Happiest Mask

The Happiest Mask is a returning item in Risk of Rain 2. When the holder kills an enemy, there is a small chance that a ghost of that enemy will spawn as an ally. The chance for this to happen is affected by Luck.

The ghost inherits all behaviors of the original monster. The level of the ghost equals the "ambient" level of the run, not the player's level.

Trivia

 * The ghosts are actually the original monsters with three special hidden items equipped. One makes its health deplete over time; ghosts are awarded 30 of these per Happiest Mask the user has. The second makes it appear and behave like a ghost. The third boosts its damage; the ghost is supplied 150 of these.
 * Because the time a ghost lasts is tied only to a damage-over-time item it receives, it is possible that ghosts can survive indefinitely because of their healing ability.
