I post my collection of path files on
www.eqpvp.com/paths -- probably be updating it again soon once I do some run testing around the new path files I have been working on this month.
My database/code is so off base from main eqemu. Highly modified since 2011 since I run custom servers (but on the classic setting). Just coming to mind I don't even have LUA scripting in there I am still using perl, plus the loot table design was rewritten recently. I can't suggest it as a base unfortunately because its been modified for my custom server (such as a Diablo item system that lets me create items on the fly during gameplay). Just a lot of things I don't think would fall in line with classic or would want to be part of that source.
