that can be used by normal means, as it is only available via hacking. It stats differ greatly from its original appearance. It provides an Attack of 48, as well as +3 Spirit, and is Holy-elemental. In addition to Cecil, Ceodore and Kain could have also equipped it.
The Mythgraven Blade is an exclusive weapon for Cecil. It is a level 50 weapon that provides +37 Attack, increases Defense by 1 when Cecil is in Paladin form. It can be traded for in the shop for 16280 gil, a Dark Sword, three Gigas Bones, and Titan Shards.
The Mythgraven Blade returns as a level 30 exclusive weapon for Cecil, and provides -2 Defense, +42 Attack, and +Defense when a Paladin. It can be obtained at the Shop by exchanging 61000 gil, a Dark Sword, 1 Scarletite, and 2 Knight's Desire.
