In recent years, demand from collectors and historians has led to a surge of adventurers seeking tomestones, those mysterious relics of the Allagan Empire made to record and keep its secrets. Some small number of the artifacts, unique for the peculiar sort of knowledge contained within, have piqued the interest of the eccentric─in particular, itinerant moogles, who come bearing rare goods of their own to exchange for these "irregular" tomestones.

Irregular tomestones of philosophy will not be awarded under the following conditions:
・Using the Unrestricted Party Option
・Joining a Party in Progress

Exchange irregular tomestones of philosophy with an itinerant moogle for various items.

・Irregular tomestones of philosophy can only be obtained during the event period.
・Item exchanges will be available until the release of Patch 5.1.
