Tri-lock Sword

The Tri-lock Sword is a bladed weapon that has three locking mechanisms, which the user may unlock by accomplishing certain tasks. There are seven such swords known to exist.

Upon receiving the sword during a ritual, the first lock is opened. This allows the wielder to open it a few inches, with most of the blade still locked in the scabbard.

Each lock allows the wielder to learn a certain amount of abilities. Upon learning them all, a character transformation allows them to unlock the next one.
