Einherjar ( Final Fantasy XI ) Einherjar is a massively multiplayer battlefield system in " Final Fantasy XI " . It is set in the Hazhalm Testing Grounds , an area once employed for the most profane alchemical experiments . One such operation inadvertently created a portal between Vana ' diel and the ethereal domain of Odin , the Dark Divinity . Hazhalm was subsequently evacuated and magically sealed by the Empire of Aht Urhgan . Not all of the scientists involved were content to abandon the site , however , and one , an Elvaan named Kilusha , entices adventurers to break into the testing grounds in order to salvage her research . Participation . As few as six or as many as thirty - six players may assemble to participate in Einherjar . Each applicant must be at least level 60 and have completed the first errand given by Naja Salaheem as an introduction to the Near East . Having purchased a special lamp from Kilusha for 180 , 000 gil , one may reserve an unoccupied portion of Hazhalm for half an hour and trade duplicate lamps to allies to enable their entry . With the lamp - purchaser leading the way , the party may delve into the testing grounds and face its sinister residents . Once standing in Hazhalm , adventurers are not allowed to enter Einherjar again for three days . They must therefore be careful not to exit the area prematurely . Everyone will be automatically removed from Hazhalm if all party members have been knocked out for more than three minutes . Players are also barred from participating if battle begins before they have gone inside . Like Dynamis , Einherjar was originally designed to entertain large groups of well - prepared level 75 players . With the higher level caps introduced since the June 2010 version update it has become increasingly easy to complete Einherjar with smaller parties . Teams of less than six people have only ten minutes before their reservation is canceled and they are ejected from Hazhalm , however . Progression . The Hazhalm Testing Grounds are divided into three wings which are themselves partitioned into three large , creature - infested chambers . Nine rooms therefore exist for players to reserve and conquer . Only the first wing is initially available , however . Among the enemies in each chamber is a randomly - selected Guardian of Asgarth that serves as a boss . Having defeated these leaders and their subordinates , adventurers receive a feather corresponding to the current chamber . Holding all three feathers from the first wing allows a reservation to be placed in the second wing while holding the second wing ' s feathers allows reservations in the third . Participants other than the lamp purchaser may follow regardless of how many feathers they have collected . Those who obtain all nine feathers may make a reservation for Valgrind , the location of Odin ' s personal chamber . Accompanied by players with at least one feather from each of the previous wings , the lamp purchaser may lead a charge against the Dark Divinity and his summoned servants . All party members lose all accumulated feathers upon setting foot in Odin ' s domain . Succeeding in this tenth chamber entitles players to reserve any of the previous wings without completing them in order . Gameplay . Having reserved a chamber , a party has thirty minutes to clear the area . There are no time extensions and any loot left undistributed when time expires is lost . Players therefore proceed briskly through the monstrous horde and powerful guardian that await them . All participants are rewarded with Therion Ichor , a substance much desired by the scientist Kilusha , proportional to the quantity of opponents that are defeated during the expedition . Defeating all enemies not only awards the chamber ' s feather but also amplifies the ichor received and creates a crate full of additional prizes at the center of the chamber . Much like Dynamis , participants are not required to be formally grouped as a party or alliance and everyone present inside Hazhalm may attempt to claim any loot that appears . As adventurers work through a chamber a special Notorious Monster will spontaneously appear nearby . These creatures affect Einherjar in various ways if they are defeated and may make the battle more difficult if they are not engaged . Huginn , a bird , will leave a box of consumable items when killed . The defeat of another avian , Muninn , calms enemies while failing to destroy Saehrimnir , a tiger , makes foes more restless . Vanquishing Heithrun , a very rare sheep , will double the treasure received in the final chest .
