Dio's Best Friend is a returning item in Risk of Rain 2.
Upon dying, the character will revive after a few seconds. This will trigger any on death effects, such as the ice explosions from Glacial Elites. Upon reviving, they will get 3 seconds of invincibility. and the item will be consumed.
- Works on Engineer's turrets (all variants). Redeploying gives them a new, unused teddy bear (as long as you have yours unused).
- Before the Skills 2.0 update, using a Shrine of Order made all consumed Friends disappear due to not having an item tier. Now, it simply leaves them alone.
- 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.
- In Risk of Rain 1, the achievement to unlock this item is known as "Sole Survivor". This is a reference to a lyric in the song 'Holy Diver' by Dio, the artist of which where Duncan's cat gets its name from.
