Here’s the DotA 2 Items, Recipe list you have been waiting for, a fellow Dota player gathered DOTA 2 Item icons from official Valve DotA 2 server and put them in sequence. He made a chart showcasing DotA items against DOTA 2 which will allow you to easily differentiate between the items. Valve has included approximately all the items from Warcraft 3 DotA. They have worked a lot to remove the Warcraftish look from the DotA 2 Items and renamed some of them so, they keep themselves away from getting any legal threats from the competitors.
The DotA 2 Items and Recipes above were revealed during the DOTA 2 ‘The International’ event at Gamescom though they provide so much eyecandy but they still need to be reworked. There’s a clear chance that Valve might change those icons during the DOTA 2 Beta phase or when game releases.
