All Saints' Wake is a time for terrible frights and monstrous delights, when Eorzea's people dress as ghastly fiends for a night of tricks and treats. To celebrate this year's All Saints' Wake, adventurers across the realm have been called upon to take after the dreaded doppleganger, guising themselves as their favorite NPC or monster! After choosing your victim and donning your costume, strike a pose next to them and take a screenshot. The hundred best images will win a special in-game item for their efforts.
Those who wish to fool their friends should head over to the official forum for details!
