Dragon Quest X version 1.5 is in development and when the update comes out Meena from Dragon Quest IV will be in it. Meena is a playable character in Dragon Quest IV’s fourth chapter and she is a fortune teller investigating her father’s murder. Meena can cast magic spells and draw tarot cards in battle which act somewhat like spells during the fight (and not all of them are in favor of the party!).
Meena is still a fortune teller in Dragon Quest X. You can ask her to give you a fortune which will have different effects on the party.
Dragon Quest X is available for Wii and Wii U in Japan. Square Enix also announced plans to bring the MMORPG to PC this September.
