Dio's Best Friend

Dio's Best Friend is a item in Risk of Rain that revives the player once upon death, refilling 40% of their HP.

Trivia
This item has a delivery date of 1993, which is drastically different to most other items in game and is impossible without bending time, assuming that the date of the game's events are in the future from the present day.

The name Dio is a reference to Duncan Drummond's cat. He is one of the developers of Risk Of Rain. This can be found under the "Team Section" on the official site.

This item and the Time Keeper's Secret are the only two items that are consumed upon use.

If you use one of these items after picking up two, the icon will still say you have two.

The word "dio" means "god" in Italian, referring to how you are given another life by literally being god's best friend.
