I read http://www.battle.net/diablo2exp/items/crafteditems.shtml to try and understand what it was and how it worked but I don't really understand. Does anyone have a simpler way of getting me to understand what and how a ilvl works, I'm trying to craft some items but I don't understand the ilvl thing. Could someone be nice enough to tell me in a less detailed way?

ilvl = item level
