Final Fantasy XI: Seekers of Adoulin official website, shining a light on the abilities of the new Geomancer job and on the Naakuals, seven of the fiercest creatures in Adoulin. The Geomancer will be bringing a number of nifty new mechanics to the table, though perhaps the most interesting of these is the job's use of luopans. Luopans are described as "geomantic catalysts" that "act as the epicenter for special spherical fields termed 'colures.'" The Geomancer can place a luopan anywhere on the ground and activate it to cast a geocolure spell, which can provide buffs to nearby allies or debuff nearby enemies.
And from the looks of things, players will need all the help they can get in order to take down the dreaded Naakuals, described as "the seven most bloodthirsty hellions that reign over the wilds surrounding Adoulin." Three of these Naakuals have been revealed on the expansion's site. The first is Tchakka, the Riptide Naakual, which takes the form of a nasty shark-like rockfin. There's also Achuka, the Firebrand Naakual, representing the dinosaur-esque gabbrath family, and Colkhab, the Matriarch Naakual, the most dangerous of the bee-like bztavian family. To have a look at these ferocious foes for yourself, head on over to the FFXI: Seekers of Adoulin official site.
