For some nice tutorials, check these great ones out that GeorgeS was kind enough to write (note some parts use GeorgeS' tools for assistance):
EQEMU NPC Spawning Tutorial:
http://www.georgestools.eqemulator.n...tut/index.html
Creating NPC's Pathing:
http://www.georgestools.eqemulator.n...ng_spawns.html
Both of those Tutorials are very useful, especially for people just starting out. I even still reference the pathing one when I do pathing sometimes, because I always have trouble remembering which option is which for creating grids lol.
