The current Project EQ database, accessible at
www.projecteq.net, contains a finely tuned set of mobs, factions and loot for up through and including the Velious expansion. It's not perfect, and it has only up to Velious, but it's the result of both packet collection from eqlive to get real pathing and levels, pulling from web resources to get real factions and loot drops, and enough player input to fill up a terrabyte drive. (Not quite, but dangit we're getting there

)
To answer the next question (don't act like you weren't gonna ask it

) -- sorry but no, you cannot graft this database onto what you currently have. I don't really know what database you got but you'll have to clear the tables first before loading this one, if you want to use it. I guess it's mostly a quantity vs quality decision.
