In the upcoming June version of Final Fantasy XI, several changes will be made to the Adventuring Fellow and Trust Initiative Alter Ego systems, to make your NPC allies more useful than ever! Trust NPCs will now be able to be summoned in several new battlefields, such as Skirmish areas and Seekers of Adoulin missions, and can be called out while in parties with other players.

Adventuring Fellows will also be seeing an addition to areas they can be summoned in, being now available in both outdoor and dungeon areas from the Seekers of Adoulin expansion!

Excited for these new changes to your NPC friends? Let us know about it over on the ZAM forums!
