Let's hope this typo doesn't make it into the game proper:

Blade of the Sephirot
Axe of the Sephirot
Cane of the Sephirot
Fists of the Sephirot
Pike of the Sephiroth
Bow of the Sephirot
Points of the Sephirot
Staff of the Sephirot
Word of the Sephirot
Song of the Sephirot
Edge of the Sephirot
Fire of the Sephirot
Star of the Sephirot
Shield of the Sephirot

You knew the typo would happen eventually. :P
