Most expensive item in DotA 2

Battle in DotA 2 requires great concentration, which is why having a good in-game animal courier to ferry purchases from the item shops in the DotA 2 arena to the front lines is essential. The most expensive DotA 2 item sold at auction was a particularly rare ethereal flame pink War Dog courier, which was sold by player "PAADA" to an anonymous bidder on the Dota2Trade subReddit for $38,000.

The ethereal flame pink War Dog courier is so coveted because of the rarity of its colour and flame effect.
