I believe it requires Random to have a specific amount of MN to succeed. I'm not sure I ever tested this personally though, it could just be a myth.
It would be a good idea to collect any quests and bonuses that boosts Random's MN permanently, before just grinding your way to success. If all else fails, there is a Fairy in the western woods you can buy an MN boosting status effect from. I believe the buff wears off after battle though, so you would need to avoid every encounter until you reach Enya with the status effect still on Random.
