Happiest Mask (Risk of Rain 2)

Not to be confused with the first game's version, the Happiest Mask. The Happiest Mask is a returning Rare item in Risk of Rain 2. Killing enemies has a 10% chance to spawn a transparent ghost of that enemy to fight for you. They deal 500% damage, and last for 30 seconds per mask. Their remaining time can be determined from their health bars, as those are displayed on the left side of the screen.

The Ghosts are able to spawn from bosses, and can pick up logs. If an enemy both drops a log and spawns a ghost, the ghost will instantly pick up the log. The message will identify the ghost as "???".
