Killer Guides provides an extensive selection of guides for the online game Final Fantasy XI (commonly referred to as "FFXI"). Offered products include job guides, expansion guides and gil making guides.

For the most popular class in Final Fantasy XI, the red mage (RDM), Killer Guides provides an extensive FFXI Red Mage Guide. From a RDM-specific leveling guide, to playing the job in groups it provides a deep insight into low and high level strategies.

The in-game currency in Final Fantasy XI is Gil. Since nearly all items and professions require a starting Gil investment, the Final Fantasy XI Gil Guide comes in quite handy. From gardening to chocobo digging it provides several different gil-making strategies.

One of the more evil characters in FFXI is the Dark Knight. The counterpart to the Paladin can be compared to Shadow Knights in other MMORPGs. With the Final Fantasy XI Dark Knight Guide players receive a manual that explains skills, traits, spells and weapon choices for the job.

The second expansion for FFXI is commonly referred to as CoP, which stands for Chains of Promathia. CoP comes with a deep storyline and provides new grinding opportunities and gil-making methods for players. The newly introduced strategies, tactics and locations are explained in a Chains of Promathia Guide - also available on Killer Guides.
