Relics

Relics are objects that, when used, provide you with a temporary magical affect.  These items require the use of MP.  A Relic can be equipped using the Real Time Window under Relics or by holding down the L2 button to open the Relic Window and scroll them using the right analog stick.  Pressing R1/R2 & Circle will activate/deactivate the Relic.
