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.
