Neutral Items is the newest feature that has been added in Dota 2 along with the arrival of two new heroes.
In Dota 2 update 7.23, neutrals can now drop unique items that can be used by you and your team. However, these items cannot be sold in the market. Item drops begin at the 5-minute mark of the game and backpack slots will be increased from 3 to 5 to help carry items. Check out the list below for the full list of items that will be dropped by neutrals throughout the game.
