I need to look first on my backup archive if i still have it.. but anyway what it does is it's same with @item command and the syntax is something like this:
@itemmap <map name> <item id/name> <quantity> something like that if i remember it right, I have this on my previous Server got it from eAthena it was posted/modified by Rad Santos but was originally made by Cid *something* I don't remember lol and I'm not quite sure. so what it does is, it gives item to every Player who are on the Map.
well this is a nice Command for giving out Rewards/Gift for your beloved Players
